Chukchi Sea Hydrographic (CTD) Data from the R.V. Alpha Helix Cruise, September 1996
In an international collaborative effort, Japanese, Russian, and U.S. scientists collected hydrographic CTD (conductivity, temperature, density) samples in the Chukchi Sea north of the Bering Strait during the R.V. Alpha Helix cruise between 31 August and 27 September 1996. The CTD data were converted from the format used by the Institute for Marine Studies, University of Alaska Fairbanks, to standard Seabird format.
The data collection contains values for water depth, pressure, temperature, potential temperature, conductivity, salinity, sigma-t, sigma-theta, fluorescence, transmissometer output, oxygen probe O2 concentrations, geopotential anomaly, dynamic height, specific volume anomaly, and buoyancy.
