Whale Survey in Alaska

Randomized aerial surveys were flown between 26 July and 26 August 1984 to search for cetaceans in two areas of southwestern Alaska on both Bering Sea and Pacific Ocean sides of the Aleutian  Islands. Sightings were made of gray whales, fin whales, minke whales, beaked whales, killer whales and harbor porpoises. The low number of whales in the survey indicated that populations were still depressed due to prior whaling activity in the area.
