Water temperature, salinity, dissolved oxygen concentration, and others taken by CTD and Niskin bottles from the Canadian Coast Guard Service ship Sir Wilfrid Laurier in the Northern Bering Sea to Chukchi Sea from 2017-07-14 to 2017-07-22 (NCEI Accession 0221778)

The Pacific sector of the Arctic Ocean is experiencing major reductions in seasonal sea ice extent and increases in sea surface temperatures. One of the key uncertainties in this region is how the marine ecosystem will respond to seasonal shifts in the timing of spring sea ice retreat and/or delays in fall sea ice formation.

Variations in upper ocean water hydrography, planktonic production, pelagic-benthic coupling and sediment carbon cycling are all influenced by sea ice and temperature change. To more systematically track the broad biological response to sea ice retreat and associated environmental change, an international consortium of scientists have developed a coordinated Distributed Biological Observatory(DBO) that includes selected biological measurements at multiple trophic levels, along with satellite and mooring measurements.
