BASIS survey acoustics, 2008-2010 (B59)
The 2008-2010 Bering-Aleutian Salmon International Survey (BASIS) surveys were conducted on the Bering Sea shelf (~30 m to 500 m depth ranges) in August-October aboard the RV Oscar Dyson and FV Epic Explorer. Survey extent varied among the years. Acoustic data (Oscar Dyson - 18, 38, 70, 120, and 200...
