  • New species may have just been discovered in rare

    New species may have just been discovered in rare

    [ad_1]

    A new species of octopus may have just been discovered off the coast of Costa Rica. It was found in a rare brooding site that marks only the third octopus nursery known to exist in the world. 

    The octopus nursery was first found in 2013 with roughly 100 female octopuses brooding at a cold hydrothermal vent off the coast of Puntarenas, Costa Rica. But at that time, researchers said that they didn’t see any developing embryos. That led them to believe that conditions there were not conducive to the baby octopuses being born.

    A 19-day expedition located a second site of low temperature (7oC) hydrothermal venting with brooding octopus on an unnamed outcrop that was explored for the very first time on this expedition. This is only the world’s third-known deep-sea octopus nursery, and the second site found in Costa Rica.

    But that all changed earlier this year, when a team of international researchers ventured back and saw the octopuses hatch. Their birth makes the area the world’s only third-known octopus nursery, and the first known nursery for a species of deep-sea octopus, in this case, the Dorado Outcrop. 

    In a press release, the Schmidt Ocean Institute said that researchers believe the mollusks may be a new species of octopus that stems from the Muusocotpus genus, which includes “small- to medium-sized octopus without an ink sac.” 

    “The discovery of a new active octopus nursery over 2,800 meters (9,186 feet) beneath the sea surface in Costa Rican waters proves there is still so much to learn about our Ocean,” the executive director of the Schmidt Ocean Institute, Jyotika Virmani, said in a news release. “The deep-sea off Costa Rica rides the edge of human imagination, with spectacular footage collected by ROV SuBastian of tripod fish, octopus hatchlings, and coral gardens.” 

    According to the institute, the Dorado Outcrop is the “size of a soccer field,” which is considered “small,” and there are an estimated 100 female octopuses brooding their eggs in the location. Scientists have been studying the nursery because of the odd circumstances surrounding it.

    “The behavior shocked cephalopod experts because octopuses were considered solitary creatures at the time. In the past, octopuses were observed fighting over territory or mating toward the end of their life,” the Institute says on its website. “Female octopuses are known to brood their eggs alone in rocky crevices, passing away after their eggs hatch.”

    They also didn’t see any embryos developing when it was first discovered.

    Octopuses are often seen brooding in warm waters to reduce the amount of time it takes for the eggs to hatch. 

    In 2018, it was found that more than 1,000 members of a different species of octopus had nested in a warm geothermal spring nearly 2 miles underwater off the coast of California. That octopus garden was a little shallower, at nearly 1 3/4 miles underneath the ocean surface. 

    On their 19-day expedition in Costa Rica, researchers also discovered five never-before-seen seamounts, the Institute said. Those areas, including the area where the octopus nursery was found, are not currently protected, but were found with “thriving biodiversity,” prompting some of the researchers to investigate whether those areas can be designated as marine protected areas. Under that designation, the sites would be preserved and protected by local organizations and the government. 

    “This expedition to the Pacific deep waters of Costa Rica has been a superb opportunity for us to get to know our own country,”  Dr. Jorge Cortes of the University of Costa Rica said in a press release. “The expedition had a significant number of local scientists and students which will accelerate our capacity to study deep regions. The information, samples, and images are important to Costa Rica to show its richness and will be used for scientific studies, and outreach to raise awareness of what we have and why we should protect it.”

  • How a robot fish

    How a robot fish

    [ad_1]

    The mysteries of the ocean abound. And now, a group of student researchers is trying out a new way to gain better and more accurate information – with a robot fish. 

    The robot, named Belle, was created by students at the university ETH Zürich. They designed the fish so that it can swim underwater to film and collect samples without disturbing the natural environment. 

    “The idea was that we want to capture the ecosystems the way they actually behave,” student researcher Leon Guggenheim told Reuters. “… That’s why we then developed the fish that behaves like a fish and is also accepted by other marine creatures as a fish.” 

    That requires two things that the students say they accomplished: Making it move like a fish and being silent. 

    “We want to really go in there and be as silent as a spy,” assistant professor of robotics Robert Katzschmann said, “and just literally coming in and being a spy on the marine life.”

    And it takes a full-body experience to make it happen. 

    The “head” of the roughly 3-foot-long robot fish is what contains the electronics and camera, Guggenheim said, and is “the only proper waterproof part” of the device. The “belly” of the fish is where the battery and motors lie, as well as the filter and pumps that allow the robot to capture environmental DNA. 

    Environmental DNA capture is a “more sophisticated option” in gathering biodiversity information underwater, Guggenheim said. It entails using a filter to catch fine particulars, including larvae and algae, that researchers then use to extract DNA and see what creatures are in a certain area.

    The final part of the robot fish, the fin, is made of silicone and contains two cavities that are filled and emptied with water through internal pumps that help the nearly 22-pound robot move. 

    And much like a real fish, this one must also be found and caught when it’s time to reel it in to go home. Guggenheim explained that the device can’t connect to radio frequencies, so when it swims to the surface after about two hours of data-gathering, it emits a GPS signal that tells researchers where to pick it up. At that point, the filter needs to be emptied and the batteries need to be replaced.

    The team hopes that their device will make ocean exploration safer for the living things that reside within. 

    “Oceans are severely under pressure from overfishing, from pollution, from climate change, and we know fairly little about them,” Guggenheim said. “…It covers 70% of our oceans, so it’s very hard to get accurate, good amounts of accurate data on the biodiversity in these ecosystems.” 

    Katzschmann said that current research typically relies on unmanned vehicles that can be “definitely very disturbing” to ecosystems and aren’t made for delicate environments. 

    “Those areas are particularly vulnerable to propeller-based systems that would just sort of shred through the corals or go and scare the fish away,” he said. “So that’s not our goal, right?”

    Ocean exploration and research continue to be a vital priority worldwide. According to the National Ocean Service, “the ocean is the lifeblood of Earth” and covers about 70% of its surface. It helps regulate weather, climate, temperature and life for all – including humans. 

    But more than 80% of the ocean remains untapped, and marine biodiversity – which these researchers are hoping to be able to better study – is “critical” in helping life on Earth thrive, according to the U.N. 

    “Evidence continues to emerge demonstrating the essential role of marine biodiversity in underpinning a healthy planet and social well-being,” the U.N. said in 2017. 

    And the students’ new device embodies the goals of the U.N.’s historic High Seas Treaty. Passed just weeks ago, the treaty puts a more concerted effort into marine conservation and protecting marine environments. 

    “The high seas are among the last truly wild places on Earth,” Monica Medina, the Assistant Secretary of the U.S. Bureau of Oceans and International Environmental and Scientific Affairs, previously told CBS News’ U.N. correspondent Pamela Falk. “…The ocean is more fragile than most people understand. It is also more essential.”

  • Missing sub passenger knew risks of deep ocean exploration:

    Missing sub passenger knew risks of deep ocean exploration:

    [ad_1]

    A submersible carrying five people to the ocean floor to see the long-sunken RMS Titanic has gone missing — and one of those passengers knew from a previous expedition to far greater depths that a situation like this could be deadly. 

    Just two years ago, wealthy British businessman Hamish Harding made it to the deepest part of the ocean. He traveled with U.S. explorer Victor Vescovo more than 2 and a half miles along the floor of the Mariana Trench, 35,876 feet below the sea surface. That trip, in a $48 million submersible, earned both explorers the Guinness World Record for the longest distance traveled at the deepest part of the ocean by a crewed vessel.

    It was a mission he was proud to accomplish, but also one that he knew could pose disastrous consequences. 

    “It was potentially scary, but I was so busy doing so many things—navigating and triangulating my position—that I did not really have time to be scared,” Harding told India news outlet The Week after the excursion.

    Just like the now-missing Titanic submersible, the one he took down to the trench had an estimated four days of oxygen on board as a safety measure. But he told The Week that amount wouldn’t be enough should problems arise at great ocean depths. 

    “The only problem is that there is no other sub that is capable of going down there to rescue you,” he said. “…So, having four days of supply doesn’t make a difference really. If something goes wrong, you are not coming back.”

    On the current OceanGate expedition, Harding and his fellow passengers encountered just such a harrowing situation. The sub, which went missing on Sunday about 900 miles east of Cape Cod, had less than an estimated 40 hours of breathable air left as of Tuesday afternoon, making search and rescue operations dire. 

    Once that time expires, there wouldn’t be an automatic transition to a recovery operation, Coast Guard Capt. Jamie Frederick said Tuesday, adding that the future of the “incredibly complex operation” is determined by several factors. 

    Shortly after midnight on Wednesday, the Coast Guard said crews had picked up underwater noises in the search for the sub. So far, however, they have not found what created the noises. 

    OceanGate, the company leading the trip to see the Titanic wreckage, also led expeditions to the site in 2021 and 2022, and says on its website that it planned to do so every year. Along with including “qualified” civilians on the trip, OceanGate also sends crewmembers who can lead research on the ship’s debris.

    Harding shared a message on his Facebook page Saturday about plans for his upcoming adventure: “I am proud to finally announce that I joined OceanGate Expeditions for their RMS TITANIC Mission as a mission specialist on the sub going down to the Titanic.”

    “A weather window has just opened up and we are going to attempt a dive tomorrow,” he wrote. “…More expedition updates to follow IF the weather holds!”

    What we know about Stockton Rush, the Titan submersible’s pilot | CNN Business

    [ad_1]


    New York
    CNN
     — 

    Stockton Rush, the CEO of OceanGate and one of five people on the submersible missing in the North Atlantic, has cultivated a reputation as a kind of modern-day Jacques Cousteau — a nature lover, adventurer and visionary.

    Rush has approached his dream of deep-sea exploration with child-like verve and an antipathy toward regulations — a pattern that has come into sharp relief since Sunday night, when his vessel, the Titan, went missing.

    “I think it was General MacArthur who said you’re remembered for the rules you break,” Rush said in a video interview with Mexican YouTuber Alan Estrada last year. “And I’ve broken some rules to make this. I think I’ve broken them with logic and good engineering behind me.”

    Rush, who graduated from Princeton in 1984 with a degree in aerospace engineering, has said that he never really grew out of his childhood dream of wanting to be an astronaut, but his eyesight wasn’t good enough, according to an interview he gave Smithsonian Magazine in 2019.

    After college, he moved to Seattle to work for the McDonnell Douglas Corporation as a flight test engineer on the F-15 program. He obtained an MBA from UC Berkeley in 1989, according to his company bio.

    He nursed his space travel dream for years, imagining he would join a commercial flight as a tourist. But in 2004, he told Smithsonian, the dream shifted after Richard Branson launched the first commercial aircraft into space.

    “I had this epiphany that this was not at all what I wanted to do,” Rush told the magazine. “I didn’t want to go up into space as a tourist. I wanted to be Captain Kirk on the Enterprise. I wanted to explore.

    Rush founded OceanGate in 2009, with a stated mission of “increasing access to the deep ocean through innovation.”

    As CEO, Rush oversees the Everett, Washington-based company’s “financial and engineering strategies” and provides a “vision for development” of crewed submersibles, according to his bio.

    OceanGate currently operates three submersibles for conducting research, film production, and “exploration travel,” including tours of the site of the Titanic more than 13,000 feet below the ocean’s surface. A seat on that eight-day mission costs $250,000 per person.

    Rush, who is 61, said he believes deeply that the sea, rather than the sky, offers humanity the best shot at survival when the Earth’s surface becomes uninhabitable.

