An outline of narrowband echosounder survey methods to estimate biomass of Antarctic krill in CCAMLR Division 58.4.1 during 2018/19 season by the Japanese survey vessel, Kaiyo-maru
Abstract: Japanese multidisciplinary survey with a focus on biomass estimation of Antarctic krill ... CCAMLR standard will be employed in the analysis but utility of 70 kHz data will also be investigated ... . Measurements of acoustic impedances (mass density and sound-speed contrasts) of krill will also be conducted ... during the survey.
