    • STD data from ALPHA HELIX and REDOUBT in the Gulf of Alaska from 1983-10-14 to 1984-11-03 (NCEI Accession 8500003)

    Metadata Updated: December 1, 2025

    The University of Alaska is responsible for this data which was collected aboard the R/V Alpha Helix cruise HX65 between 10/29/84 - 11/03/84 by Dr. Royer of the Institute of Marine Science, and aboard the R/V Redoubt cruise RT41 between 10/14/83 - 10/24/83 by Dr. Burrell of the Institute of Marine Science. There were a total of 125 stations in the Gulf of Alaska area and 65 stations in the Boca de Quadra area. Data has been processed by NODC to the NODC standard High-Resolution CTD/STD (F022) format.

    The F022 format contains high-resolution data collected using CTD (conductivity-temperature-depth) and STD (salinity-temperature-depth) instruments. As they are lowered and raised in the oceans, these electronic devices provide nearly continuous profiles of temperature, salinity, and other parameters. Data values may be subject to averaging or filtering or obtained by interpolation and may be reported at depth intervals as fine as 1m. Cruise and instrument information, position, date, time and sampling interval are reported for each station. Environmental data at the time of the cast (meteorological and sea surface conditions) may also be reported. The data record comprises values of temperature, salinity or conductivity, density (computed sigma-t), and possibly dissolved oxygen or transmissivity at specified depth or pressure levels. Data may be reported at either equally or unequally spaced depth or pressure intervals. A text record is available for comments.