    “The future of mankind is underwater, it’s not on Mars,” he told Estrada. “We will have a base underwater … If we trash this planet, the best life boat for mankind is underwater.”

    In his eagerness to explore, Rush has often appeared skeptical, if not dismissive, of regulations that might slow innovation.

    The commercial sub industry is “obscenely safe” he told Smithsonian, “because they have all these regulations. But it also hasn’t innovated or grown — because they have all these regulations.”

    Even within OceanGate, warnings from employees about safety appear to have been ignored or disregarded.

    David Lochridge, OceanGate’s former director of marine operations, said in a court filing that he was wrongfully terminated in 2018 for raising concerns about the safety and testing of the Titan. The case was settled out of court, and the terms weren’t disclosed.

    Another former employee, who spoke on the condition of anonymity, echoed Lochridge’s concerns. That employee said that as contractors and employees raised red flags, Rush became defensive and dodged questions in staff meetings.

    OceanGate hasn’t responded to CNN’s request to comment.

    In recent days, as search teams have scoured the ocean for signs of the Titan and its crew, some aspects of the vessel’s design and on-board technology — such as the a videogame controller that the pilot uses to steer it — have raised eyebrows.

    When CBS correspondent David Pogue took a trip on the Titan last year, he reported that communications broke down and the sub was lost at sea for more than two hours. He also asked Rush about what the vessel’s “MacGyvery” components — like the plastic PlayStation controller and LED lights that Rush bought from an RV retailer.

    Rush pushed back against Pogue’s description in that interview, arguing that some elements could be less sophisticated as long as the key parts, like the pressure vessel, is sound. Rush said the pressure vessel had been built in coordination with Boeing, NASA and the University of Washington. Once you’re certain that the pressure vessel is not going to collapse on everybody, he said, “everything else can fail.”

    “It doesn’t matter. Your thrusters can go. Your lights can go. All these things can fail. You’re still going to be safe. And so, that allows you to do what you call MacGyver stuff,” he said.

    Pogue, in an interview with USA Today on Wednesday, recalled his impressions of the Titan. “Some of the ballasts are old, rusty construction pipes. There were certain things that looked like cut corners.”

    Extreme tourism is a lucrative, high-risk industry. And it’s only growing. With enough money, tourists can summit Everest, take a rocket to space, run multi-day ultramarthons catered by Michelin-rated chefs, or plumb the oceans depths that have largely been off-limits for humankind.

    “What I’ve seen with the ultra-rich — money is no object when it comes to experiences,” said Nick D’Annunzio, the owner of public relations firm TARA, Ink. “They want something they they’ll never forget.”

    In that respect, Rush shares something in common with his clients. In his interview with Smithsonian in 2019, he relayed his almost-spiritual attraction to the deep sea. He called it “the deep disease.”

    “I went to 75 feet. I saw cool stuff. I went 100 feet and saw more cool stuff. And I was like, ‘Wow, what’s it gonna be like at the end of this thing?’”

  • Searchers detected banging while scouring the Atlantic for a manned submersible now running out of oxygen | CNN

    Searchers detected banging while scouring the Atlantic for a manned submersible now running out of oxygen | CNN

    [ad_1]



    CNN
     — 

    Banging sounds have been picked up from the Atlantic Ocean in the hunt for the submersible that went missing while touring Titanic wreckage with five people onboard, signaling “continued hope of survivors,” according to a US government memo, even as the craft’s oxygen dwindles.

    As rescue efforts keep ramping up, the underwater sounds were detected Tuesday by sonar devices deployed to find the 21-foot vessel that lost contact Sunday. The banging first came every 30 minutes and was heard again four hours later, the internal government memo obtained by CNN states.

    FOLLOW LIVE UPDATES

    While the underwater noises, detected by a Canadian P-3 aircraft, prompted the relocation of resources to explore their origin, “searches have yielded negative results,” the US Coast Guard tweeted early Wednesday, as less than a day of breathable air may be left on the vessel, based on agency officials’ latest estimate.

    “Additional acoustic feedback was heard and will assist in vectoring surface assets and also indicating continued hope of survivors,” according to a Coast Guard update Tuesday night.

    It was unclear when exactly the banging was heard Tuesday or how long it lasted, based on the memo. Rolling Stone was first to report news of the banging.

    “We don’t know the source of that noise, but we’ve shared that information with Navy experts to classify it,” US Coast Guard First District Commander Rear Admiral John Mauger told “CBS This Morning” on Wednesday.

    He described there being a lot of metal and other debris in the water around the Titanic site, adding, “That’s why it’s so important that we’ve engaged experts from the Navy that understand the science behind noise and can classify or give us better information about what the source of that noise may be.”

    While that analysis is taking place, Mauger said, two remote operated vehicles and one surface vessel that has sonar capability have been sent to the area where the banging was detected.

    The submersible known as Titan was carrying a pilot and four “mission specialists” when it lost contact with its mother ship about 1 hour and 45 minutes into its dive, authorities said. The craft is operated by OceanGate Expeditions, which organizes journeys to Titanic’s wreckage on the ocean floor for $250,000, an archived version of its website shows.

    The trip was part of the growing business of wealthy adventure tourism, along with the space flights of Blue Origin and the rise of guided tours to Mount Everest, and reflects an ongoing fascination with the doomed steamship more than a century after it sank on its maiden voyage, killing more than 1,500 people.

    As the search for the Titan continues, CNN has learned of at least two former OceanGate employees who expressed safety concerns about the vessel’s hull years ago, including the thickness of the material used and testing procedures. The 23,000-pound craft is made of highly engineered carbon fiber and titanium.

    But the central focus now is the massive search: The US is moving in military and commercial assets as aircraft from the Canadian Armed Forces, the US Coast Guard and the New York Air National Guard continue to look above and below water, and France’s president has dispatched a research ship with an underwater robot to join the search Wednesday.

    If crews find the missing submersible deep in the ocean, authorities would face a highly complex mission to recover it and any survivors, said retired Navy Capt. Ray Scott “Chip” McCord, whose 30 years of experience includes overseeing several salvage operations.

    “There’s very few assets in the world that can go down that deep,” Scott said.

    The US Navy is sending subject matter experts and a “Flyaway Deep Ocean Salvage System” that can lift heavy undersea objects to assist in the search and rescue, a spokesperson said Tuesday.

    Still, the five people onboard face a dire situation, said David Gallo, senior adviser for Strategic Initiatives, RMS Titanic, which owns the exclusive salvage rights to the 1912 wreck site. If the submersible is intact, the passengers would be dealing with dwindling oxygen levels and fighting cold, he told CNN.

    Hypothermia would be an issue “if the sub is still at the bottom, because the deep ocean is just above freezing cold,” Gallo said. “It’s like a visit to another planet, it’s not what people think it is. It is a sunless forever, cold environment – high pressure.”

    Chilly conditions and lack of light means those onboard will need to conserve energy, said Joe MacInnis, a physician and renowned diver who’s made two trips to the Titanic wreck.

    “Resting, breathing as little as possible, and trying to keep calm – that is the most important thing,” he told CNN early Wednesday.

    US Coast Guard Capt. Jamie Frederick didn’t know Tuesday if there was enough time to save the five people onboard, but “we will do everything in our power to affect a rescue,” he said.

    Already, more than 10,000 square miles has been searched, Mauger said Tuesday, across a zone that covers an area about 900 miles east of Cape Cod, Massachusetts, and 13,000 feet deep. The Titanic lies at more than 2 miles below the surface.

    Aboard the Titan is OceanGate CEO and founder Stockton Rush, a source with knowledge of the mission plan said, along with British businessman Hamish Harding, Pakistani billionaire Shahzada Dawood and his son Sulaiman Dawood, and French diver Paul-Henri Nargeolet, according to relatives and social media posts. Officials have not publicly named those aboard.

    Learning of the underwater banging “raised my hopes through the roof,” Gallo said, adding, “PH Nargeolet, my very good dear friend, is the kind of person that if he were in that submarine that he would think this thoroughly through and would do something like that every 30 minutes.”

    If the sounds came from the submersible, it could be an indication the hull of the vessel is intact, Gallo said.

    But, he warned, “time is of the essence.”

    Amid the race to find the Titan, court filings reveal OceanGate years ago was confronted with safety concerns about the vessel. Two former OceanGate employees separately raised similar safety concerns about the thickness of submersible’s hull when they were employed by the company.

    David Lochridge, who worked as an independent contractor for OceanGate in 2015 and as its employee between 2016 and 2018, said he brought up concerns about the Titan’s hull, according to court documents.

    Lochridge said no non-destructive testing had been performed on the Titan’s hull to check for “delaminations, porosity and voids of sufficient adhesion of the glue being used due to the thickness of the hull,” according to a countersuit filed after Lochridge was sued by OceanGate in 2018 for allegedly sharing confidential information.

    When Lochridge raised the issue, he was told no equipment existed to perform such a test, the suit states. The lawsuit was settled and dismissed in November 2018; its terms were not disclosed, and Lochridge could not be reached for comment.

    There was much additional testing after Lochridge’s time at OceanGate, and it’s unclear whether any of his concerns were addressed as the vessel was developed, court filings from the company indicate.

    Another former employee of OceanGate who worked briefly for the company during the same period as Lochridge became concerned when the carbon fiber hull of the Titan arrived, he told CNN on the condition of anonymity because he is not authorized to speak publicly.

    The hull had only been built to 5 inches thick, while he said company engineers told him they had expected it to be 7 inches thick, he told CNN, echoing Lochridge’s concerns about its thickness and adhesion.

    When more concerns were raised by contractors and employees during his time at OceanGate, CEO Rush got defensive and shied away from answering questions during all-staff meetings, the other former employee said.

    When he raised directly to Rush concerns OceanGate could potentially be violating a US law relating to Coast Guard inspections, the CEO outright dismissed them, the former employee said, and that’s when he resigned.

    CNN has reached out to OceanGate for comment on the former employee’s claims.

    One of the individuals on the missing sub to the Titanic posted photos of it on Sunday before its launch. The photos were posted on a dive participant's business Instagram page.  They show the sub sitting in a cradle-like flotation device in the Atlantic Ocean.

    Safety concerns were also raised by The Manned Underwater Vehicles committee of the Marine Technology Society, which penned a litter to OceanGate in 2018 expressing concern over what it referred to as the company’s “experimental approach” of the Titan vessel and its planned expedition to the site of the Titanic wreckage, the New York Times reported Tuesday.

    “Our apprehension is that the current experimental approach adopted by Oceangate could result in negative outcomes, (from minor to catastrophic) that would have serious consequences for everyone in the industry,” the letter, obtained by the Times, reads in part.

    Specifically, the letter expressed concern over the company’s compliance with a maritime risk assessment certification known as DNV-GL.

    “Your marketing material advertises that the TITAN design will meet or exceed the DNV-GL safety standards, yet it does not appear that Oceangate has the intention of following DNV- GL class rules,” the letter says. “Your representation is, at minimum, misleading to the public and breaches an industry- wide professional code of conduct we all endeavor to uphold.”

    OceanGate has not responded to a request for comment on the letter.

    The last communication between the vessel and its mother ship, the Polar Prince, came in at 11:47 a.m. Sunday. The vessel was expected to resurface at 6:10 p.m. but did not do so, and authorities were notified at 6:35 p.m., according to Polar Prince co-owner Miawpukek Maritime Horizon Services.

