Lots of dead krill washed up on Sarichef Island
Shishmaref, Alaska, United States
30 Sep 2022
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.
