2009-2010 Bottom-Anchored Moorings

In a collaborative effort between University of Alaska Fairbanks (UAF) and University of Washington (UW), this data set addresses the impact of physical variability on the processes and structure of the Bering shelf ecosystem, with special emphasis on how freshwater redistributed by the shelf circulation or introduced from sea ice modifies stratification and nutrient distributions. In particular, the effort seeks to understand how changes in sea ice affect advection and mixing; how variable fluxes of low-salinity, nutrient-deficient (but iron-rich) coastal waters affect production; how cross-shelf fluxes are established and altered; how these fluxes might respond to climate change; how the seasonal stratification cycle is controlled; and how the buoyant coastal flow evolves. This ocean mooring data set, consisting of 9 moorings, was collected during a Bering Sea ice cruise on the R/V Point Sur . These data are collected from the UW instruments on the deepest moorings of the C-line and S-line deployed in 2009, labeled C55-09 and S55-09. The data were collected from 10 July 2009 through 28 July 2010. Note: ADCP bottom track direction corrected and updated on November 20, 2014
