3DY09 SeaCAT Data

공공데이터포털

Examine the interactions among climate, weather, and the recruitment of fishes in the eastern Bering Sea. We will conduct ichthyoplankton and zooplankton surveys in the waters along the eastern Aleutian Island chain, the Alaska Peninsula, and the Pribilof Islands. This work is needed to describe larval fish assemblages and determine how physical and biological factors affect the transport and survival of fish larvae.

6MF06 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. Limited beam trawling activities may also be conducted to study settlement and nursery areas for age-0 flatfishes.

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.

5MF05 SeaCAT Data

공공데이터포털

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.

4MF07 SeaCAT Data

공공데이터포털

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.

1MF08 SeaCAT Data

공공데이터포털

We will conduct bottom trawl sampling in Bering Canyon to collect ripe adult Greenland halibut (Reinharditus hippoglossides), and we will conduct an ichthyoplankton survey in the same vicinity to collect ichthyoplankton. This work is needed to describe Greenland halibut spawning ecology, as well as the distribution of eggs and larvae over the slope and in Bering Canyon in winter. The work will also be used in the study of transport and early life history of this species. Data on physical characteristics of the water column will also be collected. We will also deploy 2 oceanographic instrumentation moorings, one in Bering Canyon and one on the EBS shelf in the vicinity to Unimak Island.
