  • “Rare, uncut” video of the 1986 dive exploring the Titanic wreckage to be released

    “Rare, uncut” video of the 1986 dive exploring the Titanic wreckage to be released

    [ad_1]

    An oceanographic institution is releasing over an hour of “mostly unreleased” footage from the 1986 dive exploring the wreck of the R.M.S. Titanic. 

    The footage is being shared by the Woods Hole Oceanic Institution in honor of the 25th anniversary of James Cameron’s Academy Award-winning movie, “Titanic,” which has been re-released in theaters around the country. 

    The wreckage of the Titanic was first found by researchers from the WHOI, working in partnership with a French institute, in 1985. That expedition was led by Dr. Robert Ballard, the WHOI said in a statement. In June 1986, the team returned to the wreck site with the human-occupied submersible Alvin, and a remotely operated vehicle (ROV) called Jason Junior. That mission marked the “first time humans set eyes on the ill-fated ship” since its sinking in 1912, according to the institution.

    The “rare, uncut and mostly unnarrated footage” is expected to be uploaded to the WHOI’s YouTube channel later on Wednesday. Currently, a one-minute preview video is available on the institution’s channel. The brief narration that does exist is done by Ballard, the WHOI said. 

    According to the WHOI, video highlights from the footage will include images of the Alvin submersible approaching the ship and parking on its deck, interior shots of the wreck including a look inside a chief officer’s cabin and footage of debris on the ocean floor.

    “More than a century after the loss of Titanic, the human stories embodied in the great ship continue to resonate,” said Cameron, in a statement provided by the WHOI. “Like many, I was transfixed when Alvin and Jason Jr. ventured down to and inside the wreck. By releasing this footage, WHOI is helping tell an important part of a story that spans generations and circles the globe.”

    About 2,200 people were aboard the ocean liner, heralded as “unsinkable” and designed to be the most luxurious ship available, when it set out into the North Atlantic. About 1,500 people died after the ship struck an iceberg and sank in the early hours of Apr. 15, 1912 with only 700 passengers and crew members surviving to be rescued by the R.M.S. Carpathia. The wreckage of the ship has remained about 12,600 feet below the ocean’s surface ever since.

     According to the WHOI, efforts to “locate and salvage” the ship began almost immediately after the sinking, but technical limitations kept the wreck hidden for nearly 75 years. By 1985, new imaging technology captured photographs of the ship and helped researchers find the wreck. 

    Dana Yoerger, a WHOI engineer and a member of both the 1985 and 1986 missions, said the 1986 expedition “changed how we explore the deep ocean.” 

    “The human-occupied submersible Alvin brought scientists down 12,500 feet to the Titanic,” Yoerger said in a statement. “Operating from Alvin, we used the Jason Jr robot to penetrate Titanic and transmit images of the ship’s interior while the people remained safely outside the wreckage.  For WHOI and the entire ocean research community, these advances provided an important foundation for modern deep-sea exploration technology.”

  • Is offshore wind development a threat to whales? Here’s what to know.

    Is offshore wind development a threat to whales? Here’s what to know.

    [ad_1]

    In less than two months, seven dead whales have washed up on the shores of New Jersey and New York. What’s behind the mortalities has not been clearly established, but theories abound. Some have pointed blame at offshore wind development in the region and claimed construction of the sites causes harm to marine animals. But federal officials are pushing back, saying that’s not what the evidence shows.

    Here’s what we know about the recent whale deaths and what researchers say could be the cause. 

    What happened to the whales? 

    Several dead whales have washed up on New Jersey and New York beaches since the beginning of December. Two were found in New York, with a 31-foot-long humpback whale washing up in Amagansett, on Long Island, on Dec. 6, and a 30-foot-long sperm whale found on Rockaway Beach on Dec. 12. The others have been found in New Jersey, including a 12-foot infant sperm whale in Keansburg on Dec. 5, a 30-foot humpback on Strathmere beach on Dec. 10, a humpback whale in Atlantic City on Dec. 23, and another 30-foot humpback whale in Atlantic City on Jan. 7. 

    The most recent was on Jan. 12, when a 32-foot-long humpback whale washed up in Brigantine, New Jersey.

    The causes of death for these whales have not officially been confirmed, as it can take several months to obtain results of test sampling. But some of the cases did reveal information about what may have contributed. 

    The most recent whale, for example, may have been killed from a vessel strike after responders observed evidence of blunt trauma to the whale’s head and thoracic area, according to the Marine Mammal Stranding Center. Likewise, the whale found on Dec. 7 was also found with “marks from a suspected ship strike” near its blowhole and on the whale’s right side. In that case, responders also found a large hematoma — a pool of blood — under one of the suspected strike marks, and also found scars from a possible entanglement. 

    Why are some blaming wind energy? 

    Even though pathology results have not yet been released, some local groups have accused offshore wind energy development in the region of being responsible for the deaths. 

    The increase in offshore wind energy development comes amid the White House’s goal to ramp up offshore energy capacity to 30 gigawatts by 2030 — an amount the administration says could provide power to more than 10 million Americans’ homes for a year. 

    On Jan. 9, a local group called Clean Ocean Action issued a press release demanding “an immediate and fully transparent investigation” into the whale deaths, a “hard stop” on existing offshore wind energy development activities, and a pause to any “new, planned, or pending” development permitting activities. 

    “These tragic multiple deaths of mostly young, endangered whales are of no apparent cause, however, the only new activity in the ocean is the unprecedented concurrent industrial activity by over 11 companies in the region’s ocean, which allows the harassment and harm of tens of thousands of marine mammals,” Cindy Zipf, executive director of the organization, said in the release.

    Clean Ocean Action accuses the National Oceanic and Atmospheric Administration of giving “the green light” for offshore wind companies to “harm, harass, injure and kill” marine mammals in their development process through Incidental Take Authorizations. The ITAs issued by NOAA may allow the unintentional harassment, injury or killing of marine mammals in connection to authorized activities, “including construction projects, scientific research projects, oil and gas development, and military exercises.”

    But during a call with reporters on Wednesday, NOAA officials reiterated that the agency “has not authorized — or proposed to authorize — mortality or serious injury of whales for any wind-related action.” It also said “no whale mortality has been attributed to offshore wind activity.” 

    According to NOAA, there are 12 active authorizations for “Level B” harassment from offshore wind sites in the Atlantic Ocean from New England to the Carolinas, meaning that companies will likely disturb animals, but do not have permission to injure or kill. There are also two active authorizations that allow non-serious injury, specifically auditory injury, from “exposure to noise from pile driving.” 

    Benjamin Laws, NOAA Fisheries deputy chief for the permits and conservation division, told reporters that “no injury, and certainly no mortality,” has been authorized. 

    Laws said that most of the offshore activity right now is surveys for more developments. During a vessel-based survey, a piece of equipment that emits sound is paired with a receiver and towed through the water in a zig-zag fashion to track how sound waves bounce off the sea floor. 

    Laws said that the agency did not have “evidence that would support the connection between the survey work and these recent stranding events or any stranding events in the last several years.” 

    Erica Staaterman, a bioacoustician with the Bureau of Ocean Energy Management, said during the call that the equipment used in these surveys is not as intrusive to marine animals compared to the equipment used in oil and gas construction. Whereas offshore oil and gas development uses seismic air guns, the equipment being used for offshore wind development surveys emits a smaller amount of acoustic energy in a smaller radius and are used for shorter periods of time, she explained. 

    The agency added that when surveys are done, vessels are required to slow their speed and must be joined by protected species observers at all times, with at least one observer during the day and at least two during the night with night vision devices. 

    NOAA has acknowledged that any activity that puts noise in the ocean could potentially impact marine mammals, namely with their navigation, habitats and vessel traffic. However, there is no evidence that’s what happened in the most recent cases of whale strandings, the agency said. 