    The mother ship communicates with the vessel by text messages, and it’s required to communicate every 15 minutes, according to OceanGate Expeditions’ archived website. “All those things we’re used to now – GPS, Wi-Fi, radio links – do not work under the ocean,” former Navy submarine officer Capt. J. Van Gurley said.

    Some parts of Titan are decidedly low-tech. Unlike a submarine, a submersible needs a mother ship to launch it, has fewer power reserves and can’t stay underwater as long.

“It is operated … by a gaming controller, what essentially looks like a PlayStation controller,” said CNN correspondent Gabe Cohen, who sat in Titan in 2018 while reporting on OceanGate Expeditions for CNN affiliate KOMO.

It’s a “tiny vessel, quite cramped and small,” Cohen said. “You have to sit inside of it, shoes off. It can only fit five people.”

The Titan is held underwater by ballast built to be automatically released after 24 hours to send the sub to the surface, said Aaron Newman, an investor in OceanGate who went down to Titanic on the Titan in 2021.

“It is designed to come back up,” he told CNN.

“It’s a very stressful situation,” John “Danny” Olivas, a retired astronaut who has completed two stays on NASA’s underwater habitat and trained on underwater space walks, told CNN.

“At those depths, they’re not getting a lot of ambient light,” he said, and if there’s been a loss of power, the vessel would get very dark and cold.

“There probably wouldn’t be any cabin air circulation, which could also pose a lot of potential hazards with just breathing the air. The oxygen is important, but also CO2 generation by five people in a small, confined vessel is going to be very challenging and potentially creating a poisonous environment for the crew members,” Olivas told CNN’s Victor Blackwell.

In case of an emergency, the submersible is equipped with basic emergency medical supplies and pilots have basic first aid training, according to OceanGate Expeditions’ website.

The company calls its clients “mission specialists,” who are trained as crew members in a variety of different roles, including communicating with the topside tracking team, taking sonar scans and opening and closing the vessel’s dome, the archived site says.

Clients do not need previous maritime experience to join as mission specialists, it adds.

“Every step possible is being taken to bring the five crew members back safely,” OceanGate in a statement on Monday said. “We are deeply grateful for the urgent and extensive assistance we are receiving from multiple government agencies and deep-sea companies as we seek to reestablish contact with the submersible.”

Deep sea-mapping company Magellan, known for its deep-sea imagery of the Titanic, got notice from the company running the Titanic expedition to mobilize early Monday “by all means necessary– time is of the essence,” Magellan Chairman David Thompson told CNN.

But Magellan needs aircraft that can take its deep-sea diving equipment to the search area – something they don’t have, and they had yet to hear back Tuesday from the US Air Force or UK Royal Airforce about whether they can offer Magellan the use of a plane, Thompson said.

    Search efforts grow as mission to rescue 5 aboard missing submersible races clock | CNN

    [ad_1]



    CNN
     — 

    The multinational search efforts for a submersible with five people onboard that disappeared Sunday while diving to view the Titanic’s resting place grew Tuesday as more ships and aircraft joined the mission to find the mariners before their oxygen runs out.

    A spokesperson for the US Navy said the military branch is sending subject matter experts and a “Flyaway Deep Ocean Salvage System” to help in the rescue mission for the commercial submersible, which disappeared Sunday morning and as of Tuesday night, had just over 30 hours of oxygen left.

    The system has the capacity to lift and recover large, bulky and heavy undersea objects, like the small submersible.

    The equipment and personnel were expected to arrive at St. John’s, Newfoundland, by Tuesday night, the spokesperson said.

    The US Coast Guard and the Royal Canadian Air Force are also deploying more aircraft and vessels to aid in the search for the 21-foot submersible. The fleet of assets joining the operation include a Canadian pipe-laying vessel with underwater capabilities, along with other vessels and aircraft.

    OceanGate Expeditions says the submersible, known as “Titan,” begins each trip with 96 hours of life support on the vessel. That is “a short amount of time,” said retired Capt. Bobbie Scholley, a former US Navy diver.

    “The hard part is finding the submersible. And once they find the submersible, there are all sorts of situations of how to get that submersible to the surface, and rescue the crew,” Scholley said.

    The international search and rescue operation is “doing everything possible” as part of a “complex search effort” but has so far “not yielded any results,” US Coast Guard Capt. Jamie Frederick told reporters Tuesday at a 1 p.m. ET news conference. The “unique” and “challenging” search effort has brought together “our nations’ best experts,” he said.

    At the time, Frederick estimated the vessel was down to 40 hours of oxygen – and officials do not know whether that’s enough time to rescue those onboard.

    “What I will tell you is, we will do everything in our power to effect a rescue,” he said in response to a question about the oxygen time limit from CNN.

    If searchers locate the submersible deep in the ocean, the mission to recover the craft and any onboard survivors will be complex.

    “There’s very few assets in the world that can go down that deep,” said retired Capt. Chip McCord, whose 30 years of US Navy experience includes overseeing several salvage operations.

    Because of the depth of the ocean floor, a search craft would have to “go up and down like an elevator” rather than cruise the bottom of the sea, he added.

    Searchers have taken the mission below sea level after scouring an area of the ocean’s surface about the size of Connecticut, US Coast Guard District 1 Rear Admiral John Mauger said Tuesday morning. “We now have underwater search capability on scene, and so we’re going to be using that to see if we can locate the submersible in the water,” he told CNN.

    The search zone covers an area about 900 miles east of Cape Cod, Massachusetts, and 13,000 feet deep, Mauger said Monday afternoon. “We are deploying all available assets to make sure that we can locate the craft and rescue the people onboard,” he told reporters.

    The submersible known as “Titan” – roughly the size of a minivan – was carrying one pilot and four “mission specialists” when it lost contact with its mother ship about 1 hour and 45 minutes into its descent, authorities said.

    The submersible is operated by OceanGate Expeditions, a company that organizes a journey to the ocean floor for a price of $250,000, according to an archived version of its website.

    The 23,000-pound Titan is made of highly engineered carbon fiber and titanium and is equipped with repurposed everyday items, including a video game controller used to steer.

    The expedition reflects the ongoing fascination with the Titanic’s wreckage more than a century after it hit an iceberg and sank on its maiden voyage, killing more than 1,500 people. The journey is also part of the growing business of wealthy adventure tourism, along with the space flights of Blue Origin or the rise of guided tours to Mount Everest.

    OceanGate CEO and founder Stockton Rush is among the five onboard, according to a source with knowledge of the mission plan.

    The others are British businessman Hamish Harding; Pakistani billionaire Shahzada Dawood and his son, Sulaiman Dawood; and French diver Paul-Henri Nargeolet, according to CNN reporting.

    OceanGate did not immediately respond to CNN’s request for comment about Rush being aboard.

    OceanGate in a statement on Monday said “every step possible is being taken to bring the five crew members back safely. We are deeply grateful for the urgent and extensive assistance we are receiving from multiple government agencies and deep-sea companies as we seek to reestablish contact with the submersible.”

    In 2018, the Manned Underwater Vehicles committee of the Marine Technology Society penned a letter to Rush, expressing concern over what they referred to as OceanGate’s “experimental approach” of the Titan and its planned expedition to the site of the Titanic wreckage, the New York Times reports.

    “Our apprehension is that the current experimental approach adopted by Oceangate could result in negative outcomes, (from minor to catastrophic) that would have serious consequences for everyone in the industry,” the letter – which was obtained by the Times – reads, in part.

    Specifically, the letter expressed concern over the company’s compliance with a maritime risk assessment certification known as DNV-GL.

    “Your marketing material advertises that the TITAN design will meet or exceed the DNV-GL safety standards, yet it does not appear that Oceangate has the intention of following DNV-GL classrules,” the letter says. “Your representation is, at minimum, misleading to the public and breaches an industry-wide professional code of conduct we all endeavor to uphold.”

    OceanGate has not responded to a request for comment on the letter.

    The effort to locate those on board, meanwhile, has grown by the day. The Coast Guard is searching with aerial and water surface craft, and the Canadian Armed Forces is also deploying aircraft to assist in the search, a spokesperson told CNN.

    The Canadian research vessel Polar Prince, which took the submersible to the wreckage site, is assisting search and rescue efforts, a spokesperson for its co-owner Horizon Maritime told CNN.

    Officials involved in the search have not publicly named those aboard the submersible, but social media posts and friends and family have identified them.

    Action Aviation, an aircraft brokerage based in the United Arab Emirates, in a statement on Tuesday confirmed Harding, its chairman, is on board.

    “Both the Harding Family and the team at Action Aviation are very grateful for all the kind messages of concern and support from our friends and colleagues,” the statement said. “We are thankful for the continued efforts of the authorities and companies that have stepped in to aid in the rescue efforts. We put great faith and trust in their expertise.”

    Harding has an extensive record of adventures: In 2019 he took part in a flight crew that broke the world record for the fastest circumnavigation of the globe via both poles, and in 2020 he became one of the first people to dive to Challenger Deep in the Pacific Ocean, widely believed to be the deepest point in the world’s oceans.

    And last year, he paid an undisclosed sum of money for one of the seats on Blue Origin’s space flight.

    The day before the vessel went missing, Harding wrote of the Titanic mission: “I am proud to finally announce that I joined OceanGate Expeditions for their RMS TITANIC Mission as a mission specialist on the sub going down to the Titanic.”

    A friend told CNN on Tuesday that Harding is “larger than life.”

    “He lives exploration. He is an explorer to the core of his soul,” fellow explorer Jannicke Mikkelsen said. “He has been to the bottom of planet earth in the Mariana Trench … he’s even been in space. We circumnavigated the planet together … the north and south pole, and set the world speed record.”

    Nargeolet was scheduled to be on Sunday’s dive with him, Harding said Saturday in a Facebook post:

    “The team on the sub has a couple of legendary explorers, some of which have done over 30 dives to the RMS Titanic since the 1980s including PH Nargeolet,” Harding wrote, according to CNN news partner CTV News.

    A friend of Nargeolet, Mathieu Johann, told CNN Tuesday the missing submariner is a “hero” and said, “I hope that, right to the end, like in the movies, he’ll reappear very quickly to reassure us all.”

    “What we’re going through right now is this interminable wait,” Johann said.

    Nargeolet is a Titanic expert who has taken the trip every year, completing more than 37 dives to the wreck, according to an archived version of OceanGate Expeditions’ website accessible via the Internet Archive’s Wayback Machine.

    “Something we always think about as explorers and scientists … we’ve always known something like this could happen and now it’s happened,” said David Gallo, a colleague of Nargeolet and the senior adviser for Strategic Initiatives at RMS Titanic Inc. “But we’re still pretty much in shock, the community is. I hope it has a good ending.”

    Further, Shahzada Dawood and his son Sulaiman Dawood, of Pakistan, “embarked on a journey to visit the remnants of the Titanic in the Atlantic Ocean,” their family said Tuesday in a statement. “As of now, contact has been lost with their submersible craft and there is limited information available,” the family said, adding they’re praying for their loved ones’ safe return.

    The incident has left the community of undersea explorers in shock, said David Gallo, who called Nargeolet his “closest colleague. “We’ve always known something like this could happen and now it’s happened … I hope it is a good ending,” Gallo, senior adviser for strategic initiatives at RMS Titanic Inc., told CNN.

    An undated photo shows the OceanGate Titan vessel.

    The OceanGate Expeditions trip began with a 400-nautical-mile journey from St. John’s, Newfoundland, to the Titanic wreck site. There, the submersible started its descent Sunday morning before losing contact with the Polar Prince, a converted ice breaker that was its mother ship.

