Differences in backscattering strength determined at 120 and 38 kHz for three species of Antarctic macroplankton
The ability to acoustically separate zooplankton species is an important requirement for ecological studies and to improve biomass estimates. In order to distinguish between Euphausia superba and other swarm-forming macroplankters we used a dual frequency echo-sounder (120 and 38 kHz) and echo-integ...