    If development isn’t responsible for recent whale deaths, what is?

    One of the most important aspects of the string of whale deaths to note is that humpback whales, which have made up a majority of the recent events, have been undergoing an unusual mortality event since 2016. Since then, there have been roughly 178 deaths, most of which occurred in Massachusetts and New York. Necropsies have been done on at least half of those whales, of which about 40% had evidence of either a ship strike or entanglement. More research on the cause for the event as a whole is needed. 

    Both humpback and sperm whales, the two species seen washing up on shores, are listed as endangered, according to NOAA. Human interaction remains the species’ No. 1 threat, namely from vessel strikes, entanglements, noise pollution and marine debris. 

    Sarah Wilkin, coordinator of the Marine Mammal Health and Stranding Response Program, said Wednesday that humpback whale strandings in particular tend to happen in the mid-Atlantic during winter. Researchers are still working on determining if the recent strandings is an elevated number compared to previous years, she said.

    Climate change is also anticipated to have a major impact on the whales, as changes in the ocean can impact their habitat and food availability. Sperm whales are expected to be more resilient to these changes, as they have a more widespread presence worldwide. 

    However, these are reasons for overall deaths and are not specific to the most recent string of events. The reasons for each of the most recent deaths are still being determined.

  • Microscopic dust from desert storms has been hiding the true extent of global warming, study finds

    Microscopic dust from desert storms has been hiding the true extent of global warming, study finds

    [ad_1]

    Desert storms that have sent massive plumes of dust across the oceans may have a small but significant effect on global temperatures, scientists say. New research found the microscopic particles circulating through the atmosphere had a “slight overall cooling effect on the planet” that masked just how much the planet has truly warmed over recent decades. 

    The UCLA research, published in Nature Reviews Earth & Environment on Tuesday, found that the amount of atmospheric dust has increased by about 55% since pre-industrial times, with many ups and downs along the way. According to lead study author Jasper Kok, that increase is likely due to changes in global climate, such as wind speeds in some deserts, as well as land-use changes, such as transforming land into agriculture and diverting water for irrigation.

    But the researchers say the impact of that dust has not been adequately factored into studies of global temperature trends. The overall increase in dust, according to Kok, “could have masked up to 8% of the greenhouse warming” that’s taken place since the Industrial Revolution. 

    “By adding the increase in desert dust, which accounts for over half of the atmosphere’s mass of particulate matter, we can increase the accuracy of climate model predictions,” he said in a press release. “This is of tremendous importance because better predictions can inform better decisions of how to mitigate or adapt to climate change.”

    The increase in atmospheric dust largely stems from Asia and North Africa, the study says. It’s estimated that 100 million tons of dust are picked up from Africa’s Sahara Desert, according to NASA’s Earth Observatory, which said that the Sahara is “by far” the largest source of atmospheric dust on the planet. The particles from these plumes serve a complex role. While they are known to trigger respiratory issues, degrade air quality and obscure visibility, they also absorb and reflect light from the sun and are filled with minerals that help feed plants and phytoplankton, according to NASA. 

    And when it comes to its impact on the climate specifically, the researchers found that dust particles only increase the complexity. In some ways, the dust contributes to warming, such as when it darkens snow and ice surfaces. But in others, it counteracts that warming, like when the dust helps reflect sunlight from the Earth and helps the ocean absorb more carbon dioxide, a greenhouse gas that largely contributes to planetary warming. 

    Stuart Evans, an assistant professor at the University of Buffalo who studies atmospheric dust, told CBS News that the study, which he was not involved in, helps provide a “benchmark” for how much change we have seen regarding atmospheric dust and climate change.

    “It provides a starting point for further studies of the human impacts on this piece of the climate system,” he said.

     e, Dust indirect effects on cirrus clouds, separated by the dominant ice crystal formation mechanism in the absence of dust, occurring through dust changing the number and size of ice crystals. f, Dust semi-direct effect (SDE) on low clouds, separated by location of dust relative to clouds, owing to local heating generated by dust absorption. g, Radiative effects of dust deposited on snow and ice through changes in reflectivity and absorption. h, Effect of dust on CO2 drawdown via interactions with ocean biogeochemistry. Dust affects climate through a wide range of mechanisms that alternately cool and warm the climate, making the magnitude and sign of the net radiative effect of dust on climate uncertain. 

    Nature Reviews Earth & Environment


    Overall, the study says “it is more likely that dust cools the climate than warms.” But that information, according to Kok, is lacking from current climate models. His team looked at a dozen climate models, and he told CBS News that “not a single” one came close to capturing the increase they found. 

    “We show desert dust has increased, and most likely slightly counteracted greenhouse warming, which is missing from current climate models,” he said. “The increased dust hasn’t caused a whole lot of cooling — the climate models are still close — but our findings imply that greenhouses gases alone could cause even more climate warming than models currently predict.”

    Evans said he’s seen dust in most models, but that it’s “typically not well-represented.” 

    “Most models don’t capture the long-term trend at all,” he said. “…If you want to use a climate model to predict the future, you’d want to know that it has correctly represented the past. And when it comes to dust, models aren’t there yet.” 

    That doesn’t mean current models are wrong, both researchers said — just that there’s now more information that can improve on our understanding. Evans said it could also help researchers understand more about climate sensitivity, or how sensitive Earth is to a variety of factors in the climate. 

    If the rise in atmospheric dust eventually slows down or begins to decline, “the previously hidden additional warming potential from greenhouse gases could cause somewhat more rapid climate warming than models predict,” a press release from the University of California says. 

    But right now, it’s unclear how the dust levels will change in the future. Kok explained that dust storms are “very complicated” and depend on a variety of factors, including wind speed, precipitation, evaporation and land-use.

    “Although some areas, like the southwestern part of the United States, are predicted to get drier, possibly increasing dust there in the future, other areas like the Sahara desert might actually get wetter, possibly decreasing dust there,” he told CBS News. “So what the future brings in terms of total dustiness is not known and models disagree on this, with some predicting more dust and others less dust.”

    Evans offered a similar assessment, saying “the future of dust is uncertain.”

    “The models can’t agree … and none of them have really distinguished themselves as being the single superior model that you should trust over others,” he said. “…Predicting dust is hard because simulating dust is a very difficult challenge that is still being actively worked on.” 

    But what we do know is that the planet has already warmed by about 2.2 degrees Fahrenheit (1.2 degrees Celsius) since the mid-1800s, with the past eight years, from 2013 to 2022, the hottest in recorded history. And Kok says if the dust had not increased, global temperatures would likely be another 0.1 degrees Fahrenheit higher. 

    As scientists have repeatedly stressed, every fraction of a degree matters when it comes to climate change. 

    “This is valuable in helping us improve our precision with our predictions because it is doing an accounting of a frequently overlooked aspect of the climate system,” Evans said. “I think in terms of action, the only thing anybody needs to know is that greenhouse gases are making the world hotter and the only solution is to reduce their concentration in the atmosphere.”

  • Ocean heat shatters record with warming equal to 5 atomic bombs exploding “every second of every day” for a year. Researchers say it’s “getting worse.”

    Ocean heat shatters record with warming equal to 5 atomic bombs exploding “every second of every day” for a year. Researchers say it’s “getting worse.”

    [ad_1]

    During World War II, the U.S. dropped an atomic bomb over Hiroshima, Japan, wiping out 90% of the city. Last year, researchers say, the ocean heated up an amount equal to the energy of five of those bombs detonating underwater “every second for 24 hours a day for the entire year.” 

    John Abraham, a professor at the University of St. Thomas, is among more than a dozen scientists who revealed this week the ocean in 2022 was “the hottest ever recorded by humans.” It increased by 10.9 Zetta Joules, an amount of energy equivalent to the atomic bomb dropped on Hiroshima and an amount of heat about 100 times more than the electricity generated worldwide in 2021. 

