EK60 Water Column Sonar Data Collected During SE1107

Description

Comparison of fishery-independent methods for sampling Main Hawaiian Islands Bottomfish assemblages (SE1107, 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, a TOAD (tethered optical assessment device) camera, and an AUV. 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. Simultaneous AUV and active acoustics were operated to assess whether AUV can be used to optically validate acoustic data. Bottomfishing off the Sette were conducted simultaneously with acoustics data collection for groundtruthing of acoustics data.
