US biologists eye unusual deaths of Alaska seals
ANCHORAGE, Alaska —
NOAA Fisheries have received reports of 282 dead seals in the Bering and Chukchi seas since June 1, 2018.
That’s nearly five times the average number of reported seal strandings.
The deaths have mostly occurred from June to September in both years.
Declaration of an unusual mortality event allows the agency to use more resources to investigate the deaths.