    Four basins of the seven world ocean regions – the North Pacific, North Atlantic, Mediterranean and southern oceans – had the highest heat records since the 1950s. 

    This marks the fourth time in a row that ocean heat content has surpassed records broken the year prior. And while it may seem like a “broken record” at this point, Abraham said this is anything but “normal.”

    “This is a continuing, ongoing trend,” he said. “It’s getting worse every year.” 

    Here’s what the findings, published in the Advances in Atmospheric Sciences, mean for the current state of the planet, and the future. 

    More fuel for extreme weather

    Ken Caldeira, a climate scientist at the Carnegie Institution for Science as well as a senior scientist at Breakthrough Energy, told CBS News that the ocean “is the pacemaker of the climate systems response to our CO2 emissions.” 

    “The amount of greenhouse gases in the atmosphere is increasing year by year. And these greenhouse gases, trap energy in Earth’s system prevent it from going to space, and most of that energy goes into the ocean, which causes the ocean to warm,” he said. 

    From there, some of the ocean heat is transferred back to the atmosphere, Abraham said, as is moisture and humidity, creating a surge of more energy that “makes storms more powerful.” 

    “So when oceans warm and when the Earth warms, it makes our weather wilder,” Abraham said. “We go from one extreme to the other, more rapidly.” 

    The most recent example of this can be seen in California, which has undergone weeks of heavy flooding and record-breaking rain as a series of atmospheric rivers barrage the West Coast. Climate change didn’t cause those atmospheric rivers and storms, but a warmer atmosphere has been linked to making storms more intense.

    Oceans are facing another problem. When it rains, the fresh water from the clouds helps decrease salinity in the ocean as new water comes down. But data shows that rain isn’t providing equal coverage across the seas, with areas that typically get a lot of rain experiencing even more in the past year, reducing their salinity. Meanwhile those in usually dry environments become even drier, increasing those levels as more water evaporates than comes down.

    Because of this, the salinity-contrast index – essentially the difference between the highest and lowest salinity levels in the upper 2,000 meters of the ocean – also reached its highest level on record last year. 

    A high salinity-contrast index and high ocean temperatures can individually make weather events more severe. 

    “And they are now conspiring together,” Abraham told CBS News. “Their effects are additive.” 

    Ocean regulation has become “problematic” 

    The increasing measures of temperature and salinity have also led to another issue within the ocean – it’s ability to self-regulate. Water usually experiences vertical mixing, in which water from the top carries valuable gases and heat to the bottom of the ocean while water from the bottom moves up, carrying with it vital nutrients. 

    The latest study explains that this process is “a central element of Earth’s climate system.” But since 1960, researchers estimate that stratifcation, or the separation of water layers that makes this process more difficult, has increased by 5.3% in the upper 2,000 meters of the ocean and up to about four times that amount in the upper 150 meters. 

    “What we’ve discovered is mixing is happening less,” Abraham said. “…Because of climate change and because we’ve heated the surface waters so much, they aren’t able to fall downwards … And that is problematic.” 

    That’s because if heat from the surface can’t mix with the cooler water below, that surface will only get warmer and reduce how much carbon the water can store – an ability that is vital to extending the global warming process. The ocean is like a sponge for carbon emissions, taking in about 90% of the heat from the worldwide total, but if its ability to do so is diminishing as emissions are only increasing, experts say the planet will only warm faster, making the worst impacts of climate change happen sooner. 

    Investing in climate solutions a “no brainer” 

    All of this data gathered leads Abraham to believe that “we will never hit the Paris Accord goals” of keeping global warming within 1.5 degrees Celsius compared to pre-industrial levels. Even the United Nations has said that the world is more on track to hit nearly 3 degrees Celsius by the time today’s children are grandparents. 

    We can’t undo the damage that has already been done, Caldeira said, but we can prevent it from getting worse. 

    “Right now, our carbon dioxide emissions from our energy system are around 100 times bigger than all of the carbon dioxide emissions from every volcano and mid-ocean ridge and geothermal vents and everything that exists in nature,” he said. “…The most important thing we can do is transition to an energy system that doesn’t use the atmosphere and the oceans as a waste dump.”

    “We can solve this problem today with today’s technology, we just need to get off your asses and start doing it,” Abraham added, saying that doing so “is a no brainer” when you consider the the exorbitant costs of climate disasters, which topped $165 billion in the U.S. alone last year. 

    The cost of green energy, for example, has substantially decreased in recent years, and in many cases, is now comparable or even cheaper to coal. Over the past decade, the cost to install solar panels has dropped more than 60%. And last year’s passage of the Inflation Reduction Act also created numerous opportunities for discounted home upgrades, electric vehicles and more.  

    “We’ve reached an economic tipping point where it’s starting to make economic sense to use clean energy,” Abraham said. “…Earth’s climate is a heavy locomotive. And if you want to stop a heavy locomotive, you’ve got to put the brakes on and it’ll take you like a mile to stop. … You’ve got to start taking actions early and give it time give time for those actions to have measurable outcomes.”

  • Satellite launched to map the world’s oceans, lakes, rivers

    Satellite launched to map the world’s oceans, lakes, rivers

    [ad_1]

    A U.S.-French satellite that will map almost all of the world’s oceans, lakes and rivers rocketed into orbit Friday.

    The predawn launch aboard a SpaceX rocket from Vandenberg Space Force Base in California capped a highly successful year for NASA.

    Nicknamed SWOT — short for Surface Water and Ocean Topography — the satellite is needed more than ever as climate change worsens droughts, flooding and coastal erosion, according to scientists. Cheers erupted at control centers in California and France as the spacecraft started its mission.

    “It is a pivotal moment, and I’m very excited about it,” said NASA program scientist Nadya Vinogradova-Shiffer. “We’re going to see Earth’s water like we’ve never before.”

    About the size of a SUV, the satellite will measure the height of water on more than 90% of Earth’s surface, allowing scientists to track the flow and identify potential high-risk areas. It will also survey millions of lakes as well as 1.3 million miles (2.1 million kilometers) of rivers.

    The satellite will shoot radar pulses at Earth, with the signals bouncing back to be received by a pair of antennas, one on each end of a 33-foot (10-meter) boom.

    It should be able to make out currents and eddies less than 13 miles (21 kilometers) across, as well as areas of the ocean where water of varying temperatures merge.

    NASA’s current fleet of nearly 30 Earth-observing satellites cannot make out such slight features. And while these older satellites can map the extent of lakes and rivers, their measurements are not as detailed, said the University of North Carolina’s Tamlin Pavelsky, who is part of the mission.

    Perhaps most importantly, the satellite will reveal the location and speed of rising sea levels and the shift of coastlines, key to saving lives and property. It will cover the globe between the Arctic and Antarctica at least once every three weeks, as it orbits more than 550 miles (890 kilometers) high. The mission is expected to last three years.

    Laurie Leshin, the director of NASA’s Jet Propulsion Laboratory in Pasadena, California, noted that while the agency is known for its Mars rovers and space telescopes, “this is the planet we care most about.”

    “We’ve got a lot of eyes on Earth,” with even more globe-surveying missions planned in the next few years, she added.

    NASA and the French Space Agency collaborated on the $1.2 billion SWOT project — some 20 years in the making — with Britain and Canada chipping in.

    Already recycled, the first-stage booster returned to Vandenberg eight minutes after liftoff to fly again one day. When the double sonic booms sounded, “Everybody jumped out of their skin, and it was exhilarating. What a morning,” said Taryn Tomlinson, an Earth science director at the Canadian Space Agency.

    It’s the latest milestone this year for NASA. Among the other highlights: glamour shots of the universe from the new Webb Space Telescope; the Dart spacecraft’s dead-on slam into an asteroid in the first planetary defense test; and the Orion capsule’s recent return from the moon following a test flight.

