This map includes selected observations posted by LEO Network members from across Alaska, between September 1 and November 30, 2022. This map was used during the quarterly LEO Network webinar held on December 13, 2022. Map by Mike Brubaker

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.
"I don’t recall seeing anything like this before."
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.
The aftermath of Typhoon Merbok left fuel tanks floating and home flooded, but locals also saw an opportunity.
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.
"I had never seen burrows like this, and they were everywhere on the Nuna. What seemed to be elaborate tunnel systems dug where there was apparently no permafrost, and sometimes the burrows led up to the bench behind."
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.
A site visit to Newtok on September 30, shows severe erosion from impacts of storm (typhoon Merbok). The images show both severe permafrost melt and river erosion.
We typically see them blooming in June and most of them have been without blooms for months.
Black insect never seen by a Yupiit of Andreafski Tribal member at his home in St. Mary's.
Hikers should be cautious when hiking the Castner Glacier trail since chunks of ice may fall and the streams and rivers are very fast.
After severe flooding from Storm Merbok, the waters have recided leaving the town digging out a giant sand box.
Permafrost thaw in Noatak is causing the condition of the grave site to degrade. A trench has formed and crosses are tipping over.
Cell phone video was taken by one resident, and the fox appears to be an Arctic fox, which is not known in this region.