    The last communication between the vessel and OceanGate staff at the surface came in at 11:47 a.m. The vessel was expected to resurface at 6:10 p.m. but did not do so, and authorities were notified at 6:35 p.m., according to Polar Prince co-owner Miawpukek Maritime Horizon Services.

    Chief Mi’sel Joe of Miawpukek First Nation, which co-owns the Polar Prince, got a call Sunday alerting him that the submersible was two hours overdue and still hadn’t surfaced and communication with it was lost, he said. At that point, requests for search and rescue had gone out, he said.

    “There’s a tremendous amount of concern,” Joe said. “I have anguish that people are going through this. I wish there was more I can do.”

    Unlike a submarine, a submersible needs a mother ship to launch it, has fewer power reserves and can’t stay underwater as long.

    A mother ship can communicate with a submersible “via text messages which are exchanged via a USBL (ultra-short baseline) acoustic system,” according to OceanGate Expeditions’ archived website. The submersible is required to communicate with the ship every 15 minutes or more frequently, if needed, the site says. That USBL system is the only communications link between the submersible and the surface, it adds.

    What we know about the timeline:

    Friday, June 16:

  • The Polar Prince departs St. John’s, NewfoundlandSaturday, June 17:
  • The Polar Prince arrives at the dive siteSunday, June 18:
  • 9 a.m.: The dive operations started
  • 11:47 a.m.: Last communication between vessel and OceanGate surface staff
  • 6:10 p.m.: Originally scheduled resurface time
  • 6:35 pm.: Authorities notified and response operation initiated
  • All times in Atlantic Daylight Time, which is 1.5 hours ahead of Eastern Time
  • Source: Miawpukek Maritime Horizon Services, which co-owns the Polar Prince
  • While Titan is made of carbon fiber and titanium, some parts are decidedly low-tech.

    “It is operated … by a gaming controller, what essentially looks like a PlayStation controller,” said CNN correspondent Gabe Cohen, who sat in Titan in 2018 while reporting on OceanGate Expeditions for CNN affiliate KOMO.

    Cohen was surprised by how simple some of the craft’s technology seemed, he said Tuesday on “CNN This Morning.”

    It’s a “tiny vessel, quite cramped and small,” Cohen said. “You have to sit inside of it, shoes off. It can only fit five people.”

    A Titanic dive takes about 10 hours from start to finish, including the two and a half hours it takes to reach the bottom, the website says. The company calls its clients “mission specialists,” who are trained as crew members in a variety of different roles, including communicating with the topside tracking team, taking sonar scans and opening and closing the vessel’s dome, the archived site says.

    Clients do not need previous maritime experience to join as mission specialists, it adds.

    In case of an emergency, the submersible is equipped with basic emergency medical supplies and pilots have basic first aid training, according to OceanGate Expeditions’ website.

    Everybody is “focused onboard here for our friends,” an expedition participant on the Polar Prince said Monday.

    “We have a situation that is now the part of a major Search and Rescue effort, being undertaken by major agencies,” Rory Golden said on Facebook after CNN contacted him. “That is where our focus is right now.”

    Hamish Harding posted an image of the submersible to his social media accounts on Saturday.

    Deep sea-mapping company Magellan, known for their one-of-a-kind deep sea imagery of the Titanic, is trying to get involved in the search and rescue efforts but a key transport issue is holding them back. Magellan Chairman David Thompson told CNN that his team is familiar with the site of the wreck and received written notice from OceanGate Expeditions to mobilize early Monday and help.

    However, they need an aircraft with the ability to transport their deep-sea diving equipment from the UK to Canada to launch their operation. Specifically, he said, they would require the use of a C-17 Globemaster III military jet.

    “We know the wreck site, we know the location, and the equipment we are trying to get picked up is the equipment we used to do that scanning of the Titanic,” Thompson said.

    Thompson said the US Air Force or UK Royal Airforce have not gotten back to Magellan letting them know if or when a plane can be procured for them to use to transport the equipment they need to Canada to embark on rescue efforts.

    Correction: An earlier version of this story incorrectly described Mathieu Johann’s relationship to Nargeolet. He is a friend.

  • Rescuers race against time to find missing submersible in Atlantic bound for Titanic wreckage site

    Rescuers race against time to find missing submersible in Atlantic bound for Titanic wreckage site

    [ad_1]

    Rescuers in a remote area of the Atlantic Ocean raced against time early Tuesday to find a missing submersible carrying five people on a mission to document the wreckage of the Titanic, the iconic ocean liner that sank more than a century ago.

    The submersible named the Titan, part of a mission by OceanGate Expeditions, carried a pilot, a renowned British adventurer, two members of an iconic Pakistani business family and another passenger. Authorities reported the vessel overdue Sunday night about 435 miles (700 kilometers) south of St. John’s, Newfoundland, according to Canada’s Joint Rescue Coordination Center.

    Every passing minute, however, puts the Titan’s crew at greater risk. The submersible had a 96-hour oxygen supply when it put to sea at roughly 6 a.m. Sunday, according to David Concannon, an adviser to OceanGate.

    “It is a remote area — and it is a challenge to conduct a search in that remote area,” said Rear Adm. John Mauger, a commander for the U.S. Coast Guard, which also is searching for the Titan. “But we are deploying all available assets to make sure we can locate the craft and rescue the people on board.”

    The Canadian research icebreaker Polar Prince, which was supporting the Titan, reportedly lost contact with the vessel about an hour and 45 minutes after it submerged. The Polar Prince will continue to do surface searches throughout the night and Canadian Boeing P-8 Poseidon reconnaissance aircraft will resume their surface and subsurface search in the morning, the U.S. Coast Guard said on Twitter. Two U.S. Lockheed C-130 Hercules aircraft also have conducted overflights.

    In an email to The Associated Press, Concannon said he was supposed to be on the dive but could not go. He said officials were working to get a remotely operated vehicle that can reach a depth of 3.7 miles (6 kilometers) to the site as soon as possible.

    OceanGate’s expeditions to the Titanic wreck site include archaeologists and marine biologists. The company also brings people who pay to come along, known as “mission specialists.” They take turns operating sonar equipment and performing other tasks in the five-person submersible.

    The Coast Guard said Monday that there was one pilot and four “mission specialists” aboard. However, OceanGate’s website suggests that the fifth person aboard may be a so-called “content expert” who guides the paying customers.

    OceanGate said its focus was on those aboard and their families.

    “We are deeply thankful for the extensive assistance we have received from several government agencies and deep sea companies in our efforts to reestablish contact with the submersible,” it said in a statement.

    British businessman Hamish Harding, who lives in Dubai in the United Arab Emirates, was one of the mission specialists, according to Action Aviation, a company for which Harding serves as chairman. The company’s managing director, Mark Butler, told the AP that the crew set out on Friday.

    “There is still plenty of time to facilitate a rescue mission, there is equipment on board for survival in this event,” Butler said. “We’re all hoping and praying he comes back safe and sound.”

    Harding is a billionaire adventurer who holds three Guinness World Records, including the longest duration at full ocean depth by a crewed vessel. In March 2021, he and ocean explorer Victor Vescovo dived to the lowest depth of the Mariana Trench. In June 2022, he went into space on Blue Origin’s New Shepard rocket.

    Harding was “looking forward to conducting research” at the Titanic site, said Richard Garriott de Cayeux, the president of The Explorers Club, a group to which Harding belonged.

    “We all join in the fervent hope that the submersible is located as quickly as possible,” he said in a statement.

    Also on board were Pakistani nationals Shahzada Dawood and his son Suleman, according to a family statement sent to the AP. The Dawoods belong to one of Pakistan’s most prominent families. Their eponymous firm invests across the country in agriculture, industries and the health sector.

    “We are very grateful for the concern being shown by our colleagues and friends and would like to request everyone to pray for their safety while granting the family privacy at this time,” the statement said. “The family is well looked after and are praying to Allah for the safe return of their family members.”

    Shahzada Dawood also is on the board of trustees for the California-based SETI Institute that searches for extraterrestrial intelligence.

    The expedition was OceanGate’s third annual voyage to chronicle the deterioration of Titanic, which struck an iceberg and sank in 1912, killing all but about 700 of the roughly 2,200 passengers and crew. Since the wreckage’s discovery in 1985, it has been slowly succumbing to metal-eating bacteria. Some have predicted the ship could vanish in a matter of decades as holes yawn in the hull and sections disintegrate.

    The initial group of tourists in 2021 paid $100,000 to $150,000 apiece to go on the trip. OceanGate’s website had described the “mission support fee” for the 2023 expedition as $250,000 a person.

    Unlike submarines that leave and return to port under their own power, submersibles require a ship to launch and recover them. OceanGate hired the Polar Prince to ferry dozens of people and the submersible craft to the North Atlantic wreck site. The submersible would make multiple dives in one expedition.

    The expedition was scheduled to depart from St. John’s, Newfoundland, in early May and finish up at the end of June, according to documents filed by the company in April with a U.S. District Court in Virginia that oversees Titanic matters.

    CBS journalist David Pogue, who went on the trip last year, noted his vessel got turned around looking for the Titanic.

    “There’s no GPS underwater, so the surface ship is supposed to guide the sub to the shipwreck by sending text messages,” Pogue said in a segment aired on CBS Sunday Morning. “But on this dive, communications somehow broke down. The sub never found the wreck.”

    The submersible, named Titan, is capable of diving 2.4 miles (4 kilometers) “with a comfortable safety margin,” OceanGate said in its court filing.

    It weighs 20,000 pounds (9,072 kilograms) in the air, but is ballasted to be neutrally buoyant once it reaches the seafloor, the company said.

    In a May 2021 court filing, OceanGate said the Titan had an “unparalleled safety feature” that assesses the integrity of the hull throughout every dive.

    During its expedition in 2022, OceanGate reported that the submersible had a battery issue on its first dive, and had to be manually attached to its lifting platform, according to a November court filing. More missions, however, followed. The company reported that 28 people visited the wreck site last year.

    Experts said Monday that rescuers face steep challenges.

    Alistair Greig, a professor of marine engineering at University College London, said submersibles typically have a drop weight, which is “a mass they can release in the case of an emergency to bring them up to the surface using buoyancy.”

    “If there was a power failure and/or communication failure, this might have happened, and the submersible would then be bobbing about on the surface waiting to be found,” Greig said.

    Another scenario is a leak in the pressure hull, in which case the prognosis is not good, he said.

    “If it has gone down to the seabed and can’t get back up under its own power, options are very limited,” Greig said. “While the submersible might still be intact, if it is beyond the continental shelf, there are very few vessels that can get that deep, and certainly not divers.”

    Even if they could go that deep, he doubts they could attach to the hatch of OceanGate’s submersible.

  • United Nations adopts high seas treaty, the first-ever pact to govern and protect international waters

    United Nations adopts high seas treaty, the first-ever pact to govern and protect international waters

    [ad_1]

    United Nations — The United Nations on Monday adopted the first-ever legally binding international treaty governing the high seas. Known as the Biodiversity Beyond National Jurisdiction Treaty (BBNJ), but widely referred to as the High Seas Treaty, the measure approved by the 193 U.N. member states imposes rules aimed at protecting the environment and heading off disputes over natural resources, shipping and other matters in waters beyond any country’s national jurisdiction.

    Until now, there has never been any international law governing the high seas, so many individuals and organizations hope the U.N.’s adoption of the measure will mark a clear turning point for vast stretches of the planet where conservation efforts have long struggled in a sort of wild west of exploration, overfishing, oil exploration and deep-sea mining.