  • New Horizons’ Alan Stern Talks About How His Titanic Trip Compares To Space Travel

    New Horizons’ Alan Stern Talks About How His Titanic Trip Compares To Space Travel

    [ad_1]

    Planetary scientist Alan Stern said he wasn’t prepared for the “intersections” his oceanic expedition to the Titanic made with his career, which includes his time leading NASA’s New Horizons mission to Pluto and the Kuiper Belt.

    Stern, who spoke to HuffPost last week, revealed the parallels he discovered between the oceanic journey he made through OceanGate Expeditions ― a company that offers trips to the Titanic’s resting place in the Atlantic Ocean ― and exploration of space.

    The scientist joined OceanGate Expeditions, which is offering $250,000 expeditions for people to see the famed ship roughly 12,500 feet below the ocean surface, on its “Titan” submersible as a mission specialist and scientific expert (such experts don’t pay fares to join the expeditions).

    A number of Stern’s contributions to the mission ― in addition to offering his planetary knowledge ― included collecting water column samples, aiding with ocean bottom sampling and providing assistance with communication to a team on the surface during the descent.

    “It has some parallels both to current and to far-future space exploration, like the exploration of ocean worlds in the outer solar system,” Stern told HuffPost. “And it didn’t all gel for me until I really made the journey and was on our way steaming back north to Canada to come back to dock.”

    Noting that fewer people have been to the Titanic’s resting place than to space, Stern reflected in journal entries he wrote in July about the ship’s tragic end and how stories about its remains are “lost in time.”

    Stern, who is set to join Virgin Galactic’s suborbital research trip next year, told HuffPost that submersibles have many of the same systems as spacecraft ― including an environmental life-support system, a communication system and a power system ― but that there are “vast” technological differences, as well.

    One example, he noted, was the inability to use radio aboard the submersible.

    “So you communicate with an acoustic modem, something like out of the ’80s… and it’s really just text messaging back and forth, and there’s a long time delay. … And if I send a message to the surface, it takes 30 seconds to get up there.”

    A look at the Titanic’s portside anchor. Stern told HuffPost that submersibles have many of the same systems as spacecraft but there are also “vast” technological differences.

    Stern recalled helping OceanGate’s chief submersible pilot Stockton Rush, the founder and CEO of the company, during the final descent and compared him to astronaut Neil Armstrong “doing the landing” as he ― in the “Buzz Aldrin” role ― called off readings from the range-finding sonar.

    Rush founded OceanGate in 2009, and the company has since embarked on expeditions to San Francisco’s Greater Farallones National Marine Sanctuary, the wreck of the Andrea Doria and the Titanic, with the company kicking off its expeditions to the Titanic in 2021.

    The expeditions to the Titanic, a luxury liner that sank in 1921, causing the loss of more than 1,500 lives, are part of a longitudinal study that has several goals, the company said, such as determining how long people will be able to recognize the Titanic, mapping the ocean floor around the ship, researching the ship as an artificial reef and providing maritime archaeologists with images and footage from dives.

    He noted that Rush asked to tell him when they could see the bottom of the ocean during their descent this summer, however, there were challenges on their journey to the Titanic, such as a reliance on sonar and spotlights to find the wreckage.

    “We know exactly where the Titanic is because of GPS and buoys. We know where it is precisely, and we know where the submersible is on the ship at the surface because of GPS,” Stern said. “But in between there are currents. And as you’re descending, you’re at the mercy of the currents.”

    Stern added that currents can vary with your depth, so while best estimates are made on how far the submersible will drift in its descent, he said, you can typically end up hundreds of meters from where you intended to be.

    Once his team reached the bottom of the ocean, they waited for clouds of sediment to settle, turned on sonar to spot the ship and drove to the Titanic. But they didn’t see it until they “were literally 20 meters from it,” he said.

    “So that’s very interesting because in spaceflight, we’re able to navigate to these incredible precisions, even after traveling across the solar system to Pluto, for example,” Stern said.

    “And it’s just different technologies, and in many ways harder, but also limited by budgets, you know. So I found it fascinating, and lots of parallels.”

    A look at the bow of the Titanic. Stern noted that “very little" of the ocean is explored in the way that people have explored Earth’s land surface.
    A look at the bow of the Titanic. Stern noted that “very little” of the ocean is explored in the way that people have explored Earth’s land surface.

    In a press release, Stern said that private-sector entities like OceanGate Expeditions mark the early days of an “unparalleled era” of deep ocean exploration.

    He told HuffPost that “very little” of the enormous area of the Earth’s oceans has been explored in the way that people have explored Earth’s land surfaces.

    “When I was a kid, no one knew where the Titanic was. They know that was still in the future for Bob Ballard to find,” Stern said, referring to the 1985 discovery.

    “And then when he went down there, the thought that people could go there relatively routinely wasn’t even a thing that you would think about. It was such a feat. And still today it’s very rare.

    “Of course, spaceflight is exploding in terms of human access, and so is the oceangoing stuff. And I saw great parallels in that. And I think that there [are] going to be some very interesting parallels in terms of the economic development of the oceans for the good of the world.”

  • Could trawler cams help save world’s dwindling fish stocks?

    Could trawler cams help save world’s dwindling fish stocks?

    [ad_1]

    PORTLAND, Maine — For years, Mark Hager’s job as an observer aboard New England fishing boats made him a marked man, seen as a meddling cop on the ocean, counting and scrutinizing every cod, haddock and flounder to enforce rules and help set crucial quotas.

    On one particularly perilous voyage, he spent 12 days at sea and no crew member uttered even a single word to him.

    Now Hager is working to replace such federally-mandated observers with high-definition cameras affixed to fishing boat masts. From the safety of his office, Hager uses a laptop to watch hours of footage of crew members hauling the day’s catch aboard and measuring it with long sticks marked with thick black lines. And he’s able to zoom in on every fish to verify its size and species, noting whether it is kept or flung overboard in accordance with the law.

    “Once you’ve seen hundreds of thousands of pounds of these species it becomes second nature,” said Hager as he toggled from one fish to another.

    Hager’s Maine-based start-up, New England Maritime Monitoring, is one of a bevy of companies seeking to help commercial vessels comply with new U.S. mandates aimed at protecting dwindling fish stocks. It’s a brisk business as demand for sustainably caught seafood and around-the-clock monitoring has exploded from the Gulf of Alaska to the Straits of Florida.

    But taking the technology overseas, where the vast majority of seafood consumed in the U.S. is caught, is a steep challenge. Only a few countries can match the U.S.′ strict regulatory oversight. And China — the world’s biggest seafood supplier with an ignominious record of illegal fishing — appears unlikely to embrace the fishing equivalent of a police bodycam.

    The result, scientists fear, could be that well-intended initiatives to replenish fish stocks and reduce unintentional bycatch of threatened species like sharks and sea turtles could backfire: By adding to the regulatory burdens already faced by America’s skippers, more fishing could be transferred overseas and further out of view of conservationists and consumers.

    “The challenge now is getting the political will,” said Jamie Gibbon, an environmental scientist at The Pew Charitable Trusts who is leading its efforts to promote electronic monitoring internationally. “We are getting close to the point where the technology is reliable enough that countries are going to have to show whether they are committed or not to transparency and responsible fisheries management.”

    To many advocates, electronic monitoring is something of a silver bullet.

    Since 1970, the world’s fish population has plummeted, to the point that today 35% of commercial stocks are overfished. Meanwhile, an estimated 11% of U.S. seafood imports come from illegal, unreported and unregulated fishing, according to the U.S. International Trade Commission.

    To sustainably manage what’s left, scientists need reliable data on the activities of the tens of thousands of fishing vessels that ply the oceans every day, the vast majority with little supervision.

