Gray Whales (Eschrichtius robustus) in the Western Chukchi and East Siberian Seas
During joint Soviet-American shipboard surveys in autumn 1979 and 1980, numerous sightings of gray whales (Eschrichtius robustus) were made in the western Chukchi and East Siberian seas. Gray whales were observed well offshore in ice-free water in 1979, but near the Chukotka coast in 1980. During th...
