EK60 Water Column Sonar Data Collected During SE1102L1

Comparison of fishery-independent methods for sampling Main Hawaiian Islands Bottomfish assemblages (SE1102L1, EK60). Optical, active acoustics, and research fishing data on bottomfish abundance and biomass were collected over predetermined grids to compare results of methodologies. Optical data were collected using a baited stationary Botcam. Acoustics data were collected using a narrow-beam EK60 system operating at 38, 70, and 120 kHz frequencies. Research fishing was conducted using hook-and-line on small boats. Botcam drops with simultaneous acoustic recordings were conducted to obtain target strength measurements of fish with known species and sizes. Bottomfishing off the Sette were conducted simultaneously with acoustics data collection to further groundtruth the acoustics data.

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 The scientific objective of this cruise is to collect data on economically important Hawaii semi-demersal fish abundance and biomass using three methodologies: optical, experimental fishing, and active acoustics. Based on the results, a subset of methodologies, or a single methodology will be selected to provide the best possible estimates of abundance and biomass to be applied to stock assessment models.
