Carcasses of seals were found in cities Kotlik, Kotzebue, Kivalina, and the Islands of Stuart and the St. Lawrence. While scientists analyze samples.

Some of the dead animal was without hair. Experts are trying to figure out whether it happened in the decomposition of, or was caused by an abnormal shedding that was observed during another mass death of seals in the 2011-2016 years. Then failed to install by the deaths of 657 individuals.
