The primary objective of the cruise was the recovery and deployment of moorings in the Bering Sea. The second objective was physical oceanographic property sampling at and near the mooring locations.

To recover and deploy surface and subsurface oceanographic instrumentation moorings at several locations in the Bering Sea. To complete CTD casts and plankton tows at sampling stations in and around the mooring locations and along the 70 meter isobath. To collect data on the physical, chemical and biological parameters at each sampling station.

To recover and deploy several surface and subsurface oceanographic instrumentation moorings at PMEL historical mooring sites BS-2 and BS-4. To complete CTD casts and bongo tows at specified Bering Sea locations.

The primary objective of this cruise will be mooring operations – including recoveries, deployments and searches - in the Gulf of Alaska and Bering Sea. Additionally, there will be biological sampling at mooring sites and the 70 m isobath line. A SBE 19Plus was deployed synoptically with gear used to sample icythoplankton and zooplankton at these locations. 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.

The primary objectives of this cruise will be to deploy and recover moorings in several locations in the Gulf of Alaska and the Bering Sea. Upon leaving Seward, 5 moorings will be deployed in the Gulf of Alaska in and around Gore Point. A SBE 19Plus was deployed synoptically with gear 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.

The primary objective is to conduct an assessment of eggs and larvae of walleye pollock (Theragra chalcogramma) over the eastern Bering Sea shelf. We will also 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 cruise is a collaboration between two AFSC Programs, The Fisheries Oceanography Coordinated Investigations Program (FOCI) and the Ecosystem Monitoring and Assessment Program (EMA).

The objectives of this cruise are to conduct an ichthyoplankton survey and process oriented studies in the region between Unimak Pass, the Shumagin Islands, and through Shelikof Strait to Kodiak Island, Alaska, so that we may estimate the abundance, transport, and factors influencing the survival of young walleye pollock larvae. We will also occupy stations on Line 8 to continue our 18-year time series of environmental and biological conditions in Shelikof Strait. In the event of high algal concentrations encountered at a survey station in the strait region and in the sea valley region, sampling will be conducted for a forage fish diet study.

Eco-FOCI 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 - outer shelf, middle shelf - in the spring. In particular, this area is a known spawning ground for walleye pollock, northern rocksole, Pacific cod, 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 will be released in the Unimak Island vicinity to study depth-discrete current trajectories and to test an oceanographic model of water movements for use in studies of larval transport.

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.
