Summary
Description
Temperature profiles were collected from XBT casts from the EXPORT DEFENDER and other platforms from 13 September 1977 to 22 November 1977. Data were collected by the National Marine Fisheries Service (NMFS) and other institutions part of the Marine Resources Monitoring, Assessment and Prediction (MARMAP) project. Data were processed by NODC to the NODC standard Universal Bathythermograph Output (UBT) format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/bt.html. 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 either 450 or 760 m. Special instruments permitted measurements to be obtained to 1830 m.
