☆ Billions of Alaska snow crabs have starved to death because of ocean heat, study shows

CNN —Billions of snow crabs have disappeared from the ocean around Alaska in recent years, and scientists now say they know why: Warmer ocean temperatures likely caused them to starve to death. “This was a huge heat wave effect,” Aydin told CNN. “When the heat wave came through, it just created a huge amount of starvation. Climate change has triggered a rapid loss in sea ice in the Arctic region, particularly in Alaska’s Bering Sea, which in turn has amplified global warming. “2018 and 2019 were an extreme anomaly in sea ice in the Bering Sea, something that we’d never seen before,” Szuwalski said.

They come as New Jersey continues to grow as a hub of opposition to offshore wind projects from residents' groups and their political allies, mostly Republicans. The state's Democratic governor and Democratic-controlled Legislature want to make the state the East Coast leader in offshore wind energy. “Our goal is to bring offshore wind energy monitoring activities into this partnership. Opponents of offshore wind blame the deaths of 70 whales along the East Coast since December on offshore wind site preparation work. Earlier this week, Republicans in the state Senate called for a moratorium on all offshore wind projects.

☆ Sharks on a Golf Course Made a Watery Grave Unlike Any Other

For nearly two decades, the Carbrook Golf Club near Brisbane, Australia, had the ultimate water hazard: a lake teeming with bull sharks. It all started in 1996 when raging floods swept six young bull sharks from a nearby river into a 51-acre lake near the golf course’s 14th hole. When the floodwaters receded, the sharks found themselves stuck, surrounded by grassy hills and curious golfers. The sharks, according to a new study, are more than just a fluke along the fairway. In research published last month in the journal Marine and Fisheries Science, Peter Gausmann, a shark scientist and lecturer at Ruhr University Bochum in Germany, said that the cartilaginous club members of Carbrook bull sharks demonstrate that bull sharks can live indefinitely in low-salinity aquatic environments.

POINT PLEASANT BEACH, N.J. (AP) — As the U.S. races to build offshore wind power projects, transforming coastlines from Maine to South Carolina, much remains unknown about how the facilities could affect the environment. So far, four offshore wind projects have been approved by the federal government for the U.S. East Coast, according to the American Clean Power Association. The company is a Danish wind power business that will build two of the three offshore projects approved for New Jersey. Numerous others have been proposed, and the U.S. Bureau of Ocean Energy Management plans to review at least 16 offshore wind projects by 2025. The federal government has endorsed — but not required — compensation to the fishing industry for negative effects from offshore wind.

The red king crab fishery was closed; the snow crab fishery cut to a tenth of the previous year's take. After another bad survey last year, the red king crab fishery closed again and the snow crab fishery closed for the first time ever. Kevin Abena, who runs a fishing business with his father, also relies on tendering to stay afloat in the wake of the crab fishery closure. Researchers this year brought samples of crab back to Kodiak for further analysis, exploring how snow crab respond to stress in their environment, including rising heat. It will help determine what crab fisheries might open this winter and decisions on each kind of crab are expected some time in early October.

A team of scientists with the U.S. National Oceanic and Atmospheric Administration have conducted the first assessment of marine heatwaves along North America's continental shelves. Surface heatwaves can be picked up by satellites and can result in huge algal blooms. It found that while sometimes a marine heatwave can hit both the sea surface and ocean bottom at the same time, bottom heatwaves can also occur on their own. Marine heatwaves have become about 50% more frequent over the past decade. Past bottom marine heatwaves have decimated Pacific cod and snow crab populations.