    Traditional tools like captain’s logbooks and dockside inspections provide limited information. Meanwhile, independent observers — a linchpin in the fight against illegal fishing — are scarce: barely 2,000 globally. In the U.S., the number of trained people willing to take underpaid jobs involving long stretches at sea in an often-dangerous fishing industry has been unable to keep pace with ever-growing demand for bait-to-plate traceability.

    Even when observers are on deck, the data they collect is sometimes skewed.

    A recent study by the National Oceanic and Atmospheric Administration found that when an observer was on deck New England skippers changed their behavior in subtle but important ways that degraded the quality of fisheries data, a phenomenon known as “observer bias.”

    “The fact is human observers are annoying,” Hager said. “Nobody wants them there, and when they aren’t being threatened or bribed, the data they provide is deeply flawed because it’s a proven fact that fishermen behave differently when they’re being watched.”

    Enter electronic monitoring. For as little as $10,000, vessels can be equipped with high-resolution cameras, sensors and other technology capable of providing a safe, reliable look at what was once a giant blind spot. Some setups allow the video to be transmitted by satellite or cellular data back to shore in real time — delivering the sort of transparency that was previously unthinkable.

    “This isn’t your grandfather’s fishery anymore,” said Captain Al Cottone, who recently had cameras installed on his 45-foot groundfish trawler, the Sabrina Maria. “If you’re going to sail, you just turn the cameras on and you go.”

    Despite such advantages, video monitoring has been slow to catch on since its debut in the late 1990s as a pilot program to stop crab overfishing off British Columbia. Only about 1,500 of the world’s 400,000 industrial fishing vessels have installed such monitoring systems. About 600 of those vessels are in the U.S., which has been driving innovation in the field.

    “We’re still in the infancy stages,” said Brett Alger, an official at NOAA charged with rolling out electronic monitoring in the U.S.

    The stakes are especially high in the Western and Central Pacific Ocean — home to the world’s largest tuna fishery. Observer coverage of the Pacific’s longline fleet, which numbers around 100,000 boats, is around 2% — well below the 20% minimum threshold scientists say they need to assess a fish stock’s health. Also, observer coverage has been suspended altogether in the vast region since the start of the coronavirus pandemic, even though the roughly 1 billion hooks placed in the water each year has barely ebbed.

    “Right now we’re flying blind,” said Mark Zimring, an environmental scientist for The Nature Conservancy focused on spreading video monitoring to large-scale fisheries around the world. “We don’t even have the basic science to get the rules of the game right.”

    The lack of internationally-accepted protocols and technical standards has slowed progress for video monitoring, as have the high costs associated with reviewing abundant amounts of footage on shore. Hager says some of those costs will fall as machine learning and artificial intelligence — technology his company is experimenting with — ease the burden on analysts who have to sit through hours of repetitive video.

    Market pressure may also spur faster adoption. Recently, Bangkok-based Thai Union, owner of the Red Lobster restaurants and Chicken of the Sea tuna brand, committed to having 100% “on-the-water” monitoring of its vast tuna supply chain by 2025. Most of that is to come from electronic monitoring.

    But by far the biggest obstacle to a faster rollout internationally is the lack of political will.

    That’s most dramatic on the high seas, the traditionally lawless waters that compromise nearly half the planet. There, the task of managing the public’s resources is left to inter-governmental organizations where decisions are taken based on consensus, so that objections from any single country are tantamount to a veto.

    Of the 13 regional fisheries management organizations in the world, only six require on-board monitoring — observers or cameras — to enforce rules on gear usage, unintentional catches and quotas, according to a 2019 study by the Paris-based Organization for Economic Cooperation and Development, which advises nations on economic policy.

    Among the worst offenders is China. Despite boasting the world’s largest fishing fleet, with at least 3,000 industrial-sized vessels operating internationally, and tens of thousands closer to home, China has fewer than 100 observers. Electronic monitoring consists of just a few pilot programs.

    Unlike in the U.S., where on-water monitoring is used to prepare stock assessments that drive policy, fisheries management in China is more primitive and enforcement of the rules spotty at best.

    Last year, China deployed just two scientists to monitor a few hundred vessels that spent months fishing for squid near the Galapagos Islands. At the same time, it has blocked a widely backed proposal at the South Pacific Regional Fisheries Management Organization to boost observer requirements

    “If they want to do something they definitely can,” said Yong Chen, a fisheries scientist whose lab at Stony Brook University in New York hosts regular exchanges with China. “It’s just a question of priorities.”

    Hazards faced by observers are highest outside U.S. waters, where electronic monitoring is used the least. Sixteen observers have died around the world since 2010, according to the U.S.-based Association for Professional Observers.

    Many of the deaths involve observers from impoverished South Pacific islands working for low pay and with little training and support — even when placed on American-flagged vessels that are subject to federal safety regulations. Such working conditions expose observers to bribery and threats by unscrupulous captains who themselves are under pressure to make every voyage count.

    “It’s in our best interest to have really professional data collection, a safe environment and lots of support from the (U.S.) government,” said Teresa Turk, a former observer who was part of a team of outside experts that in 2017 carried out a comprehensive safety review for NOAA in the aftermath of several observer fatalities.

    Back in the U.S., those who make their living from commercial fishing still view cameras warily as something of a double-edged sword.

    Just ask Scott Taylor.

    His Day Boat Seafood in 2011 became one of the first longline companies in the world to carry an ecolabel from the Marine Stewardship Council — the industry’s gold standard. As part of that sustainability drive, the Fort Pierce, Florida, company blazed a trail for video monitoring that spread throughout the U.S.’ Atlantic tuna fleet.

    “I really believed in it. I thought it was a game changer,” he said.

    But his enthusiasm turned when NOAA used the videos to bring civil charges against him last year for what he says was an accidental case of illegal fishing.

    The bust stems from trips made by four tuna boats managed by Day Boat to a tiny fishing hole bound on all sides by the Bahamas’ exclusive economic zone and a U.S. conservation area off limits to commercial fishing. Evidence reviewed by the AP show that Taylor’s boats were fishing legally inside U.S. waters when they dropped their hooks. But hours later some of the gear, carried by hard-to-predict underwater eddies, drifted a few miles over an invisible line into Bahamian waters.

    Geolocated video footage was essential to proving the government’s case, showing how the boats pulled up 48 fish — swordfish, tuna and mahi mahi — while retrieving their gear in Bahamian waters.

    As a result, NOAA levied a whopping $300,000 fine that almost bankrupted Taylor’s business and has had a chilling effect up and down the East Coast’s tuna fleet.

    When electronic monitoring was getting started a decade ago, it appealed to fishermen who thought that the more reliable data might help the government reopen coastal areas closed to commercial fishing since the 1980s, when the fleet was five times larger. Articles on NOAA’s website promised the technology would be used to monitor tuna stocks with greater precision, not play Big Brother.

    “They had everyone snowballed,” said Martin Scanlon, a New York-based skipper who heads the Blue Water Fishermen’s Association, which represents the fleet of around 90 longline vessels. “Never once did they mention it would be used as a compliance tool.”

    Meanwhile, for Taylor, his two-year fight with the federal government has cost him dearly. He’s had to lay off workers, lease out boats and can no longer afford the licensing fee for the ecolabel he worked so hard to get. Most painful of all, he’s abandoned his dream of one day passing the fishing business on to his children.

    “The technology today is incredibly effective,” Taylor said. “But until foreign competitors are held to the same high standards, the only impact from all this invasiveness will be to put the American commercial fishermen out of business.”

    Airplane crash in Gulf of Mexico leaves 2 dead, 1 missing

    [ad_1]

    VENICE, Fla. — A private airplane crashed into the Gulf of Mexico off the Florida coast Saturday night, with two people confirmed dead as authorities searched for a third person believed to have been on the flight, police said.

