• Description:
  In August 2016, an acoustic seafloor survey using three different sonar systems was conducted along strong gradients of groundfish abundance, as determined from many years of Alaska Fisheries Science Center’s (AFSC) Resource Assessment and Conservation Engineering (RACE) Division bottom-trawl survey catches at fixed stations. The survey corresponded to a portion of the Bering Sea trawl stations utilized by RACE Division. The goal was to use quantitative analysis of the resulting acoustic backscatter to develop a relationship between habitat characteristics and fish abundance. The survey was conducted aboard the National Oceanic and Atmospheric Administration (NOAA) ship Fairweather. This report details the data acquisition and processing routines of the Klein 7180 side scan sonar, one of the three sonars utilized during the survey effort.
