☆ DEEP is building underwater habitats to ‘make humans aquatic’
▼ + stars: | 2024-09-18 | by ( Amy Gunia | ) edition.cnn.com time to read: +11 min

Last week, DEEP announced a precursor to the Sentinel, a smaller underwater habitat which the company will use to develop systems for the Sentinel but will also be released as a separate product. An underwater habitat placed on the seabed near the wreck could have served as a base for divers instead, said Wolpert. OAR/National Undersea Research Program (NURP)Aquarius replaced Hydrolab after it was decommissioned. OAR/National Undersea Research Program (NURP)Dennison, of the University of Maryland, said Hydrolab was damp, cramped, lacked indoor plumbing, and had only three beds for four occupants. Wolpert said that DEEP is more than a habitat, it’s also a platform for engaging the next generation.

Great Barrier Reef, Australia CNN —As the early-morning sun rises over the Great Barrier Reef, its light pierces the turquoise waters of a shallow lagoon, bringing more than a dozen turtles to life. CNN witnessed bleaching on the Great Barrier Reef in mid-February, on five different reefs spanning the northern and southern parts of the 2,300-kilometer (1,400-mile) ecosystem. “It’s a die-off,” said Professor Ove Hoegh-Guldberg, a climate scientist at the University of Queensland in Australia and chief scientist at The Great Barrier Reef Foundation.

☆ Coral bleaching: Ocean heat is driving a mass bleaching event, and it could be the worst on record
▼ + stars: | 2024-04-15 | by ( Rebecca Wright | ) edition.cnn.com time to read: +6 min

CNN —Coral reefs around the world are experiencing a mass bleaching event as the climate crisis drives record-breaking ocean heat, two scientific bodies announced Monday — with some experts warning this could become the worst bleaching period in recorded history. If ocean temperatures don’t return to normal, bleaching can lead to mass coral death, threatening the species and food chains that rely on them with collapse. Professor Ove Hoegh-Guldberg, a climate scientist specializing in coral reefs based at the University of Queensland in Australia, predicted this mass bleaching event months ago. In February, scientists at the Coral Reef Watch program at NOAA added three new alert levels to the coral bleaching alert maps, to enable scientists to assess the new scale of underwater warming. Bex Wright/CNNIn mid-February, CNN witnessed extensive coral bleaching on Australia’s Great Barrier Reef – the world’s largest coral reef system – on five different reefs spanning the northern and southern areas.

CNN —The southern Great Barrier Reef is suffering from extensive coral bleaching due to heat stress, the reef’s managers said Wednesday, raising fears that a seventh mass bleaching event could be unfolding across the vast, ecologically important site. Jonas Gratzer/LightRocket/Getty ImagesThe Great Barrier Reef’s managers plan to extend aerial and in-water surveys across the entire reef over the coming weeks. Hotter ocean temperatures caused severe mass bleaching at the Great Barrier Reef in 2016, 2017 and 2020. Last year, the UNESCO World Heritage Committee decided not to add the Great Barrier Reef to its list of sites “in danger,” despite scientific evidence suggesting the risk of another mass bleaching event. Greenpeace’s Ritter said that following the decision, “the Australian government promised to do everything it can to protect the Great Barrier Reef.

Scientists gathered 105 instances of baleen whales performing a strange behavior called kelping. This could be to help the whales exfoliate, or for them to entertain themselves, researchers said. The group gathered over a hundred videos and photos from social media of whales "kelping", which led them to realize that this behavior isn't isolated to one group of baleen whales.

Tiny but bountiful, Antarctic krill make up one of the planet’s largest biomasses, nourishing everything from fish to marine mammals and seabirds. At Steinberg’s lab, researchers are examining how warming oceans — Antarctic krill need water colder than 4 degrees Celsius (39 Fahrenheit) to survive — are altering krill’s life cycle. However, a leading marine biologist the industry once relied on to burnish its environmental credentials has since denounced krill fishing. She accepted with the hope that she could help mitigate the effects of krill fishing on the Antarctic ecosystem. Today, she believes that krill fishing should be banned.

WELLINGTON, New Zealand (AP) — The tiny Pacific island nation of Niue has come up with a novel plan to protect its vast and pristine territorial waters — it will get sponsors to pay. “Niue is just one island in the middle of the big blue ocean,” Tagelagi said. It's one of the smallest countries in the world, dwarfed by an ocean territory 1,200 times larger than its land mass. Under the plan, the sponsorship money — called Ocean Conservation Commitments — will be administered by a charitable trust. Simon Thrush, a professor of marine science at New Zealand's University of Auckland who was not involved in the plan, said it sounded positive.