    “You have delivered,” U.N. Secretary-General Antonio Guterres told the member nations Monday upon the treaty’s adoption. “And you have done so at a critical time.”

    What’s the point of a High Seas Treaty?

    “To prevent a cascading of species extinctions, last year we universally agreed to the Global Biodiversity Framework’s target of protecting 30% of the planet’s land and sea by 2030,” Peter Thomson, the U.N. Secretary-General’s Special Envoy for the Oceans, told CBS News. “To reach that target, we’ll have to establish Marine Protected Areas in the High Seas, and happily the BBNJ Treaty will give us the legal means to do that.”

    “Roughly two thirds of the Earth’s oceans lie beyond national boundaries in an area known as the ‘high seas’ — yet only about 1% of that largely unexplored expanse has been protected. This year, nearly 200 nations finally agreed on the first treaty to protect the high seas,” the Conservation International organization said.


    “Oceans Give, Oceans Take”: Their role in climate change

    07:01

    The only treaty that came close previously was the U.N. Convention on the Law of the Sea, which came into force three decades ago. But that treaty regulated seas within country’s territorial waters and exclusive economic zones, leaving nearly half the planet’s surface and two-thirds of the ocean unregulated — particularly when it comes to protecting biodiversity. The new high seas treaty was agreed to under the authority of the previous Law of the Seas Treaty.

    “The high seas are among the last truly wild places on earth,” said Monica Medina, the Assistant Secretary of the U.S. Bureau of Oceans and International Environmental and Scientific Affairs, who was the Biden administration’s chief negotiator and supporter of the treaty.

    “It is often said that the ocean is too big to fail. That is simply not true,” Medina said. “The ocean is more fragile than most people understand. It is also more essential. It provides the oxygen we breathe and food for tens of millions of people.”

    Nichola Clark, who works with the Pew Charitable Trusts’ ocean governance project, told CBS News the treaty was “critical for our climate, as the world’s oceans play “an important role in regulating our climate – absorbing carbon dioxide and excess heat from the atmosphere, regulating temperatures, and driving our global weather patterns.”  

    So, what’s in the treaty? Here are the key points:

    • MPAs: The treaty establishes a framework for “Marine Protected Areas” — beyond the ones already within national territorial waters — to counter biodiversity loss and degradation of ecosystems of the ocean caused by the impact of climate change, including warming and acidification of oceans, as well as plastics, pollutants and overfishing.
    • It establishes standards and guidelines to determine the environmental impacts of high seas activities, including their impact on marine life and ecosystems. It requires signatory countries to present an assessment of pollution or other impacts of their proposed activities on the high seas, such as deep-sea mining.
    • The treaty creates a Conference of Parties (COP) to monitor and enforce compliance with the treaty’s terms, which will include a scientific advisory board.
    • It creates a mechanism for the transfer of marine technology to developing countries to ensure equitable sharing of benefits and resources from the high seas, including materials that could prove ground-breaking in medical and nutrition science.

    Final hurdle: National ratifications

    There is a final hurdle — or 60, actually — that the new treaty must still clear: It will only go into effect 120 days after it is ratified by at least 60 U.N. member nations individually. In the U.S., that means Senate approval.

    Clark, of the Pew Charitable Trusts, told CBS News the hope was that the requisite 60 ratifications would be in-hand by the next U.N. Ocean Conference, set to convene in the summer of 2025.

    “As with all treaties, ratification is the key to bringing it into force, and only then can we implement the benefits accruing. All parties should work towards this being achieved by the time of the next UN Ocean Conference, June 2025, in Nice, France,” the U.N.’s Thomson told CBS News.

    But in a sign of the work still to come, Russia’s delegate Sergey Leonidchenko on Monday made it clear that his country, “distances itself from the consensus on the text of the agreement prepared by the conference.”

    While Moscow did not seek to block adoption of the treaty by the U.N., his remarks made it clear that Russia could not yet be counted on for one of the 60 required ratifications, calling the international treaty as written, “unacceptable.”

  • As rising oceans threaten NYC, study documents another risk: The city is sinking

    As rising oceans threaten NYC, study documents another risk: The city is sinking

    [ad_1]

    NEW YORK — If rising oceans aren’t worry enough, add this to the risks New York City faces: The metropolis is slowly sinking under the weight of its skyscrapers, homes, asphalt and humanity itself.

    New research estimates the city’s landmass is sinking at an average rate of 1 to 2 millimeters per year, something referred to as “subsidence.”

    That natural process happens everywhere as ground is compressed, but the study published this month in the journal Earth’s Future sought to estimate how the massive weight of the city itself is hurrying things along.

    More than 1 million buildings are spread across the city’s five boroughs. The research team calculated that all those structures add up to about 1.7 trillion tons (1.5 trillion metric tons) of concrete, metal and glass — about the mass of 4,700 Empire State buildings — pressing down on the Earth.

    The rate of compression varies throughout the city. Midtown Manhattan’s skyscrapers are largely built on rock, which compresses very little, while some parts of Brooklyn, Queens and downtown Manhattan are on looser soil and sinking faster, the study revealed.

    While the process is slow, lead researcher Tom Parsons of the U.S. Geological Survey said parts of the city will eventually be under water.

    “It’s inevitable. The ground is going down, and the water’s coming up. At some point, those two levels will meet,” said Parsons, whose job is to forecast hazardous events from earthquakes and tsunamis to incremental shifts of the ground below us.

    But no need to invest in life preservers just yet, Parsons assured.

    The study merely notes buildings themselves are contributing, albeit incrementally, to the shifting landscape, he said. Parsons and his team of researchers reached their conclusions using satellite imaging, data modeling and a lot of mathematical assumptions.

    It will take hundreds of years — precisely when is unclear — before New York becomes America’s version of Venice, which is famously sinking into the Adriatic Sea.

    But parts of the city are more at risk.

    “There’s a lot of weight there, a lot of people there,” Parsons said, referring specifically to Manhattan. “The average elevation in the southern part of the island is only 1 or 2 meters (3.2 or 6.5 feet) above sea level — it is very close to the waterline, and so it is a deep concern.”

    Because the ocean is rising at a similar rate as the land is sinking, the Earth’s changing climate could accelerate the timeline for parts of the city to disappear under water.

    “It doesn’t mean that we should stop building buildings. It doesn’t mean that the buildings are themselves the sole cause of this. There are a lot of factors,” Parsons said. “The purpose was to point this out in advance before it becomes a bigger problem.”

    Already, New York City is at risk of flooding because of massive storms that can cause the ocean to swell inland or inundate neighborhoods with torrential rain.

    The resulting flooding could have destructive and deadly consequences, as demonstrated by Superstorm Sandy a decade ago and the still-potent remnants of Hurricane Ida two years ago.

    “From a scientific perspective, this is an important study,” said Andrew Kruczkiewicz, a senior researcher at Columbia University’s Climate School, who was not involved in the research.

    Its findings could help inform policy makers as they draft ongoing plans to combat, or at least forestall, the rising tides.

    “We can’t sit around and wait for a critical threshold of sea level rise to occur,” he said, “because waiting could mean we would be missing out on taking anticipatory action and preparedness measures.”

    New Yorkers such as Tracy Miles can be incredulous at first.

    “I think it’s a made-up story,” Miles said. He thought again while looking at sailboats bobbing in the water edging downtown Manhattan. “We do have an excessive amount of skyscrapers, apartment buildings, corporate offices and retail spaces.”

    New York City isn’t the only place sinking. San Francisco also is putting considerable pressure on the ground and the region’s active earthquake faults. In Indonesia, the government is preparing for a possible retreat from Jakarta, which is sinking into the Java Sea, for a new capital being constructed on the higher ground of an entirely different island.

    If you think that life at sea is like the movie franchise “Pirates of the Caribbean,” think again.

    The movies, which feature ambushes, looting and a drunken captain, are far from real life, according to shipping veteran Ralph Juhl.

    “That is, of course, a lot of bollocks,” Juhl told CNBC by phone.

    For starters, the consumption of alcohol is banned on many ships.

    But there is one similarity with the movie, Juhl said: the code of conduct between seafarers. In the franchise, the Pirate’s Code was chronicled in a book kept by character Captain Teague, and loosely followed by some.

    For those who sail for a living, there is a similar type of agreement, Juhl said.

    “Seafarers, no matter where they come from — India, Ukraine, Denmark, the Philippines — there is this conduct of how you behave on a ship … You can actually endanger both yourself and all of your colleagues if you are not playing that social game, being on board the ship. So, you take responsibility, you follow authority,” Juhl said.

    Juhl, an executive vice-president at oil tanker firm Hafnia, has worked in the industry for several decades, starting as an ordinary seaman — the lowest rank of sailor — in 1983.

    “When you as a seafarer [go] on board … you are a contribution to the society and you have to fit in … there is this code of the high seas,” he added.

    A captain’s life

    “Pirates of the Caribbean” is a seafaring stereotype familiar to Hafnia’s DSA Dixon, who has been a captain for five years. Dixon — who sails vessels known as product tankers, which transport both refined and unrefined petroleum products around the world — had to convince his parents-in-law that his role was nothing like the movie, he told CNBC by phone.

    “A lot of people have a very different representation of a seafarer, looking at Pirates of the Caribbean,” he said.

    Captain DSA Dixon (in black) says he invents games to keep his crew’s morale up during months at sea.

    Dixon might be captaining a ship such as the huge Hafnia Rhine, which is about 230 meters long by 33 meters wide, with a capacity of more than 76,000 deadweight tons — a measure that includes the oil cargo, plus fuel, food, water and crew members, but not the weight of the ship itself.

    Where the ship goes depends on where the demand for oil is and Dixon has sailed to every continent bar Antarctica, he said.

    Dixon aims to keep to a schedule of three months at sea followed by three months at home in Mumbai, India, he said, and he started his most recent voyage on the Mississippi River in the U.S., sailing to Brazil and going on to Saudi Arabia via Gibraltar and the Suez Canal, before returning to Brazil.

    The greatest part of my job is I’ve seen things that an average human being might not.

    Compared to someone working an office job, Dixon said he spends more time with his wife and six-year-old son, as when he is at home he’s “completely” there. “I love this part of my life, because when I go back home, I’m Santa Claus,” he said. “It doesn’t get stagnated at any point – when it’s about to get stagnated, I’m back at sea.”

    High days and holidays

    Aside from navigation, Dixon said the most important part of his job is to keep the crew in good spirits, as they spend months at sea together.

    “We have at times, 20, 25 people on board, they’re all different nationalities, different cultures, different languages … our ship is as good as the people on it,” Dixon said.

    There’s no fixed daily routine, Dixon added. “There’s no one way to describe life on board. It’s challenging of course, but the challenge keeps you motivated all the time,” he said.

    Along with navigation and managing the crew, Dixon might be talking to officials who come aboard when the ship is docked or coming up with ways to celebrate religious festivals.

    “Irrespective of nationality, or religion, people celebrate each other’s events or festivals,” Dixon said. “I even invent something like a treasure hunt on board. The ship is massive, I divide [crew] into teams … and let them find their own way,” Dixon added.

    These games might sound “kiddish,” but they serve an important purpose, Dixon said. “These are grown-up men, some might be 50 years-old, and they’re doing this, but it’s the way to bond … we need to socialize and a happy ship is always an excellent vessel,” Dixon said.

