Biomass and population structure of Antarctic krill (Euphausia superba DANA) collected during SIBEX II cruise of R.V. KAIYO MARU
Juvenile and adult Euphausia superba were collected in the northwest of the Antarctic Peninsula, eastern Drake Passage, and the Scotia and Weddell Seas during the SIBEX II cruise of R. V. KAIYO MARU. Average biomass estimated from blind tows was 145g/1000m^3 (838g/1000m^3,if aimed tows were included...
