The abundance and distribution of euphausiids and zero-age pollock on the inner shelf of the southeast Bering Sea relative to the inner front. Deep-Sea Research
Acoustic data and net samples were collected during late spring and early fall 1997–1999 to assess zooplankton and micronekton abundance and distribution relative to the Inner Front at three sampling grids (Port Moller, Cape Newenham and Nunivak Island) on the inner shelf of the southeast Bering Sea...
