A comparison between the estimated density of krill from an acoustic survey with that obtained by scientific nets on the same survey
Abstract: This work presents the initial comparative analysis of acoustic and net haul krill ... part of a hydroacoustic biomass survey for Antarctic krill in CCAMLR Division 58.4.1. The acoustic ... krill density estimates were consistantly larger than the net estimates, otherwise no relationship was ... between acoustic and net krill density estimates.
