In situ target strength measurements of Antarctic zooplankton (Euphausia superba and Salpa thompsoni) at 120 khz and 200 khz, corroboration of scattering models, and a statistical technique for delineating species
both species. The individual TS measurements were collected at 120 kHz with a split-beam echosounder ... scattering is from each animal's spheroidal nucleus. Consistent with the measurements of encaged krill ... frequencies. About 15% of the tests indicated the presence of salps without krill and about 3% revealed krill ... echograms included dense swarms with virtually equivalent Sv at the two frequencies.