    Authorities in Venice, Florida, initiated a search Sunday after 10 a.m. following a Federal Aviation Administration inquiry to the Venice Municipal Airport about an overdue single-engine Piper Cherokee that had not returned to its origin airport in St. Petersburg, Florida.

    Around the same time, recreational boaters found the body of a woman floating about 2.5 miles (4 kilometers) west of the Venice shore, city of Venice spokesperson Lorraine Anderson said in a statement.

    Divers from the Sarasota County Sheriff’s Office located the wreckage of the rented airplane around 2 p.m. about a third of a mile offshore, directly west of the Venice airport, Anderson said.

    Rescuers found a deceased girl in the plane’s passenger area. A third person, believed to be a male who was the pilot or a passenger, remained missing Sunday, Anderson said.

    The county sheriff’s office, the U.S. Coast Guard, the Sarasota Police Department, Florida Fish and Wildlife Conservation Commission and the District 12 Medical Examiner’s Office and the National Transportation Safety Board were involved in the investigation, Anderson said.

  • Magnitude 7 quake shocks Solomon Islands but no major damage

    Magnitude 7 quake shocks Solomon Islands but no major damage

    [ad_1]

    WELLINGTON, New Zealand — A powerful magnitude 7.0 earthquake rattled the Solomon Islands Tuesday afternoon, overturning tables and sending people racing for higher ground.

    There were no immediate reports of widespread damage or injuries. An initial tsunami warning was withdrawn after the threat passed.

    Government spokesperson George Herming said he was in his office on the second floor of a building in the capital, Honiara, when the quake rocked the city. He said he crawled underneath his table.

    “It’s a huge one that just shocked everybody,” Herming said.

    “We have tables and desks, books and everything scattered all over the place as a result of the earthquake, but there’s no major damage to structure or buildings,” he said.

    Herming said the Solomon Islands, which is home to about 700,000 people, doesn’t have any big high-rises that might be vulnerable to a quake. He said there was some panic around the town and traffic jams as everybody tried to drive to higher ground.

    Freelance journalist Charley Piringi said he was standing outside near schools on the outskirts of Honiara when the quake sent the children running.

    “The earthquake rocked the place,” he said. “It was a huge one. We were all shocked, and everyone is running everywhere.”

    The quake’s epicenter was in the ocean about 56 kilometers (35 miles) southwest of Honiara at a depth of 13 kilometers (8 miles), according to the U.S. Geological Survey.

    The Pacific Tsunami Warning Center initially warned of possible hazardous waves for the region but later downgraded a tsunami warning as the threat passed.

    The Solomon Islands sits on the Pacific Ring of Fire, a arc along the Pacific Ocean rim where many volcanic eruptions and earthquakes occur.

  • Remote undersea volcano likely erupting in Pacific Ocean

    Remote undersea volcano likely erupting in Pacific Ocean

    [ad_1]

    HONOLULU — A volcano is likely erupting deep beneath the Pacific Ocean in the U.S. Commonwealth of the Northern Mariana Islands, but scientists don’t know for sure because it’s so inaccessible.

    All indications are that the Ahyi Seamount began erupting in mid-October, the U.S. Geological Survey said Monday. The Northern Marianas are about 3,800 miles (6,115 kilometers) west of Honolulu.

    Scientists are looking to see if the activity is shallow earthquakes or if material exploded from the crater, said Matt Haney, a USGS research geophysicist. Scientists are checking satellite data to see if there’s discolored water, which could suggest material is coming out of the volcano, he said.

    “There’s nothing right now that suggests that this eruption will intensify and become a large eruption,” Haney said.

    Still, mariners would want to avoid the immediate area, he said.

    Activity from an undersea volcanic source was picked up last month by hydroacoustic sensors some 1,400 miles away (2250 kilometers) at Wake Island.

    With help from the the Laboratoire de Geophysique in Tahiti and data from seismic stations in Guam and Japan, scientists analyzed the signals to determine the source of the activity was likely Ahyi Seamount, the USGS said in a statement.

    Activity has been declining in recent days, the statement said.

    Ahyi seamount is a large conical submarine volcano. Its highest point is 259 feet (79 meters) below the surface of the ocean. It’s located about 11 miles (18 kilometers) southeast of the island of Farallon de Pajaros, also known as Uracas.

    “There are no local monitoring stations near Ahyi Seamount, which limits our ability to detect and characterize volcanic unrest there,” the agency said. “We will continue to monitor available remote hydrophonic, seismic, and satellite data closely.”

    The seamount is part of the Mariana Volcanic Arc, which is a chain of over 60 active volcanoes stretching over 600 miles west of and parallel to the Mariana Trench, the world’s deepest point.

  • 2022 a “record year” for carbon emissions as path to avoid worst impacts of climate change narrows: “There’s no time to wait”

    2022 a “record year” for carbon emissions as path to avoid worst impacts of climate change narrows: “There’s no time to wait”

    [ad_1]

    The burning of fossil fuels continues to wreak havoc on Earth’s stability. A group of more than 100 scientists has determined that 2022 will be a “record year” for carbon emissions — a finding that comes as world leaders gather in Egypt at COP27 to discuss the urgency in minimizing global warming to prevent the worst outcomes of climate change. 

    Carbon dioxide is the primary greenhouse gas created by human activities, making its emissions a major contributor to global warming. The burning of fossil fuels overwhelmingly contributes to its increased concentrations, and international agencies and scientists have urged that such activities must be significantly reduced — and fast — to prevent excessive warming.  

    This report shows that such prompts have been unsuccessful. 

    Global carbon dioxide emissions dropped at the onset of the pandemic in 2020, but rebounded in 2021. This year, they are expected to increase another 1% to reach a level above those seen in 2019, making 2022 a “new record year” for fossil CO2 emissions. Emissions specifically from coal, oil and gas are expected to be above levels seen in 2021. 

    The Global Carbon Project published the findings.

    Those increased emissions have raised the atmospheric concentrations of carbon dioxide. This year, the concentration shows an average of 417.2 parts per million (ppm), an increase from last year’s record high. The last time carbon concentrations in the atmosphere have been this high was more than 3 million years ago.

    “This represents an increase in atmospheric CO2 of around 51%, relative to pre-industrial levels,” climate scientist Zeke Hausfather said. 

    Some regions have seen decreases in their emissions – China by 0.9% and the European Union by 0.8% – but many others are seeing significant increases. The U.S., which has long been the world’s top carbon emitter, saw its emissions increase by 1.5% this year. India, ranked No. 7 for carbon emissions, according to Carbon Brief, saw an increase of 6%. 

    The planet relies on land and ocean carbon sinks to help offset such concentrations. The “sinks” are things like plants, the ocean and soil, that absorb more carbon than they release. But Hausfather explained that they “cannot expand forever” and that they are expected to weaken over time as the impacts of climate change worsen. 

    In fact, it’s already happening. 

    Oceans, which absorb about half of carbon dioxide emissions, have had their ability to absorb CO2 reduced by about 4%, Hausfather said. 

    “If emissions continue to increase, the portion of global emissions remaining in the atmosphere – that is, the airborne fraction – will grow, making the amount of climate change the world experiences worse than it otherwise would be,” he said.  

    Matt Jones, one of the study’s authors, said that the findings do, however, offer “some hope” – the total amount of human emissions seems to be “leveling off.” 

    Land-use change emissions, primarily from deforestation, are projected to be about 10 times less than fossil fuel emissions in 2022, but Jones said that estimation comes with “the highest uncertainty,” among researchers’ other findings.

    All sources considered, 2022 emissions remain high “but approximately flat since 2015,” researchers said in a presentation, “but this trend is uncertain.” 