    Dixon makes sure the crew take Sundays off, spending it as they choose: perhaps playing PlayStation, chatting or sleeping. “I make sure there’s an excellent lunch,” Dixon added.

    Traveling across oceans means getting to experience some of the world’s natural spectacles, with Dixon seeing the light phenomenon aurora borealis — also known as the northern lights — while sailing near Norway.

    “The only regret I have is what I see I’m not able to share it, I want my family to see [things] at that very point, at that very moment, a photograph won’t capture it,” Dixon said. How did he feel seeing the lights? “You feel complete, I will say. You feel abundant,” he said.

    “The greatest part of my job is I’ve seen things that an average human being might not,” he added.

    Rough waters

    Alongside enjoying scenes of wonder, life as a seafarer can be tough.

    Hafnia Chief Engineer Dmytro Lifarenko is from Ukraine and was at home when Russia invaded the country in February 2022, fleeing with his wife and children across Europe to Valencia in Spain.

    “I don’t know how I would handle … knowing that the bombs were there and I’m on board,” he told CNBC by phone, speculating about how he would have felt if he had been at sea when war broke out.

    While his most recent voyage was five months long — sailing from Singapore to France and then Australia — he has recently taken extended leave to settle his family in their new home.

    “I miss my family a lot during the voyage,” Lifarenko said — he and his wife have three children: a daughter of six months, six-year-old son and a 12-year-old daughter.

    “Being two parents for three kids, this is fine. Being [effectively] a single mom for our kids, that’s very difficult … to be honest, this is the worst part of the job.”

    This is something Juhl is sympathetic to: “That’s a big ‘uncomfort’ for many seafarers, that they are now so involved in their family [while at sea], even though they can’t do anything about it,” he said.

    Executive vice president, Hafnia

    During the Covid-19 pandemic in 2020, Lifarenko spent about six months onboard, which is longer than his usual voyage. He said guided meditations sent to him by Hafnia were useful to deal with an uncertain situation.

    “You keep thinking about the things that you actually cannot change, and that’s quite close to depression, but this [was] like a helpful hand,” he said.

    But, despite some downsides, Lifarenko said he loves his job because of its variety. “You cannot say what is your routine, because the routine part is quite small. Most of the time, you are solving some situation, which requires you to use your brain, and you’re thinking, how to fix this … or how can we maintain this in a better way,” he said.

    He has also enjoyed seeing the natural world while onboard, including spotting whales and sailing close to the volcanic Canary Islands.

    Future sailors

    Juhl spent more than a decade as a seafarer, starting at age 16 and sailing to places such as Honduras and South Korea, and becoming a navigator on chemical carrier ships before captaining ferries. He came onshore in 1997 and is now responsible for Hafnia’s technical operations. He described those onboard as “working their butts off.”

    “They never go ashore anymore, there are terminals far away from cities and so on. So, this romantic life and impression of seafarers, it is pretty much gone. It’s hard work,” he said.

    This means attracting the next generation of crew is potentially tougher. “It’s a lonely life from time to time. And today you cannot offer young people loneliness,” he said.

    Juhl wants to encourage more women to become seafarers and Hafnia is working on a pilot program to operate two ships where half the crew are female, to understand how the culture onboard might change, both positively and negatively, and how to solve that.

    However, issues remain: Authorities in countries where women are discriminated against might not deal with female captains, for example, so Hafnia has had to temporarily assign a male captain for port stays in such places, Juhl said.

    There has been internet access on board tankers for just a couple of years, Juhl added, and he wants to get creative about what might be possible as technology involves. 

    He’s especially keen for sailors to be able to communicate with their families at home, he said.

    “Hopefully we can soon make holograms where the captain can go to his cabin with his supper, and then he can open his hologram and he can sit and eat with his wife … we have to think that way,” Juhl said. And new technology will mean seafarers need different skills. “The boiler suit dressed man with a big spanner — it’s not the sailor that we’ll need in the future,” he said.

    CNN
     — 

    It all seems so daunting: plastics in the ocean, dying coral reefs, entire species being wiped out – but don’t click away in despair!

    There really are things everyone can do to help make the ocean cleaner and keep our environment healthier.

    Here are some easy (or mostly easy) life changes that have a big impact on our environment.

    Whenever you eat fish, make sure you choose a sustainable variety that isn’t endangered.

    The Monterey Bay Aquarium’s “Seafood Watch” program has online guides detailing which fish are your best bets. All of these directories, broken up by region, can be downloaded into a printable pocket guide – so if you’re a seafood lover, it’s a handy resource to keep nearby.

    The most consumed seafoods in the US are shrimp, salmon and tuna. If those are among your go-to choices, some more environmentally responsible options to look for include shrimp from the US or Canada; salmon caught in the US Pacific or Canada; and canned tuna labeled “pole-caught,” “pole-and-line-caught,” or “troll-caught.”

    How your fish is caught is important. You want to make sure you’re not consuming fish caught in nets that are notorious for trapping “bycatch” – turtles, seabirds and whales often get caught in those lines and die.

    And since whales do an excellent job trapping planet-warming carbon emissions – even better than trees – keeping them in the ocean helps us all.

    Trash piles up along the bank of the San Gabriel River near the Pacific Ocean in Seal Beach, California. Rains sent the trash flowing down river from miles inland.

    This is a big one…and one of the worst problems facing the ocean, landfills and even our bodies!

    Jennifer Savage of Surfrider Foundation suggests supporting businesses that avoid single-use plastics.

    If your favorite restaurant still uses plastics, she tells diners to refuse the plastic forks and gently suggest the management move to a more sustainable takeaway option (like bamboo utensils and paper containers and straws) or – even better – go with washable plates and cutlery.

    “It saves money, too. If they’re spending all this money buying single-use plastic, a small investment in a dishwasher and reusable cutlery will save money in the long run.”

    Also, she says, consumers are realizing they prefer the less-disposable options.

    “People love it, people are so much happier. Think about how much better it feels to have a meal with metal utensils and a real plate.”

    As consumers begin to worry about things like microplastics making their way into their bodies, this is a “no-brainer” for restaurants, she says.

    “They found plastic in our bodies…people don’t want to eat off plastic plates with plastic utensils.”

    Surfrider Foundation even has a helpful online guide, highlighting ocean-friendly restaurants.

    Discarded plastic and other debris overflow from a Los Angeles trash bin. Surfrider Foundation reports less than 7% of plastic gets recycled in the US.

    It’s important to realize that most plastic doesn’t get recycled, according to Savage. She says the US rate of plastic recycling is only about 5% to 6%.

    The number system on the bottom of plastic items are not a guarantee they will be recycled. Things marked 1 and 2 — and on rare occasion, 5 — are your best bets, experts told CNN, depending on what your municipality can handle.

    “Things that have a number on them … that’s just a fallacy. That stuff just gets sorted out and put into the landfill,” Savage says. Ditto for that “chasing arrow” symbol you see on the bottom of many plastic containers, she says. Most of it still isn’t recyclable.

    Some states, including California, are starting to crack down on that misleading labeling and aren’t allowing the symbol to appear on plastic that isn’t recyclable.

    So whenever you can: skip single-use plastic and Styrofoam. Support businesses that are part of the solution. And talk to your representatives about phasing it out.

    The beach at Big Sur, California.

    Picking up trash on the beach won’t solve the problem on its own, but it is really important, says Savage.

    “At that moment in time, you’re going to have a cleaner beach. You will have less plastic in your environment. Cleaning it up and leaving it better than you found it makes you feel good.”

    And that “feeling good” often leads to activism. “Next thing you know, they’re going to city council meetings, contacting their representatives.”

    Another bonus of participating in a beach clean-up? It allows organizations to gather data about the most common items that end up as beach litter.

    “In California, you don’t see as many single-use plastic bags, so you don’t see them [on the beach as often] anymore. It helps people to see what the biggest problems are. Whether it’s plastic chip bags, or cigarette butts, or whatever.”

    Cosmetic chemist Autumn Blum is an avid diver and shark lover who produces ocean-friendly sunscreens.

    Autumn Blum is a cosmetic chemist by day, and a shark-obsessed scuba diver on the weekends.

    Ingredients you should avoid in sunscreens

  • Avobenzone
  • Benzophenones/oxybenzone
  • Butyloctyl salicylate
  • Clear or nano zinc/nano particles
  • Cylcopentasiloxane/cyclomethicone
  • Ecamsule
  • Formaldehyde, diazolidinyl urea, quaternium-15, DMDM hydantoin and hydroxymethylglycinate
  • Methylisothiazolinone
  • Microplastic
  • Octinoxate/octyl methozycinnamate
  • Padimate O
  • Parabens
  • Sodium lauryl and laureth sulfate (SLS/SLES)

  • She spent years formulating skin products for other companies before striking out on her own to create a mineral sunscreen business. Her inspiration? Seeing a group of snorkelers surrounded by a circle of oily film on the water, formed by the chemical sunscreens they had slathered on. She was horrified, knowing the chemicals were deadly for coral and many fish.

    “There are so many things that impact our waters. Something that we use on our bodies should not be one of them. Period,” says Blum. “That’s an easy piece that we can change to make a positive impact.”

    Blum says recent chemical sunscreen bans are already making a difference in places like Hawaii, with reefs coming back to life. She’s also encouraged by efforts to renew coral reefs via coral planting.

    There’s still no mutually agreed-upon term to describe what’s “reef-safe,” so what you really need to do is avoid certain ingredients that are known to be harmful, Blum says.

    Avoid microbeads

    Blum also encourages consumers to make sure they don’t buy products that contain microbeads.

    After you wash them off your face or body, those microbeads go down the drain, pass right through your local wastewater plant, and dump into the ocean. From there, they can be eaten by fish.

    Humans then eat the fish that have eaten the microbeads…and that’s another way we end up with microplastics in our bodies.

    Avoid face wash with plastic microbeads.

    Shark-friendly moisturizer

    Many new moisturizers are touting “squalane” as their new miracle ingredient.

    “Squalane is considered a bio-mimic ingredient, which means your body recognizes it,” Blum tells CNN.

    It is a common ingredient in sunscreens, cosmetics, and high-end skin products. “The unfortunate thing about squalane is that it’s frequently obtained from shark livers,” says Blum.

    Many species of sharks are facing extinction, and several of those species are considered “critically endangered.”

    Plant-based squalanes work just as well as shark-based ones, Blum says. So when reading your ingredient label, make sure it says “vegan squalane” or “plant-based squalane.” Otherwise, advises Blum, assume it comes from sharks.

    Vera Meyer, a scientist at the Berlin Institute of Biotechnology, holds a vessel made of scale sponge. The institute hopes to produce clothing, packaging and building material from fungal cultures.

    Now for the good news: Materials are being developed that could revolutionize all our packaging, Blum says.

    Mycelium, made from mushrooms, performs a lot like current plastics.

    Meanwhile, researchers at Yale have discovered a separate fungus with tantalizing abilities to break down polyurethane. It will be awhile, Blum says, but “really cool” technology based on plastic-eating mushrooms could be in our future.

    “It’s not commercial-ready, but it’s on the horizon,” she says.

    So forget “The Last of Us.” The mushrooms may save us all.

  • Study says warming may push more hurricanes toward US coasts

    Study says warming may push more hurricanes toward US coasts

    [ad_1]

    Changes in air patterns as the world warms will likely push more and nastier hurricanes up against the United States’ east and Gulf coasts, especially in Florida, a new study said.

