The submersible was exploring the Thwaites Glacier to study its potential effects on sea-level rise. Ran's disappearance is a tragic loss for climate change research as scientists were using the autonomous machine to study the melting activity of Thwaites Glacier, also known as the "Doomsday Glacier." AdvertisementThat's why Wåhlin and her team chose Ran to check out Thwaites Glacier because it's actively melting. The Thwaites Glacier is one of the largest in the world and could raise global sea levels significantly if it collapses entirely.

Scores of sea turtles stunned by cold temperatures along the North Carolina coast have died, officials said. The North Carolina State University Center for Marine Sciences and Technology took in 109 cold-stunned sea turtles from Cape Lookout on Sunday, but only 36 survived, the center said in a social media post this week. Cape Hatteras National Seashore said more than 100 cold-stunned sea turtles were also found in recent days along the shoreline between Bodie Island and Ocracoke. Most of the turtles were taken to the North Carolina Aquarium on Roanoke Island’s Sea Turtle Assistance and Rehabilitation center, officials said in a in a social media post. The wind carries the lethargic turtles to the shorelines, which are monitored in cold weather by volunteers and seashore biologists.

☆ How to cook mussels at home
▼ + stars: | 2023-09-17 | by ( Casey Barber | ) edition.cnn.com time to read: +6 min

How to prepare musselsRemember that mussels are alive until you cook them, and they need to stay alive and breathing until they’re ready to hit the pan. If you won’t be cooking and eating your mussels immediately, use the colander method as noted above to store the mussels until you’re ready to use them. How to cook musselsUnlike oysters, which take a bit of practice and skill to shuck, it’s simple to steam mussels. Add the cleaned mussels, cover the pot and cook for about 8-10 minutes until all the mussels have opened. • Mussels in tomato-garlic broth• Spanish mussels with hard chorizo and cream• Beer-steamed mussels• White wine and olive oil-steamed mussels• Mussels in coconut milkCasey Barber is a food writer, artist and editor of the website Good Food Stories.

☆ 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."

☆ Rare octopus discovery made 2 miles below the ocean surface
▼ + stars: | 2023-06-30 | by ( Katie Hunt | ) edition.cnn.com time to read: +6 min

CNN —On a rocky outcrop almost 2 miles beneath the surface of the Pacific Ocean off Costa Rica, researchers have documented an active octopus nursery. The discovery of an active community of octopus moms and babies solved a mystery that had perplexed scientists. We saw babies being born.“The researchers also found one other smaller octopus nursery on a low-temperature hydrothermal vent on an as-yet-unnamed seamount. Scientists believe this octopus is potentially a new species of Muusoctopus, a genus of small to medium-size octopus. The scientists also plan to return to the site in December to collect octopus eggs from devices they deposited recently to find out why the creatures like to brood there.

☆ Black Sea urchins have disappeared from the Gulf of Aqaba. Their loss could kill off an entire coral reef
▼ + stars: | 2023-06-02 | by ( Hadas Gold | ) edition.cnn.com time to read: +8 min

Black sea urchins. The epidemic only affects the black sea urchins, and was even killing them in the research lab's tanks, and Eilat's aquarium -- which all use freshly circulating seawater. Black sea urchins feed on the algae that grows on the reef. The first step, needed in the coming weeks, is to establish "broodstock populations" that will eventually help repopulate and reintroduce the black sea urchins into the region. But the surviving sea urchins that could be used to do so are themselves under threat.

☆ Elephant seals amaze scientists with their ability to sleep 1,200 feet deep under the ocean to avoid predators
▼ + stars: | 2023-04-22 | by ( Isobel Van Hagen | ) www.businessinsider.com time to read: +4 min

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.

☆ Elephant seals enter 'sleep spiral' during ocean dives

The researchers refer to this as a “sleep spiral.”The research marked the first time scientists recorded brain activity in free-ranging wild marine mammals, capturing data from 104 sleep dives. 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.

☆ Gondolas left stranded as Venice's canals run dry

Gondolas are pictured in the Grand Canal during a severe low tide in the lagoon city of Venice, Italy, March 17, 2022. "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. A 2016 marine heatwave along Chile's southern coast caused huge algae blooms that wiped out fish farms and cost the aquaculture industry some $800 million, said scientist Kathryn Smith with the Marine Biological Association of the United Kingdom. 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.
