    • Conductivity, Temperature and Depth (CTD) and water quality data from NOAA LAUNCHES from Cook Inlet, Gulf of Alaska, from 1993-06-22 to 1993-08-25 (NCEI Accession 9500053)

    Metadata Updated: July 1, 2025

    The Conductivity, Temperature and Depth (CTD) and other data were collected in Gulf of Alaska. Data was collected from NOAA LAUNCHES. The data was collected over a period spanning from June 22, 1993 to August 25, 1993. Data was submitted by Dr. Douglas Segar of University of Alaska, Anchorage, AK.

    This accession contains files with hydrocarbon, trace metal, and grain size analyses for the U.S. MMS report (OCS Study MMS 95-0009) Current Water Quality in Cook Inlet, Study. There are 9 Lotus 123 WK3 files, 1 Lotus 123 WK1 file, and 1 Lotus Freelance graphics file.

    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.
