DY 13-06 SeaCAT Data

The objectives of this cruise were to conduct an ichthyoplankton survey and process studies in the region between the Shumagin Islands and Shelikof Strait and then from SE Kodiak to the Kenai Peninsula 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 27-year time series of environmental and biological conditions in Shelikof Strait. In addition to this sampling, 43 stations selected from the grid for the GOA-IERP research project were occupied on the shelf break as well as on the NE side of Kodiak Island to acquire larval fish of five target species (sablefish, walleye pollock, Pacific cod, arrowtooth flounder, and Pacific Ocean perch). 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.
