The primary objective was to conduct an assessment of eggs and larvae of Walleye Pollock (Gadus chalcogrammus) over the eastern Bering Sea shelf. The data collected will be used to examine the interactions among climate, weather, and ichthyoplankton distribution and abundance. This work is needed to describe larval fish assemblages and determine how physical and biological factors affect the transport and survival of fish larvae. The survey is a collaboration between two Alaska Fisheries Science Center (AFSC) programs, Ecosystems and Fisheries Oceanography Coordinated Investigations (Eco-FOCI), and Ecosystem Monitoring and Assessment (EMA). A SBE 49 was deployed synoptically with Bongo, CalVET and Tucker trawls used to sample icythoplankton and zooplankton at selected stations. Temperature and Conductivity were measured and Salinity and Sigma-T were derived from these measurements. While the SeaCAT measures values on the down and upcasts, only the upcasts are used.
