3. Preliminary report of sound-speed contrast and density of krill measured on board RV Kaiyo Maru

   Abstract:  The target strength (TS) of Antarctic krill, Euphausia superba, is a scaling factor to ... convert the acoustic backscattering strength into the population density. Therefore, it is important to ... improve the accuracy and precision of the TS value. Since in situ and experimental TS measurements of ... small animals like krill are difficult, the theoretical scattering models are used to predict the ...

9. Influence of krill availability on humpback whale breeding success

   Abstract:  The abundance of the Antarctic krill (Euphausia superba) has been declining in the ... western Antarctic Peninsula (WAP), probably as a consequence of the effects of the considerable increase ... in the sea surface temperature observed in the region. Thus, the performance (reproduction and ... survival) of the krill consumers may be compromised. In the present study, we investigated the reproductive ...
