  • Seals that rely on sea ice off Alaska’s northwest coast have been dying at uncommon rates, and federal marine mammal biologists Thursday declared an “unusual mortality event”.
  • The count included 85 bearded seals, 66 ringed seals, 40 spotted seals and 91 seals that were not identified.
  • NOAA Fisheries also declared an unusual mortality event following abnormal molting and deaths of ice seals and walruses from 2011 to 2016.
