2022 EcoFOCI Mooring Cruise and Hydrographic Survey

April 25, 2022

The overall research objective for both surveys is to determine how varying biological and physical factors influence the Bering Sea marine ecosystem.

Who is conducting the research?

Scientists from the Alaska Fisheries Science Center’s RACE Division and Marine Mammal Lab, as well as NOAA’s Pacific Marine Environmental Lab (PMEL), with colleagues from the University of Alaska Fairbanks, aboard the NOAA ship Oscar Dyson.

What is the research objective?

The overall research objective for both surveys is to determine how varying biological and physical factors influence the Bering Sea marine ecosystem.

The objectives of the survey:

  1. Service oceanographic and passive acoustic moorings that measure water column and sea ice properties and detect marine mammals and sounds from human activities
  2. Sample the water column for zooplankton, larval fish, and bottom-dwelling organisms
  3. Deploy drifters to measure currents
  4. Deploy sonobouys to monitor marine mammal presence in real time
