We will conduct an ichthyoplankton survey in the Bering Sea in the vicinity of Unimak Island, Alaska. This work is needed to describe larval fish and zooplankton assemblages in the Bering Sea - basin, slope, outer shelf, middle shelf - in spring. In particular, this area is a known spawning ground for walleye pollock, northern rocksole, Greenland halibut, and Alaska plaice, and abundances of larvae at this time of year are high. Data on physical characteristics of the water column will also be collected. Satellite tracked drifters may be released in the Unimak Island and/or Bering canyon vicinities to study depth-discrete current trajectories.
