The absence of krill from the South Georgia zone, winter 1983

An extremely low abundance of the Antarctic krill, Euphausia superba, was observed in the Scotia Sea during the austral winter of 1983. The decline could not be attributed to any of the environmental factors investigated, including phytoplankton biomass which was higher than expected. One effect of...
