3MF08 SeaCAT Data

공공데이터포털

We will be conducting an ichthyoplankton and juvenile fish survey in the Eastern Bering Sea in the waters contiguous to the Alaska Peninsula and 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 autumn. In particular, this area is a known nursery area for walleye pollock, northern rocksole, Greenland halibut, and Alaska plaice, and abundances of larvae and juveniles at this time of year are high. Zooplankton data and data on physical characteristics of the water column will also be collected.

We will conduct an ichthyoplankton survey in the Bering Sea in the vicinity of Pribilof Canyon, Alaska. This work is needed to describe larval fish and zooplankton assemblages in the Bering Sea - basin, slope, outer shelf - in spring. In particular, this area is a potential conduit for transport larvae of slope-spawning fishes (Greenland halibut, arrowtooth flounder, rockfish) to the continental shelf. Data on physical characteristics of the water column will also be collected. Satellite tracked drifters may be released in Bering and/or the Pribilof Canyon vicinity to study depth-discrete current trajectories.

The primary objective of this cruise will be the recovery and deployment of moorings in the Gulf of Alaska and Bering Sea.

3MF02 SeaCAT Data

공공데이터포털

To conduct an ichthyoplankton survey in the Bering Sea in the vicinity of Unimak Island, Alaska. This work is needed to describe larval fish assemblages in the Bering Sea (slope, outer shelf, and middle shelf) in spring. Zooplankton data and data on physical characteristics of the water column will also be collected. The primary objective of this cruise was to examine community structure and transport of fish larvae and plankton on the continental shelf, slope, and deep water areas of the southeastern Bering Sea and Unimak Pass. Hydrographic, nutrient, and microzooplankton samples were also collected.

공공데이터포털

The late-summer FOCI cruise is designed to address biological and methodological questions regarding age-0 walleye pollock in the western Gulf of Alaska. The primary cruise objective is to map age-0 pollock density over an area of high environmental heterogeneity, and to relate variations in fish density with environmental variability to provide some insight regarding pollock habitat suitability.

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.

공공데이터포털

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 22-year time series of environmental and biological conditions in Shelikof Strait.
