Broadbandwidth sound scattering and absorption from krill (Meganyctiphanes norvegica), Mysids (Praunus flexuousus and Neomysis integer) and shrimp (Crangon crangon)
(Meganyctiphanes norvegica) over the acoustical bandwidth of 30 to 210 kHz and compared to similar scattering ... measurements made of Antarctic krill (Euphausia superba; Demer and Conti, 2003a). The measurements of total ... target strength (TTS) match the SDWBA model (Demer and Conti, 2003b) recently developed for Antarctic ... krill, indicating its validity for other euphausiids species with similar size and shape. However, the ...
