December 1, 2022 — There is danger lurking on the floor of the Bering and Chukchi seas for mussels, snails, clams, worms and other cold-water invertebrates, according to a new study led by National Oceanic and Atmospheric Administration scientists.
If climate change continues its current trajectory, the Bering and Chukchi seafloor areas will be too warm for those creatures by the end of the century.
In turn, that means trouble for walruses and other marine species. Snails and mussels are particularly important to commercially harvested fish like halibut and yellowfin sole, along with being prey for the Pacific walruses that gather in the summer in the northern Bering and southern Chukchi seas. The Bering Sea is part of the North Pacific Ocean south of the Bering Strait that separates Alaska from Russia, while the Chukchi Sea is part of the Arctic Ocean just north of the strait.
