#Algal #Toxins emerge as a new concern in #Alaska’s Northern Bering Sea

Locals who depend on the sea for food and culture are trying to understand the risks to traditional foods and wildlife populations in a region undergoing myriad changes

by Yereth Rosen, Alaska Beacon, May 31, 2026 via #ICTNews

Excerpt: "For countless generations, people of the #BeringStrait region have relied on the food they harvest from the sea without worrying about #HarmfulAlgalBlooms [#HABs] that threaten seafood eaters in warmer and more southern latitudes.

"Now, as the Northern Bering Sea undergoes cascading effects of a warming climate, algal risks pose a new challenge.

"The change has been dramatic.

"And it has prompted a change in the way #Nome youth grow up learning about collecting food from the waters around their home. In early April, Nome high school students traveled to Bethel with their science teacher, where they presented their research at the Western Alaska Interdisciplinary Science Conference held by Alaska Sea Grant.

"Algal toxins were present, at very low but detectable levels, in fish they eat.

"Sophomore Audrey Bruner-Alvanna was among the group of student researchers. She said young people are concerned about algal blooms, which proliferate in warmer conditions, and their potential effects on wild food resources.

" 'Because, you know, as the climate changes, as the world gets warmer and stuff, there’s going to be more of these toxins and stuff during summer,' she said. 'I feel like a lot of people that I’ve talked to have been wondering about how our subsistence is going to change in the future based on all of that.'

"The student research came about after one of the nation’s densest and biggest concentrations of toxin-producing Alexandrium algae ever documented burst forth in the waters of the Bering Strait region in 2022.

"Until the appearance of the 'massive bloom, the most toxic bloom, the longest-persisting bloom in the U.S.,' local people barely knew what harmful algal blooms or #Alexandrium are, said Emma Pate, president of the Nome Eskimo Community, the local tribal government.

" 'So we had to figure things out and learn really fast,' Pate said during an October 'Strait Science' presentation hosted by the University of Alaska Fairbanks’ Nome campus."

A New Idea to Save the #AMOC? Dam the #BeringStrait.
Blocking the narrow waterway between #Russia and #Alaska could help stabilize a vulnerable system of #ocean currents, scientists found.
In a study published on Friday in the journal Science Advances, the researchers show that, under certain conditions, such a #dam could prevent a collapse of a network of ocean currents, known as the AMOC, that plays a central role in regulating #Earth’s #climate.

Yes, sure, #oil. But also control of #shipping #chokepoints are the strategic assets being contested.

“Commercial whaling did not cease because the market recoiled from devouring the future of an entire species […]
Bowheads avoided extinction not because a new space opened in the accounting ledger to tally their worth alive. They survived because, in the world outside the strait, they ceased to have value at all.”

Bathsheba Demuth, Floating Coast, p.68

Beringia was 10 thousand years younger than originally believed, apparently -- and people started living there right away.

#BeringLandBridge formed surprisingly late during last #IceAge https://phys.org/news/2022-12-bering-bridge-late-ice-age.html

The #BeringStrait was flooded 10,000 years before the Last Glacial Maximum https://www.pnas.org/doi/10.1073/pnas.2206742119

The Bering Land Bridge connecting Asia to North America did not emerge until around 35,700 years ago, less than 10,000 years before the height of the last ice age. Growth of the ice sheets—and the resulting drop in sea level—occurred surprisingly quickly and much later than previous studies had suggested.

Here's another great Bering Strait photo: December 16, 2022 looking west with the helicopter from Nome on approach into Iŋaliq (Little Diomede), #Alaska. There is no runway for fixed wing aircraft at Iŋaliq. Back in the day a runway would be constructed on the #seaice once it stabilized, but those days are gone. That's Big Diomede, Russia across the way. Photo by F. Ozenna and shared with permission. #akwx #BeringStrait @brdemuth @Climatologist49
