Summary
Description
Temperature profiles were collected from XBT casts from the DELTA NORTE from 20 July 1974 to 16 August 1974. Data were collected by the Delta Steamship Co. as 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 450 m or 760 m. Special instruments permitted measurements to 1830 m.
