Summary
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
kHz; Epic Explorer - 38 kHz) were collected along transects between surface
trawl stations. One or two midwater trawls were performed each day to identify
targets observed on the acoustics. These data sets were analyzed using the 38
kHz acoustic data and midwater+surface trawl data for species or group
assignment. Data are presented as integrated water column backscatter (i.e.,
acoustic energy summed within depth categories) within 0.5 nmi horizontal bins
for species or scattering groups. Species or group assignment was made using
surface and/or midwater trawl catch composition. Data are from both day and
night periods. These data are considered to represent conservative backscatter
estimates of age-0 pollock (Pollock0), age-1 pollock (Pollock1), capelin
age-0+ (Capelin), Pacific herring (Herring), age-0 Pacific cod (PacificCod0),
age-1+ Arctic cod (ArcticCod1+), age-1+ saffron cod (SaffronCod1+),
rockfish/Atka mackeral/Pacific sandfish/sand lance/stickleback/rainbow
smelt/prowfish (Other), and unidentified, non-partitioned species (UnkFish).
Data were collected from 11 September 2008 through 04 October 2010.
