Summary
Description
The second coordinated U.S.U.S.S.R. aerial survey of walruses was completed in September 1980. The first was undertaken in September October 1975. In 1980, surveys undertaken by the U.S. side were done on 10 to 20 September. The results of this survey indicate that there were an estimated 140,000 plus walruses east of 173 W longitude at the time of the survey. A concurrent survey undertaken in regions west of 173 degrees W by Soviet scientists resulted in an estimate of 130,000 to 150,000, suggesting a total estimate of 270,000 to 290,000 Pacific walruses in 1980.