    And at current rates, the world is headed down a path to catastrophe. The U.N. has warned that minimizing global warming to 1.5 degrees Celsius compared to pre-industrial times seems to be no longer possible, and this report highlights its unlikelihood. Researchers said that to make that happen, no more than 380 billion tonnes of carbon dioxide – about 9 years of emissions based on 2022 numbers – can be released in the years to come. 

    Sharply decreasing carbon emissions has been a major goal of scientists and international agencies. One of the main aspects of the Paris Climate Agreement calls for net zero greenhouse gas emissions by 2050 to reduce warming to 1.5 degrees Celsius. 

    But to make that happen, the world would have to reduce carbon dioxide emissions by 1.4 billion tonnes per year, scientists of this report found. That would be the equivalent of almost completely cutting out cement production in 2021, which produced 1.67 billion tonnes of carbon emissions. 

    “We have to reduce…greenhouse gas emissions as quickly as possible,” Pierre Friedlingstein, the study’s lead author said. “…This decade through the 2030s is a time when we really have to show action and global emissions going down as quickly as possible. There’s no time to wait.”

  • US weather satellite, test payload launched into space

    US weather satellite, test payload launched into space

    [ad_1]

    LOS ANGELES — A satellite intended to improve weather forecasting and an experimental inflatable heat shield to protect spacecraft entering atmospheres were launched into space from California on Thursday.

    A United Launch Alliance Atlas V rocket carrying the Joint Polar Satellite System-2 satellite and the NASA test payload lifted off at 1:49 a.m. from Vandenberg Space Force Base, northwest of Los Angeles.

    Developed for the National Oceanic and Atmospheric Administration, JPSS-2 was placed into an orbit that circles the Earth from pole to pole, joining previously launched satellites in a system designed to improve weather forecasting and climate monitoring.

    NASA said there was no immediate data confirming deployment of the satellite’s electricity-producing solar array, but late in the day the space agency announced that it was fully extended.

    “The operations team will continue to evaluate an earlier solar array deployment issue, but at this time, the satellite is healthy and operating as expected. The team has resumed normal activities for the JPSS-2 mission,” a NASA statement said.

    The array has five panels that were collapsed in an accordion fold for launch. The fully deployed array extends 30 feet (9.1 meters).

    Mission officials say the satellite represents the latest technology and will increase precision of observations of the atmosphere, oceans and land.

    After releasing the satellite, the rocket’s upper stage reignited to position the test payload for re-entry into Earth’s atmosphere and descent into the Pacific Ocean.

    Called LOFTID, short for Low-Earth Orbit Flight Test of an Inflatable Decelerator, the device is an “aeroshell” that could be used to slow and protect heavy spacecraft descending into atmospheres, such as those of Mars or Venus, or payloads returning to Earth.

    According to NASA, effectively slowing heavy spacecraft will require greater atmospheric drag than can be created by traditional rigid heat shields that fit within the shrouds that surround payloads aboard rockets.

    The LOFTID shield inflates to about 20 feet (6 meters) in diameter.

    In the thin atmosphere of Mars, for example, having such a large shield would begin slowing the vehicle at higher altitudes and reduce the intensity of heating, according to the space agency.

    Video showed the inflated heat shield separate from the rocket and descend toward Earth. A camera aboard a recovery vessel a few hundred miles east of Hawaii showed the it splash down under a parachute.

    NASA said the shield was picked up by the boat, which then headed to recover a backup data module that was ejected during the descent.

    Section of destroyed shuttle Challenger found on ocean floor

    [ad_1]

    CAPE CANAVERAL, Fla. — A large section of the destroyed space shuttle Challenger has been found buried in sand at the bottom of the Atlantic, more than three decades after the tragedy that killed a schoolteacher and six others.

    NASA’s Kennedy Space Center announced the discovery Thursday.

    “Upon first hearing about it, it brings you right back to 1986,” said Michael Ciannilli, a NASA manager in charge of the remains of both lost shuttles, Challenger and Columbia.

    In a NASA interview, he said it’s one of the biggest pieces of Challenger ever found in the decades since the accident.

    Divers for a TV documentary crew first spotted the piece in March while seeking wreckage of a World War II plane. NASA recently verified through video that the piece was part of the shuttle that broke apart shortly after liftoff on Jan. 28, 1986. All seven on board were killed, including the first schoolteacher bound for space, Christa McAuliffe.

    The remnant is more than 15 feet by 15 feet (4.5 meters by 4.5 meters); it’s likely bigger because part of it is covered with sand. Because of the presence of square thermal tiles, it’s believed to be from the shuttle’s belly, officials said.

    The fragment remains on the ocean floor just off the Florida coast near Cape Canaveral, as NASA determines the next step. It remains the property of the U.S. government.

    Ciannilli said the families of all seven Challenger crew members have been notified.

    A History Channel documentary detailing the discovery airs Nov. 22.

  • Italy backs down on 3 migrant ships, 4th heads to Corsica

    Italy backs down on 3 migrant ships, 4th heads to Corsica

    [ad_1]

    ROME — A European humanitarian group said Wednesday its migrant rescue ship was heading to the French island of Corsica in hopes France will offer its 234 passengers a safe port, as a diplomatic standoff intensified after Italy relented and allowed migrants from three other rescue ships to disembark on Italian soil.

    The European Commission added to the pressure to find a safe port for the Ocean Viking, issuing a statement late Wednesday demanding that the passengers — some of whom have been at sea for nearly three weeks — be allowed to immediately disembark “at the nearest place of safety.”

    The statement was unusual since the Commission hasd remained quiet on the drama all week, refusing to get involved except to restate that it’s up to member countries to handle search and rescue operations and disembarkation matters, not Brussels.

    Italian Premier Giorgia Meloni had jumped the gun and announced Tuesday that France had agreed to take the Ocean Viking in, even though the government had made no such pledge publicly. As of late Wednesday, France still had not offered a port, but Francesco Creazzo of the SOS Mediterranee group said the Norwegian-flagged ship was hoping it would eventually do so.

    Officials in both Corsica and the French port city of Marseille said they would gladly take them in.

    Meloni’s premature announcement of a French agreement prompted the French government spokesman to publicly criticize the Italian maneuvering on public radio Wednesday.

    Spokesman Olivier Veran told France Info radio that the Ocean Viking “is intended to be welcomed in Italy” since it was in Italian territorial waters and said Italy’s refusal to allow passengers to disembark was “unacceptable.”

    Since Italy is the top beneficiary of the European Union financial solidarity system, he demanded that “Italy plays its role and respects its European commitments.”

    By late Tuesday, the remaining passengers on three other humanitarian-operated ships that Italy had initially refused to take in had disembarked at Italian ports. The last was the Humanity 1, operated by the SOS Humanity group, which disembarked its 35 passengers in the Sicilian port of Catania.

    There was no immediate explanation for Italy’s U-turn, but legal experts and the humanitarian groups noted that under maritime law, all people found at sea in distress are entitled to access the closest safe port where they can then apply for asylum.

    Meloni’s hard-right government had initially only allowed migrants deemed “vulnerable” to disembark, and intended to send the rest of the passengers back out to sea. But the two ships that docked at Catania for the vulnerability selection process — the Humanity 1 and the Geo Berents — refused to leave port.

    Italian news reports on Wednesday quoted Meloni as telling her Brothers of Italy lawmakers that she found it “surreal” that doctors who visited the migrants on the docked ships Tuesday had declared them all fragile and at risk of psychological distress — presumably the medical determination that allowed for them all to disembark. Meloni insisted the passengers were migrants, not shipwreck survivors.

    Interior Minister Matteo Piantedosi had adopted measures saying the flag country of each charity-operated ship was responsible for providing a safe port, not Italy. Charity groups, however, said the measure patently violated maritime law and some had launched legal action against the government.

    “We are relieved that the people can go ashore and that all those rescued from distress at sea have finally been assigned a place of safety, as required by maritime law,” said SOS Humanity’s Till Rummenhohl, who is in charge of ship operations for the Humanity 1. “However, we are appalled by the blatant disregard of the law and of human rights by Italian authorities.”