    While other studies have projected how human-caused climate change will probably alter the frequency, strength and moisture of tropical storms, the study in Friday’s journal Science Advances focuses on the crucial aspect of where hurricanes are going.

    It’s all about projected changes in steering currents, said study lead author Karthik Balaguru, a Pacific Northwest National Laboratory climate scientist.

    “Along every coast they’re kind of pushing the storms closer to the U.S.,” Balaguru said. The steering currents move from south to north along the Gulf of Mexico; on the East Coast, the normal west-to-east steering is lessened considerably and can be more east-to-west, he said.

    Overall, in a worst-case warming scenario, the number of times a storm hits parts of the U.S. coast in general will probably increase by one-third by the end of the century, the study said, based on sophisticated climate and hurricane simulations, including a system researchers developed.

    The central and southern Florida Peninsula, which juts out in the Atlantic, is projected to get even more of an increase in hurricanes hitting the coast, the study said.

    Climate scientists disagree on how useful it is to focus on the worst-case scenario as the new study does because many calculations show the world has slowed its increase in carbon pollution. Balaguru said because his study looks more at steering changes than strength, the levels of warming aren’t as big a factor.

    The study projects changes in air currents traced to warming in the equatorial eastern Pacific Ocean, just off the coast of South America. Climate change is warming different parts of the world at different rates, and models show the eastern Pacific area warming more quickly, Balaguru said.

    That extra warming sets things in motion through Rossby waves, according to the study — atmospheric waves that move west to east and are connected to changes in temperature or pressure, like the jet stream or polar vortex events.

    “I like to explain it to my students like a rock being dropped in a smooth pond,” said University of Albany atmospheric scientist Kristen Corbosiero, who wasn’t part of the study. “The heating is the rock and Rossby waves are the waves radiating away from the heating which disturbs the atmosphere’s balance.”

    The wave ripples trigger a counterclockwise circulation in the Gulf of Mexico, which bring winds blowing from east to west in the eastern Atlantic and south to north in the Gulf of Mexico, Corbosiero and Balaguru said.

    It also reduces wind shear — which is the difference in speed and direction of winds at high and low altitudes — the study said. Wind shear often decapitates hurricanes and makes it harder for nascent storms to develop.

    Less wind shear means stronger storms, Balaguru said.

    Overall, the steering current and wind shear changes increase the risk to the United States, Corbosiero said in an email.

    Corbosiero and two other outside scientists said the study makes sense, but has limits and is missing some factors.

    It doesn’t factor in where storms are born, which is important, and the study assumes a global trend toward more El Nino events, said Jhordanne Jones, an atmospheric scientist at the National Center for Atmospheric Research and Purdue University’s Climate Extreme Weather Lab. Most climate simulations project more El Ninos, which is a natural warming of the central Pacific that alters weather worldwide and dampens Atlantic hurricane activity. But recent observations “suggest a more La Nina- like state,” she said.

  • “World’s deepest fish” caught on camera for first time by scientists — over 27,000 feet below the surface

    “World’s deepest fish” caught on camera for first time by scientists — over 27,000 feet below the surface

    [ad_1]

    A massive research initiative to explore deep-sea creatures brought new discoveries to light in the northern Pacific Ocean last year, when scientists filmed and captured three fish at depths never recorded before.

    As part of a 10-year collaborative study between the University of Western Australia and the Tokyo University of Marine Science and Technology, scientists used baited robotic cameras to film a young snailfish at about 8,300 meters below the surface, the Australian university announced on Monday. The school deemed the record-breaking discovery the “world’s deepest fish.”

    The milestone was announced after a two-month expedition that specifically focused on the deep-sea fish populations in three trenches located near Japan. The Japan, Izu-Ogasawara and Ryukyu trenches stretch 8,000 meters, 9,300 meters and 7,300 meters respectively below the surface of the northern Pacific.

    Snailfish are tadpole-like and can only grow to about 12 inches long. They are found in oceans across the world, with some species inhabiting relatively shallow waters. The snailfish discovered 8,300 meters down — which is more than 27,000 feet, or five miles, deep — belongs to an unknown species, scientists said. 

    They found and filmed the fish last September in the Izu-Ogasawara trench south of Japan, setting a world record for the deepest fish ever recorded on video. The footage was released on Sunday, and shows the snailfish, which scientists described as a very small juvenile, swimming on its own just above the ocean floor.

    This particular type of snailfish belongs to the Pseudoliparis family and had previously been seen about 7,700 meters below the surface of the ocean in 2008, according to the University of Western Australia. 

    Video footage released over the weekend also shows two snailfish found and caught during the same research expedition. At 8,022 meters down, in another deep trench off Japan, the pair of fish captured in traps marked scientists’ deepest catch on record.

    “The Japanese trenches were incredible places to explore; they are so rich in life, even all the way at the bottom,” said Alan Jamieson, a professor at the University of Western Australia who led the expedition, in a statement.

    “We have spent over 15 years researching these deep snailfish,” Jamieson added. “There is so much more to them than simply the depth, but the maximum depth they can survive is truly astonishing.”

    The professor said that scientists found snailfish “at increasingly deeper depths just creeping over that 8,000m mark in fewer and fewer numbers” in other areas, like the Mariana Trench — the world’s deepest — which is in the western Pacific Ocean closer to Guam. But Jamieson noted that the population explored around Japan was especially “abundant.”

    “The real take-home message for me, is not necessarily that they are living at 8,336m,” said Jamieson, “but rather we have enough information on this environment to have predicted that these trenches would be where the deepest fish would be, in fact until this expedition, no one had ever seen nor collected a single fish from this entire trench.”

    Crucial Antarctic ocean circulation heading for collapse if planet-warming pollution remains high, scientists warn | CNN

    Brisbane, Australia
    CNN
     — 

    Melting ice in the Antarctic is not just raising sea levels but slowing down the circulation of deep ocean water with vast implications for the global climate and for marine life, a new study warns.

    Led by scientists from the University of New South Wales and published Wednesday in the journal Nature, the peer-reviewed study modeled the impact of melting Antarctic ice on deep ocean currents that work to flush nutrients from the sea floor to fish near the surface.

    Three years of computer modeling found the Antarctic overturning circulation – also known as abyssal ocean overturning – is on track to slow 42% by 2050 if the world continues to burn fossil fuels and produce high levels of planet-heating pollution.

    A slow down is expected to speed up ice melt and potentially end an ocean system that has helped sustain life for thousands of years.

    “The projections we have make it look like the Antarctic overturning would collapse this century,” said Matthew England, deputy director of the Australian Research Council’s Centre for Excellence in Antarctic Science, who coordinated the study.

    “In the past, these overturning circulations changed over the course of 1,000 years or so, and we’re talking about changes within a few decades. So it is pretty dramatic,” he said.

    Most previous studies have focused on the Atlantic Meridional Overturning Circulation (AMOC), the system of currents that carry warm water from the tropics into the North Atlantic. The cold, saltier water then sinks and flows south.

    Its Southern Ocean equivalent is less studied but does an important job moving nutrient-dense water north from Antarctica, past New Zealand and into the North Pacific Ocean, the North Atlantic and Indian Ocean, the report’s authors said in a briefing.

    The circulation of deep ocean water is considered vital for the health of the sea – and plays an important role in sequestering carbon absorbed from the atmosphere.

    According to the report, while a slowdown of the AMOC would mean the deep Atlantic Ocean would get colder, the slower circulation of dense water in the Antarctic means the deepest waters of the Southern Ocean will warm up.

    “One of the concerning things of this slowdown is that there can be feedback to further ocean warming at the base of the ice shelves around Antarctica. And that would lead to more ice melt, reinforcing or amplifying the original change,” England said.

    As global temperatures rise, Antarctic ice is expected to melt faster, but that doesn’t mean the circulation of deep water will increase – in fact the opposite, scientists said.

    In a healthy system, the cold and salty – or dense – consistency of melted Antarctic ice allows it to sink to the deepest layer of the ocean. From there it sweeps north, carrying carbon and higher levels of oxygen than might otherwise be present in water around 4,000 meters deep.

    As the current moves northward, it agitates deep layers of debris on the ocean floor – remains of decomposing sea life thick with nutrients – that feed the bottom of the food chain, scientists said.

    In certain areas, mostly south of Australia in the Southern Ocean and in the tropics, this nutrient-rich cold water moves toward the surface in a process called upwelling, distributing the nutrients to higher layers of the ocean, England said.

    However, Wednesday’s study found that as global temperatures warm, melting sea ice “freshens” the water around Antarctica, diluting its saltiness and raising its temperature, meaning it’s less dense and doesn’t sink to the bottom as efficiently as it once did.

    The report’s co-author, Steve Rintoul from Australia’s Commonwealth Scientific and Industrial Research Organisation and the Australian Antarctic Program Partnership, said sea life in waters worldwide rely on nutrients brought back up to the surface, and that the Antarctic overturning is a key component of that upwelling of nutrients.

    “We know that nutrients exported from the Southern Ocean in other current systems support about three quarters of global phytoplankton production – the base of the food chain,” he said.

    “We’ve shown that the sinking of dense water near Antarctica will decline by 40% by 2050. And it’ll be sometime between 2050 and 2100 that we start to see the impacts of that on surface productivity.”

    England added: “People born today are going to be around then. So, it’s certainly stuff that will challenge societies in the future.”

    The report’s authors say the slowing of the Antarctic ocean overturning has other knock-on effects for the planet – for example, it could shift rain bands in the tropics by as much as 1,000 kilometers (621 miles).

    “Shut it down completely and you get this reduction of rainfall in one band south of the equator and an increase in the band to the north. So we could see impacts on rainfall in the tropics,” said England.

    Earlier this month, the Intergovernmental Panel on Climate Change (IPCC) warned in its latest report that the impacts of rising global temperatures were more severe than expected. Without immediate and deep changes, the world is hurtling toward increasingly dangerous and irreversible consequences of climate change, it added.

    The IPCC report found that the goal of limiting global warming to 1.5 degrees Celsius (2.7 degrees Fahrenheit) above preindustrial levels was still possible, but it’s becoming harder to achieve the longer the world fails to cut carbon pollution.

    England points out that the IPCC predictions don’t include ice melt from Antarctic ice sheets and shelves.

    “That’s a very significant component of change that’s already underway around Antarctica with more to come in the next few decades,” England said.

    Rintoul said the study was another urgent warning on top of all the ones that have come before it.

    “Even though the direct effect on fisheries through reduced nutrient supply might take decades to play out, we will commit ourselves to that future with the choices we make over the next decade.”

  • Historic treaty reached to protect marine life on high seas

    Historic treaty reached to protect marine life on high seas

    [ad_1]

    For the first time, United Nations members have agreed on a unified treaty to protect biodiversity in the high seas – representing a turning point for vast stretches of the planet where conservation has previously been hampered by a confusing patchwork of laws.

    The U.N. Convention on the Law of the Sea came into force in 1994, before marine biodiversity was a well-established concept. The treaty agreement concluded two weeks of talks in New York.

    The last international agreement on ocean protection was signed 40 years ago in 1982 – the UN Convention on the Law of the Sea, according to BBC News.   

    An updated framework to protect marine life in the regions outside national boundary waters, known as the high seas, had been in discussions for more than 20 years, but previous efforts to reach an agreement had repeatedly stalled. The unified agreement treaty, which applies to nearly half the planet’s surface, was reached late Saturday.

    “We only really have two major global commons — the atmosphere and the oceans,” said Georgetown marine biologist Rebecca Helm. While the oceans may draw less attention, “protecting this half of earth’s surface is absolutely critical to the health of our planet.”

