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.

    Purpose Scientists from the Midwater Assessment and Conservation Engineering (MACE) Program of the Alaska Fisheries Science Center's (AFSC) Resource Assessment and Conservation Engineering (RACE) Division routinely conduct acoustic-trawl (AT) stock assessment surveys to estimate the distribution and abundance of walleye pollock (Theragra chalcogramma). The summer 2011 cruise onboard NOAA Ship Oscar Dyson was conducted from June 9, 2011 to August 9, 2011 in the western-central Gulf fo Alaska. Acoustic data was collected using Simrad EK60 scientific echosounder and Simrad ME70 multibeam echosounder systems mounted on the hull of the Oscar Dyson. The purposes of the cruise included the collection of acoustic and trawl data necessary to determine the distribution, biomass, and biological composition of walleye pollock and other major fish species; calibrate the EK60 and ME70 acoustic systems using standard sphere calibration techniques; collect physical oceanographic data (temperature and salinity profiles) at selected sites, and continuously collect sea surface temperature and salinity data; conduct trawl hauls (AWT, PNE, and Methot) to ground truth multi-frequency echo integration data collection; collect data on fish distributions and school characteristics and the seafloor using the ME70 multibeam echosounder.
