Description:
Abstract:
The science efforts aboard the F/V Frosti as part of the Patch Dynamics Study around the Pribilof Islands, a component of the BEST/BSIERP Partnership Program, included basic hydrography, phytoplankton standing stock, zooplankton abundance, fish abundance, and fish proximate composition.
Purpose:
To quantify the forage base for fur seals and marine birds around the Pribilof Islands in the Bering Sea.

An SBE19plus CTD with an SBE 43 dissolved oxygen sensor, a WetLabs ECO-flntu fluorometer and a Wetlabs C-Star transmissometer (25 cm pathlength, 530 nm wavelength) was lowered to a depth of 100 m at the beginning and end of each 10 km long transect.
Process_Step:
Process_Description:
Data were low pass filtered and edited for loops before the raw data variables were converted to variables of interest using factory calibrations. Fluorometer calibration equations were confirmed from periodic samples of water filtered for chlrophyll in the area of the experiment.
