4DY08 SeaCAT Data

공공데이터포털

The objectives of this cruise are to conduct an ichthyoplankton survey and process oriented studies in the region between the Shumagin Islands to Shelikof Strait 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 23-year time series of environmental and biological conditions in Shelikof Strait.

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

공공데이터포털

The objectives of this cruise were to conduct an ichthyoplankton survey and process studies in the region between the Shumagin Islands and Shelikof Strait so that we could estimate the abundance, transport, and factors influencing the survival of young walleye pollock larvae. We also occupied six of the stations on Line 8 to continue our 26-year time series of environmental and biological conditions in Shelikof Strait. In addition to this sampling, stations selected from the main grid for the GOA-IERP research project were occupied to deploy the neuston gear to acquire larval fish of five target species (sablefish, walleye pollock, Pacific cod, arrowtooth flounder, and Pacific Ocean perch).

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.

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.

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.