    Nichola Clark, an oceans expert at the Pew Charitable Trusts who observed the talks in New York, called the long-awaited treaty text “a once-in-a-generation opportunity to protect the oceans — a major win for biodiversity.”  

    The treaty will create a new body to manage conservation of ocean life and establish marine protected areas in the high seas. And Clark said that’s critical to achieve the U.N. Biodiversity Conference’s recent pledge to protect 30% of the planet’s waters, as well as its land, for conservation.

    Treaty negotiations initially were anticipated to conclude Friday, but stretched through the night and deep into Saturday. Rebecca Hubbard, the director of the High Seas Alliance, called it a “two week long rollercoaster ride of negotiations and super-hero efforts in the last 48 hours.” 

    The crafting of the treaty, which at times looked in jeopardy, represents “a historic and overwhelming success for international marine protection,” said Steffi Lemke, Germany’s environment minister.

    “For the first time, we are getting a binding agreement for the high seas, which until now have hardly been protected,” Lemke said. “Comprehensive protection of endangered species and habitats is now finally possible on more than 40% of the Earth’s surface.”

    The treaty also establishes ground rules for conducting environmental impact assessments for commercial activities in the oceans.

    “It means all activities planned for the high seas need to be looked at, though not all will go through a full assessment,” said Jessica Battle, an oceans governance expert at the Worldwide Fund for Nature.

    Several marine species — including dolphins, whales, sea turtles and many fish — make long annual migrations, crossing national borders and the high seas. Efforts to protect them, along with human communities that rely on fishing or tourism related to marine life, have long proven difficult for international governing bodies.

    “This treaty will help to knit together the different regional treaties to be able to address threats and concerns across species’ ranges,” Battle said.

    That protection also helps coastal biodiversity and economies, said Gladys Martínez de Lemos, executive director of the nonprofit Interamerican Association for Environmental Defense focusing on environmental issues across Latin America.

    “Governments have taken an important step that strengthens the legal protection of two-thirds of the ocean and with it marine biodiversity and the livelihoods of coastal communities,” she said.

    The question now is how well the ambitious treaty will be implemented.

    Formal adoption also remains outstanding, with numerous conservationists and environmental groups vowing to watch closely.

    The high seas have long suffered exploitation due to commercial fishing and mining, as well as pollution from chemicals and plastics. The new agreement is about “acknowledging that the ocean is not a limitless resource, and it requires global cooperation to use the ocean sustainably,” Rutgers University biologist Malin Pinsky said.

  • One of the biggest autonomous transportation tests is operating deep underwater

    One of the biggest autonomous transportation tests is operating deep underwater

    [ad_1]

    Boeing’s lineup of unmanned, undersea vehicles (UUV) can operate autonomously for months at a time on a hybrid rechargeable propulsion power system. Pictured above is the 18-foot Echo Ranger. The aerospace and defense contractor also makes the 32-foot Echo Seeker, and its latest innovation, and the largest autonomous sub, is the Voyager at 51-feet.

    Boeing

    More than 80% of the ocean remains unexplored by humans but could soon be mapped by autonomous underwater robots. But is that all unmanned submarines will be used for?

    Autonomous robot submarines — also referred to as autonomous underwater vehicles, or AUVs — are able to explore high-pressure areas of the ocean floor that are unreachable by humans through preprogrammed missions, allowing them to function without humans aboard, or controlling them. They’re often used by scientists for underwater research as well as oil and gas companies for deep water surveys, but as defensive security threats continue to grow, the largest sector in the AUV market has become the military.

    AUVs can be helpful tools in military ocean exploration, obtaining critical information such as mapping the seafloor, looking for mines — a current use case in the Russia-Ukraine war — and supplying underwater surveillance. Navies worldwide are investing in unmanned underwater vehicles to elevate their fleet of below-water defense tools. 

    Defense company Anduril Industries kickstarted its expansion from land to sea when it acquired AUV manufacturer Dive Technologies in February. The acquisition gave them a customizable AUV of their own called the Dive-LD.

    “There are more and more threats that are on top of the water and under the water that can really only be addressed by robotic systems that can hide from enemy surveillance, that can hide from what you can see in the air and can do things that are only possible to do underwater,” Palmer Luckey, Anduril Industries co-founder, told CNBC’s “Squawk on the Street” at the time of the acquisition. 

    In addition to the Dive Technologies acquisition, Anduril Industries expanded to Australia in March, then in May partnered with the Australian Defense Force to work on a $100 million project to design and create three extra large AUVs for the Royal Australian Navy.

    In the U.K., the Royal Navy recently ordered its first AUV named Cetus XLUUV from MSubs, which is expected to be completed in about two years. The U.K.’s Ministry of Defence also announced in August the donation of six autonomous underwater drones to Ukraine to aid in their fight against Russia by locating and identifying Russian mines. 

    China recently completed construction on the Zhu Hai Yun, an unmanned ship made to launch drones and that utilizes artificial intelligence to navigate the seas with no crew required. The ship is described by officials in Beijing as a research tool, but many experts expect it to also be used for military purposes.

    Boeing has been working on AUVs since the 1970s and has collaborated with the United States Navy and DARPA on a number of underwater vehicle projects in recent years. The Echo Voyager, Boeing’s first extra-large unmanned undersea vehicle, first began operating in 2017 after about five years of design and development. It’s 51-feet long with a 34-foot payload that is approximately the size of a school bus and can be used for oil and gas exploration, long-duration surveying and analyzing infrastructure for oil and gas companies.

    The AUV has spent almost 10,000 hours operating at sea and has transited hundreds of nautical miles autonomously. It’s versatile and modular, Ann Stevens, the senior director of Maritime Undersea at Boeing, said in an interview.

    “There is no other vehicle of that size and capability in the world, Echo Voyager is the only one,” Stevens said.

    Boeing has been in the process of developing the Orca XLUUV with funding from the United States Navy. The company won a $43 million contract to build four of the AUVs, which are based off of the design of Boeing’s Echo Voyager, in February 2019. The project has experienced some production delays – the Orca XLUUVs that were originally scheduled to be delivered in December 2020 are now planned to be finished in 2024. The company cited cost concerns as well as supply chain issues due to the pandemic as reasons for the change.

    “It’s a development program, and we’re developing groundbreaking technology that’s never been built before,” Stevens said. “We’ve been in lock step with the Navy the whole way. We’re going to have a great vehicle that comes out the other end.”

    Robotics and automation in general is a young field, according to Maani Ghaffari, an assistant professor in the Naval Architecture and Marine Engineering department at the University of Michigan. Researchers began developing AUVs around 50-60 years ago, though the quality and variety of sensors that were necessary to build the systems were limited. Today, sensors are smaller, cheaper and higher quality.

    “We are at the stage where we can build much better and more efficient hardware and sensors for the robots to the extent that we’re hoping to deploy some of them in everyday life at some point,” Ghaffari said.

    AUVs still have some challenges to overcome before they’re a feasible mechanism for everyday use, for one, the robots have to function in an arguably harsher environment than air, where the water’s higher density creates hydraulic drag that slows down the robot and drains its battery faster. 

    However, some AUVs in development have impressive speeds and endurance. When it is completed, Boeing said it expects the Orca XLUUV to sail 6,500 nautical miles without being connected to another ship. Anduril reports that the Dive-LD can be sent on missions autonomously for up to 10 days and is made to last for weeks-long missions.

    Environmental challenges are the main problem spots for AUVs. Underwater communication from the unmanned submarines is limited as signals used to transfer messages in air get absorbed quickly in water, and cameras on the vehicles are not as clear underwater. 

    Whether AUVs will eventually be used as more than a surveillance tool and engage in underwater warfare is more of a question of ethics within artificial intelligence and robotics, Ghaffari said. While the vehicles may be sophisticated enough to make autonomous decisions, concerns arise when the decisions may impact human lives.

    “The one idea is that you basically pass the battle to these robots instead of soldiers – less people might die, but on the other hand, when the artificial intelligence can make decisions faster than humans and act faster than humans, that might increase the amount of damage that they can cause,” Ghaffari said. “That’s the frontier that hasn’t been explored, and we have to talk about it as we make progress in the future.”

  • Flotsam found off New York may be from famous SS Savannah

    Flotsam found off New York may be from famous SS Savannah

    [ad_1]

    NEW YORK — A chunk of weather-beaten flotsam that washed up on a New York shoreline after Tropical Storm Ian last fall has piqued the interest of experts who say it is likely part of the SS Savannah, which ran aground and broke apart in 1821, two years after it became the first vessel to cross the Atlantic Ocean partly under steam power.

    The roughly 13-foot (4-meter) square piece of wreckage was spotted in October off Fire Island, a barrier island that hugs Long Island’s southern shore, and is now in the custody of the Fire Island Lighthouse Preservation Society. It will work with National Park Service officials to identify the wreckage and put it on public display.

    “It was pretty thrilling to find it,” said Betsy DeMaria, a museum technician at the park service’s Fire Island National Seashore. “We definitely are going to have some subject matter experts take a look at it and help us get a better view of what we have here.”

    It may be difficult to identify the wreckage with 100% certainty, but park service officials said the Savannah is a top contender among Fire Island’s known shipwrecks.

    Explorers have searched for the Savannah for over two centuries but have not found anything they could definitively link to the famous ship. The newly discovered wreckage, though, “very well could be” a piece of the historic shipwreck, said Ira Breskin, a senior lecturer at the State University of New York Maritime College in the Bronx. “It makes perfect sense.”

    Evidence includes the 1-to-1.3-inch (2.5-to-3.3-centimeter) wooden pegs holding the wreckage’s planks together, consistent with a 100-foot (30.5-meter) vessel, park service officials said in a news release. The Savannah was 98 feet, 6 inches (30 meters) long. Additionally, the officials said, the wreckage’s iron spikes suggest a ship built around 1820. The Savannah was built in 1818.

    Breskin, author of “The Business of Shipping,” noted that the Savannah’s use of steam power was so advanced for its time that the May 24, 1819, start of its transatlantic voyage is commemorated as National Maritime Day. “It’s important because they were trying to basically show the viability of a steam engine to make it across the pond,” he said.

    Breskin said a nautical archaeologist should be able to help identify the Fire Island wreckage, which appears likely to be from the Savannah. “It’s plausible, and it’s important, and it’s living history if the scientists confirm that it is what we think it is,” he said.

    The Savannah, a sailing ship outfitted with a 90-horsepower steam engine, traveled mainly under sail across the Atlantic, using steam power for 80 hours of the nearly month-long passage to Liverpool, England.

    Crowds cheered as the Savannah sailed from Liverpool to Sweden and Russia and then back to its home port of Savannah, Georgia, but the ship was not a financial success, in part because people were afraid to travel on the hybrid vessel. The Savannah’s steam engine was removed and sold after the ship’s owners suffered losses in the Great Savannah Fire of 1820.

    The Savannah was transporting cargo between Savannah and New York when it ran aground off Fire Island. It later broke apart. The crew made it safely to shore and the cargo of cotton was salvaged, but the Augusta Chronicle & Georgia Gazette reported that “Captain Holdridge was considerably hurt by being upset in the boat.”

    Explorers have searched for the Savannah over the two centuries since it but have not found anything they could definitively link to the famous ship. The newly discovered wreckage, though, “very well could be” a piece of the historic shipwreck, Breskin said. “It makes perfect sense.”
