NEFSC 2010 Spring Bottom Trawl Survey (HB1002, EK60)

The NEFSC bottom trawl survey is a fisheries independent, multi-species survey that provides the primary scientific data for fisheries assessments in the U.S. mid-Atlantic and New England regions. Two bottom trawl surveys are conducted each year, one in the spring and one in the autumn. The survey is a standardized, stratified random design, with stratification based on bathymetry and multiple trawl sites within each stratum. Trawl sites are selected randomly, but the overall ship path is south to north. The survey covers the continental shelf and U.S. exclusive economic zone (EEZ) from Cape Hatteras, North Carolina into the Canadian EEZ. The primary gear is a bottom trawl, with CTD, multifrequency echosounder, and a host of other scientific sensor data collected ancillary to the bottom trawl catches.

Search Data
Distribution Formats
  • Kongsberg/Simrad instrument files (.raw or .wcd) (Version: 1)
    • File Specification: Kongsberg/Simrad .raw files are generated by ME70, EK60 or ES60 instruments. They contain power and optionally angular position data with each beam/frequency identified by an independent channel. See the Simrad interface specification manual for further information. The .wcd files are generated by Kongsberg EM302 or EM122 instruments. See Kongsberg documentation for more information.
