7MF06 SeaCAT Data

공공데이터포털

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.

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.

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).

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.

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.

2DY10 SeaCAT Data

공공데이터포털

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

Fisheries-Oceanography Coordinated Investigations (FOCI) is an effort by National Oceanic and Atmospheric Administration (NOAA) and associated academic scientists. FOCI's goal is to understand the effects of abiotic and biotic variability on ecosystems of the North Pacific Ocean and Bering Sea in order to discern the physical and biological processes that determine recruitment variability of commercially valuable finfish and shellfish stocks in Alaskan waters. We will focus our efforts on the physical, chemical, and biological processes occurring in particular areas of this region. These include Portlock Bank, Stevenson Trough, and one of the large offshore eddies, that typically impact this area between April and September and contribute to on and offshore fluxes.
