The bottom of the Bering and Chukchi seas could become too warm for some important species

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.

Abnormally Warm Years Caused a Sea Change in Coastal Alaska Ecosystems

February 27, 2020 — Rapidly warming Alaska is already a poster child for climate change, from its vanishing sea ice to its thawing permafrost. But over the last three years, the state’s northwestern coast has experienced a series of unusual climate-related changes—remarkable even for the long-altered Pacific Arctic.

Beginning in 2017, a combination of abnormally high temperatures and unusually strong, southerly winds swept the Bering and Chukchi seas. An alarming cascade of ecological consequences ensued—record-low sea ice, shifting algae blooms, migrating fish populations and sudden seabird die-offs were just a few.

“Most of my own research is with people living in the coastal communities, so talking to them and hearing about what they’re seeing,” said Henry Huntington, an independent Alaskan researcher and consultant. “And they saw some very unusual things, and things that struck them.”

“Ridiculous” water temperatures and unstable sea ice were among the most common complaints raised in interviews with coastal residents, Huntington noted.

“Adding to that, what we’re hearing from folks on the research cruises, it just became apparent that things were really a lot different from what any of us expected,” he said.

Rarely seen Arctic seal spotted in Washington State – 2,000 miles from home

August 19, 2016 — A rarely seen pinniped that inhabits sub-Arctic and Arctic waters – from the Bering Sea north to the Chukchi Sea – has been spotted 2,000 miles from home, on a beach in Washington state.

Biologists spotted a single ribbon seal hauled out on Long Beach Peninsula on Tuesday, and captured a few images before the seal returned to the water.

The extraordinary sighting marks the second time in four years that a ribbon seal has appeared so far south of its typical range. The other was 2012, when a ribbon seal was spotted twice in the Seattle area.

After that sighting, Peter Boveng, leader of the polar ecosystem program with the National Marine Fisheries Service, told the Associated Press, “There are not many people who see these regularly.”