☆ Oceans absorb 90% of the heat from climate change — here's why record ocean temps are so harmful
▼ + stars: | 2023-08-16 | by ( Catherine Clifford | In Catclifford | ) www.cnbc.com time to read: +22 min

"Over 90 percent of the excess energy on earth due to climate change is found in warmer oceans, some of it in surface oceans and some at depth." Put simply, the greenhouse gases serve to trap more heat, some of which is absorbed by the ocean," Kirtman told CNBC. In addition to the daily record on July 31, the monthly sea surface temperature for July was the hottest July on record, "by far," Copernicus said. CopernicusThese record sea surface temperatures arise from multiple factors, including the El Niño weather pattern, which is currently in effect. "These climate variations occur when sea surface temperature patterns of warming and cooling self-reinforce by changing patterns of winds and precipitation that deepen the sea surface temperature changes."

☆ Scientists find new clue in what led to megalodon’s demise

Scientists previously theorized that megalodons were warm-blooded, but the new study is the first to provide concrete evidence to that effect. From this finding, they deduced the megalodon’s average body temperature was about 27 C (80 F). Like modern great white and mako sharks, megalodons were regionally endothermic, which means they had the ability to regulate temperature in certain parts of the body, according to the study. The timing of megalodons’ extinction coincides with the cooling of the Earth’s temperature, the researchers said. But learning more about the ancient shark could still help scientists better understand the threats similar marine animals face today.

Elephant seals drift downwards in a "sleep spiral" when deep diving in the ocean, a new study found. Sleeping while deep diving allows the seals to avoid predators, scientists believe. The seals fall into sleep during deep dives of up to 377 meters, which is around 1,235 feet, to avoid predators. "This is not light sleep but real paralytic, deep sleep that would have humans snoring. The recordings showed the diving seals going into a sleep stage known as "slow-wave sleep" before transitioning into REM sleep, which leads to a kind of "sleep spiral" or sleep paralysis, experts found.

Then she attached them to 13 juvenile female elephant seals that are part of a colony at Año Nuevo State Park in Pescadero, California. In shallow waters, the elephant seals even reached the seafloor, where they would rest. During REM sleep, elephant seals enter a "sleep spiral." Elephant seals sleep the most along the coast and near their foraging grounds, and that data could be used to see how shipping traffic could affect the seals.

SYDNEY, April 3 (Reuters) - Fish have been caught more than 5 miles (8 kilometres) under the surface of the ocean for the first time ever - and filmed even deeper - by a joint Japanese-Australian scientific expedition. The snailfish, of the Pseudoliparis belyaevi species, are the first to be caught below 8,000 metres, the expedition said. It wasn't immediately clear how big the fish were, but the species has been recorded as reaching a length of close to 11 centimetres (4.3 inches). "The Japanese trenches were incredible places to explore; they are so rich in life, even all the way at the bottom," said Jamieson, founder of the Minderoo-UWA Deep Sea Research Centre.

"I have been a gondolier for 28 years, and I have never seen so many low tides at once," he added. "Low water levels in Venice are unheard of, especially at this time of the year," said Giovanni Cecconi, the president of the Venice Resilience Lab. "During low tides we could use the barriers to stop the water from getting out of the lagoon," he said. However, Claudio Scarpa, the director general of the Venetian Hoteliers Association, said the low tides did bring some benefits.

For more than 70 days this summer, a marine heatwave cooked the waters of the western Mediterranean. "We've been witnessing marine heatwaves during the last 20 years," said Garrabou, who's also coordinator of the T-MEDNet marine monitoring network.

As the world warms, marine heatwaves are expected to become more frequent, according to the U.N. Intergovernmental Panel on Climate Change. Though economists have yet to account fully for the impacts of marine heatwaves, recent experience has many concerned.

Suddenly, a third orca rises from the depths, carrying a 9-foot-long great white shark in its mouth. Great white sharks are considered apex predators, meaning they have no known predators; however, researchers have identified rare occurrences of them being preyed upon by orcas. The researchers noted carcasses of dead great whites had been washing ashore with their livers ripped out and, for some, without their hearts.
