3. A study on calibration for commercial echosounder using the bottom backscattering strength from a fishing vessel near the South Shetland Islands in Antarctic

   Abstract:  In this study, we calibrated a commercial echosounder (ES70) installed on a krill ... fishing vessel to use it in estimating biomass of Antarctic krill (Euphausia superba). The method ... . 38kHz and 120kHz were used for the calibration, and krill swarm signals, obtained from multi frequencies ... by bottom backscattering strength, since the proportion of krill swarm signals within 2 dB < S V120kHz‒38 ...