    Meloni was defiant about Italy’s hard line. In the statement prematurely announcing a French decision to open its port to the Ocean Viking, she said it was important to “continue this line of European collaboration with the countries most exposed to find a shared solution.”

    “The immigration emergency is a European issue and must be dealt with as such, with full respect of human rights and the principle of legality,” she said.

    In Marseille, Mayor Benoit Payan urged the government in Paris to open a port to the Ocean Viking and said his city would be honored to take the migrants in.

    “The castaways, children, women and men aboard the Ocean Viking, must be rescued,” he tweeted.

    “France must open a port urgently and assume its responsibilities,” Payan said. “Marseille, faithful to its history, is ready.”

    Corsica, too, said it was prepared to do its part.

    “It’s a simple and a basic duty of humanity,” tweeted Gilles Simeoni, president of the executive council on the French Mediterranean island.

  • Climate Questions: Who is most vulnerable to climate change?

    Climate Questions: Who is most vulnerable to climate change?

    [ad_1]

    Most of the world’s population has been affected in some way by climate change — 85% of the world, in fact. But the effects of climate change haven’t been equally felt by all. Some communities have seen a slight rise in temperature here and there, but others have had their entire communities wiped out.

    As the rise of global temperatures and sea-level continues to affect the world with increasingly frequency and intensity, who are the most vulnerable to the effects of climate change?

    ———

    EDITOR’S NOTE: This story is part of an ongoing series answering some of the most fundamental questions around climate change, the science behind it, the effects of a warming planet and how the world is addressing it.

    ———

    The answer is clear, according to climate scientists, climate and environmental justice experts and international research efforts on the question. The Intergovernmental Panel on Climate Change found in a 2022 report that vulnerability to climate change is “exacerbated by inequity and marginalization linked to gender, ethnicity, low income or combinations thereof.”

    “(The) poor, ethnic minorities, and women are very clearly the most vulnerable to the impacts of climate change that we are already seeing today: heat waves; displacement and smoke due to fires; and price shocks due to supply chain interruptions, higher energy prices,” Daniel Kammen, a professor of energy at the University of California, Berkeley and a coordinating lead author on IPCC reports, told The Associated Press.

    These populations are the most vulnerable to the effects of climate change because of racism, sexism and pursuit of profits over protection of people, according to Bineshi Albert, co-executive director of the Climate Justice Alliance.

    “Due to the continued search for profits by our current economic system and (by) the fossil fuel industry in particular, there are entire neighborhoods that are deemed worthy of becoming sacrifice zones, and this breaks down every time around race, class, and national lines,” she said.

    Research also shows that disabled people are more vulnerable to effects of climate change than abled bodied people.

    The increased vulnerability to climate change experienced by these populations and who is to blame for causing these inequities have become increasing topics of conversation at the international level. Debate about loss and damage — the climate harm caused by some nations to others, how much and what should be done about it — has waged on since at least COP23.

    A study published in July 2022 found that richer nations like the U.S. caused climate harm to poorer countries.

    In terms of repairing damage already caused to vulnerable populations and countries and helping them become less vulnerable, experts told the AP that it starts with including them in developing policies.

    “A natural start is to develop policies to target these underserved communities with enhanced attention and support,” Kammen said.

    Albert said it should go a step further with direct economic investments in communities most vulnerable to climate change.

    “Economic resources should go directly to those on the frontlines of the climate crisis to develop and implement their own community-led solutions,” she said. “Communities rather than profits must be the motive if we are truly going to solve the climate crisis.”

  • ‘Bubble barrier’ among finalists for Prince William’s prize

    ‘Bubble barrier’ among finalists for Prince William’s prize

    [ad_1]

    LONDON (AP) — A bubble barrier that prevents plastic waste from reaching the ocean is one of 15 initiatives named as finalists for the year’s Earthshot Prize, a global competition aimed at finding new ways to protect the planet and tackle climate change.

    Prince William, the heir to the British throne, unveiled the finalists on Friday. The five winners, who will be announced next month in Boston, will receive 1 million pounds ($1.1 million) to develop their ideas and scale up their projects.

    The prince and his charity, the Royal Foundation, launched the prize in 2020 inspired by U.S. President John F. Kennedy’s 1962 “Moonshot” speech that challenged Americans to go to the moon by the end of the decade.

    William described the finalists as “visionaries” who offer reasons to be optimistic about the planet’s future.

    “They are directing their time, energy and talent towards bold solutions with the power to not only solve our planet’s greatest environmental challenges, but to create healthier, more prosperous, and more sustainable communities for generations to come,” he said in a statement.

    Among the finalists are The Great Bubble Barrier, a Dutch invention that pumps air through perforated tubes installed in riverbeds and canals to create a curtain of bubbles designed to push plastic up to the surface and into a waste collection system.

    This removes plastic from the waterways and prevents it from reaching the ocean, “where it is nearly impossible to capture and remove,” the promoters say.

    A startup from Kenya aims to provide cleaner burning stoves to make cooking safer and reduce indoor air pollution. It was the brainwave of Charlot Magayi, who grew up in one of Nairobi’s largest slums and sold charcoal for fuel. When her daughter was severely burnt by a charcoal-burning stove in 2012, she developed a stove that uses a safer fuel made from a combination of charcoal, wood and sugarcane.

    The stoves cut costs for users, reduce toxic emissions and lower the risk of burns, Magayi says.

    Other projects include Fleather, a project in in India that creates an alternative to leather out of floral waste; Hutan, a conservation project in Malaysia to protects orangutans; and SeaForester, a cutting-edge seaweed farming effort meant to restore the ocean’s forgotten forests.

  • Ian ruins man-made reefs, brings algae bloom to Florida

    Ian ruins man-made reefs, brings algae bloom to Florida

    [ad_1]

    FORT MYERS, Fla. (AP) — Hurricane Ian not only ravaged southwest Florida on land but was destructive underwater as well. It destroyed man-made reefs and brought along red tide, the harmful algae blooms that kill fish and birds, according to marine researchers who returned last week from a six-day cruise organized by the Florida Institute of Oceanography.

    Researchers who used the cruise to study marine life in the Gulf of Mexico following the hurricane say it left in its wake red tide and destroyed artificial reefs from as far away as 30 miles (48 kilometers) from the coast of southwest Florida.

    “The one-time vibrant reefs are now underwater disaster sites themselves,” said Calli Johnson, safety dive officer for the research cruise. “Where there used to be a complete ecosystem, there are now only fish that were able to return after swimming away.”

    Before the Category 4 storm made landfall a month ago, southwest Florida had a reputation for being one of the best saltwater fishing destinations in the U.S. Saltwater and freshwater fishing in Florida has an economic impact of around $13.8 billion, according to the Florida Fish and Wildlife Conservation Commission.

    “Time will tell how this affects our greater economy, because changes in the fishing industry and tourism will come from changes in our underwater world,” Johnson said.

    The marine researchers on the cruise found high counts of the naturally-occurring algae that causes red tide offshore Punta Gorda, Boca Grande and southwest of Sanibel Island. It will be several weeks before researchers can analyze water samples that were collected to determine the threat to sea life off the Florida coast.

    The red tide outbreak also is threatening manatees off Sarasota and Charlotte counties that rely on seagrass for food, according to the Ocean Conservancy.

    “Florida is at a crossroads, with a record number of manatees dying,” said J.P. Brooker, director of Florida conservation for the Ocean Conservancy. “We must keep this issue at the forefront, so leaders statewide will invest in solutions to improve water quality—protecting natural habitats to save our beloved manatees.”

    Through mid-October, there have been 719 manatee deaths recorded by Florida wildlife officials. There were 982 manatee deaths last year.
