Research Expedition to the Bering Sea - TN250
Research Vessel Thomas G. Thompson
June 17 - July 14, 2010

Updated:   July 12, 2010

      Plots and results from the Summer 2010 Bering Sea Ecosystems cruise are shown here.  This Summer expedition is funded through the BEST-BSIERP program in conjunction with NOAA's NPCREP* program, and jointly funded by NSF and NPRB.  This R/V Thomas G. Thompson cruise carries scientists from a multiple of disciplines, measuring ocean conditions and food web productivity on the eastern Bering Sea shelf. These fit into the larger directive of this multi-year project addressing the study and inter-relationship of climate, oceanography, fisheries biology, marine mammals, seabirds, and local and traditional knowledge.
      Four scientists from the EcoFOCI project are out on the ship. We are handling hydrography, water sampling, nutrients and O2 analysis. The cruise left from Dutch Harbor, Alaska in the Aleutian Islands on June 17th.
