"My son found this helmet floating here in Prince William Sound."
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.
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.
