The Bering Sea’s cold pool, a critical part of the seafloor ecosystem, had shrunk to a worrying degree in recent years, but it is continuing to slowly return, according to the latest results of NOAA’s bottom trawl survey. Saffron cod, also called tomcod, seems to be bouncing back after a few bad years, and Arctic cod and blue king crab numbers were also better.

One UBC scientist says his early estimation that a billion creatures died from the 2021 heat dome was too low. Today, life is returning to areas scorched by last year’s unprecedented heat wave. The die off was patchy and the plants and animals in the intertidal zone that survived the heat wave “are the parents to the next generation,” Harley said.
This crab from the Pacific Ocean was once introduced into the Barents waters of the Soviet Union in Arctic Russia. Since then the invasive species has spread to Norway’s Barents Sea and a multi-million dollar industry has sprung up around it. In 2023 Norway exported 2,500 tons of king crab worth 1,2 billion kroner (€100 million).
