Summary: | Physical, temperature profile, and other data were collected from CTD and XBT casts from the L. MCCORMICK and other platforms from 14 September 1981 to 05 March 1983. Data were collected by the National Marine Fisheries Service (NMFS) and other institutions as part of the Marine Resources Monitoring, Assessment and Prediction (MARMAP) and WARM CORE RINGS projects. Data were processed by NODC to the NODC standard High-Resolution CTD/STD Output(F022) and the Universal bathythermograph Output (UBT) formats. Full format descriptions are available from the NODC homepage at www.nodc.noaa.gov/. This 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. The UBT format contains temperature-depth profile data obtained using expendable bathythermograph (XBT) instruments. Cruise information, position, date and time were reported for each observation. The data records are comprised of pairs of temperature-depth values. The XBT data files contain temperature values at non-uniform depths. These depths were recorded at the minimum number of points ("inflection points") required to accurately define the temperature curve. Standard XBTs can obtain profiles to depths of 450 m or 760 m. Special instruments permitted measurements to 1830 m.
