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.
After alerting the region to very high levels of harmful algal blooms west of Kotzebue and Gambell two weeks ago, scientist onboard the research vessel Norseman II have found even higher numbers of Alexandrium catenella algae cells near Wales, Diomede and Shishmaref.
High concentrations of harmful algae called Alexandrium catenella have been detected in the Bering Strait waters near St. Lawrence Island, Wales, and Little Diomede, posing a potential danger to human health and urging caution when consuming certain seafood.
A research vessel, Norseman II, was trapped in unusually dense sea ice for 14 days off the Seward Peninsula coast during a Pacific walrus study, but is now en route to Nome for repairs.
On Sunday, Nomeites noticed that their internet wasn’t working and that cell service was spottier than usual. Large fiberoptic line was damaged by sea ice deep underneath the moving sea ice above.
On Sunday night, a plump ringed seal pup was spotted on the ice in front of Breaker’s Bar on Nome’s Front Street. UAF Alaska Sea Grant agent Gay Sheffield was called and moved the pup to a more secluded beach. The ice had likely gone out too fast and the mother finished up the normal weaning process on the ice chunks in front of Nome.
St. Lawrence Island, home to two native villages in the region, is also the summer home of several migratory seabird species, including kittiwakes, auklets, murre and shearwaters. Over the last several years, though, the bird colonies on the island have been shrinking, and no one has been able to determine why.

Researchers stepping off the research vessel Norseman II in Nome last weekend, brought significant news of having found very high concentrations of a phytoplankton called Alexandrium catenella in regional waters. Alexandrium is an algae that can produce saxitoxins, which can cause dangerous paralytic shellfish poisoning in people. The scientists issued an advisory, notifying Norton Sound Health Corporation, UAF Sea Grant and the Alaska Division of Public Health.
High winds that pushed water high up on south facing shores of the Seward Peninsula cause shoreline erosion on the Chukchi Sea coast of Shishmaref, last week.
Graves at the historic St. Michael cemetery in Alaska are eroding due to increased storms and erosion, prompting an archaeologist to recover exposed remains and coordinate efforts to re-bury them. Tom Wolforth’s prime mission was to appropriately handle the remains and make sure they could be reburied. He has been working closely with the tribe and the municipality to address their concerns. One concern, Martin said, was that these exposed remains could pose a risk of disease, especially if the dead had been buried during the time of the 1918 flu pandemic. But Wolforth assured them that if properly handled this shouldn’t be a problem.
Increasing blanket of mucus-like substance in water threatens coral and fishing industry
El Bosque, a Mexican fishing village with a population of 400 people, is being swallowed by rising sea levels, and experts predict that the entire village could be underwater within a year, leaving residents displaced and without adequate housing alternatives.
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.
Rising sea temperatures may mean prey swimming in deeper water out of reach of guillemots, razorbills, puffins and kittiwakes
Fuel shipments normally take place during autumn from departure ports such as Murmansk and Arkhangelsk. However, last fall saw a sudden freeze-up and quickly accumulating sea-ice on the Northern Sea Route, including the Kara Sea. Of the two rescued barges, one contained 7,000 tons of diesel fuel, while the other was loaded with 170 tons of kerosene.
A humpback whale named Stanislav was successfully freed from a fishing net in a first-of-its-kind rescue operation in Russia's Barents Sea.
King and snow crab populations in the Bering Sea have plummeted ahead of the harvest season, some by 99% compared to previous years.
Health and animal control officials on the Island are warning that possible avian flu, specifically highly pathogenic avian influenza (HPAI), may have infected hundreds of dead cormorants that have been found on Martha’s Vineyard beaches. On Wednesday, the state issued a press release saying that there has been an increase in shorebird deaths statewide, with …
If upwelling starts a month earlier than usual, the amount of oxygen, already low, has to last until the fall when storms promote mixing which adds oxygen back into the system. As of late September this year, upwelling is still occurring and low levels of oxygen are still persisting.
