Researchers from Stony Brook University and the Southwest Fisheries Science Centre (SWFSC) conducted the first multi-year survey of the Antarctic krill (Euphausia superba) population in coastal waters near Livingston Island in Antarctica.

They used smaller vessels that allow access to shallow, nearshore waters, and also found that these had less interannual variation than offshore waters. The findings were published in the July issue of the Canadian Journal of Fisheries and Aquatic Sciences.
