Map shows selected posts from LEO Network. This map was developed for the One Health Group meeting on December 6, 2022, and contains time and location specific environmental events (unusual or significant) from either first person observations and local news articles. This map includes selected LEO Network posts between September 1 and December 6, 2022, for the geographic region above 54 degrees north latitude. Map by M. Brubaker

The number of sockeye returning to Klukshu, Yukon, to spawn began to drop off in the 1990s. This year, hundreds of the bright red fish line the small creek that winds through the village. Neither the Champagne and Aishihik First Nations nor Fisheries and Oceans Canada are sure why the fish have returned after decades of steady decline.
Biologists struggle to single out a leading cause of the caribou population’s decline. Increased wolf predation, changed migration patterns and climate warming affecting food sources can all influence the herd. “It’s going to be another rough winter again this year without caribou,” Selawik resident Norma Ballot said.
Between the fall of 2021 and the fall of 2022, APU students observed a dramatic decrease in the number of Peregrine Falcons between Eagle and Circle, Alaska.
A historically powerful storm slammed into Western Alaska Friday night and into Saturday, bringing major flooding and high winds to a huge swath of coastal communities. By Saturday evening, the state said it had received no reports of injuries or deaths related to the storm. But damage had torn across hundreds of miles of Alaska’s coastline impacting communities all along the way. Alaskans described water flooding homes and roads. Wind tore off roofs. Houses floated off their foundations. Boats sank.
Storms can bring a bounty to the beach - driftwood sometimes or in this case, clams! But be careful out there. There are new concerns about emerging levels of harmful algae in Western Alaska waters, which could impact shellfish and human health.
GOLOVIN RESIDENTS ARE IN CLEANUP MODE as their community works to restore power, phone service and clear debris. After the flood waters receded from the weekend’s severe fall storm, some locals are left with feet of sand in their homes. “At my place we’ve got three feet of sand we’re still shoveling out with the crew here, trying to get the sand out of the living area so we can get the sheetrock to go ahead and dry off,” Alaska Senator Donny Olson of Golovin said.
The heavy rains and high water from storm Murdok today and Monday are contributing to the erosion of the old landfill and river bank.
The spiders are usually in multiple form in most areas, but it has not been witnessed in this form. This is described as a spider "ballooning" event, the term used when spiders launch themselves in to the air. These events might be happening more frequently as warming Arctic temperatures has been associated with increases in the population of some spider species such as the wolf spider (see Spider Baby Boom in Warming Arctic), and spiders moving further north and also having more then one hatch per season.
During a community meeting, Chevak residents said better emergency planning should be a long-term priority. For now, though, assessing damage is the focus.
Ali Ralson was riding her 4 Wheeler towards Cape Blossom and came upon a beach full of fish. It appears that most of the fish are stickleback although there may be other species involved too. This would suggest an environmental issue that would impact multiple fish species rather than a pathogen. One potential cause could be harmful algal toxins.
Die-offs of krill are in some cases associated with hypoxia (low oxygen) excess sediment suspended in the water column and changes in water temperature. There were recent reports of high levels of Alexandrium in water samples in the areas, and Norton Sound Health Corporation is performing some testing of krill samples (see below). There was also an unprecedented storm event only a week ago, unusual for the storm surge and early season.
Forecasters say they are expecting significant coastal erosion from Utqiagvik to Unalakleet from the second severe-weather event to hit the region in three weeks.
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.
A black bear cub in Southeast Alaska was sick last month with bird flu, according to the Alaska Department of Fish and Game. The cub found in Bartlett Cove, Glacier Bay National Park and Preserve, is only the second instance of highly pathogenic avian influenza being diagnosed in a bear amid an ongoing outbreak. Health officials say risk to mammals, including people, remains low.
More than 1,000 domestic poultry and hundreds of wild birds have died or needed to be euthanized in the state since early spring. Since the first case of a deadly strain of avian flu was detected in Alaska in May, more than 1,000 domestic poultry and hundreds of wild birds have died or needed to be euthanized.
