Data were collected in the Gulf of Alaska by the University of Alaska; Institute of Marine Science (UAK/IMS) from 05 May 1989 to 28 May 1989. Data were collected in support of the Exxon Oil Spill Monitoring Program funded by the State of Alaska and the Gulf of Alaska Recirculation Project funded by the National Science Foundation, Grant #OCE8608125. Data were processed by NODC to the NODC standard F022 High-Resolution CTD/STD Output 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. This dataset is available to the public for a wide variety of uses including scientific research and analysis.
