Temperature profile data using XBT casts in the TOGA - Atlantic Ocean from NOAA Ship RESEARCH from 1979-07-10 to 1979-07-24 (NCEI Accession 7900278)

Temperature profile data were collected using XBT casts from NOAA Ship RESEARCHER in the TOGA - Atlantic Ocean from 10 July 1979 to 24 July 1989. Data were submitted by the Atlantic Oceanographic and Meteorological Laboratory in Miami, Florida with support from the First Global GARP (Global Atmospheric Research) 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 file format is used for temperature-depth profile data obtained using expendable bathythermograph (XBT) instruments. Standard XBTs can obtain profiles at depths of about 450 or 760 m. With special instruments, measurements can be obtained to 1830 m. Cruise information, position, date, and time are reported for each observation. The data record comprises pairs of temperature-depth values. Unlike the MBT data file, in which temperature values are recorded at uniform 5m intervals, the XBT Data File contains temperature values at non-uniform depths. These depths are at a minimum number of points ("inflection points") required to record the temperature curve to an acceptable degree of accuracy. On output, however, the user may request temperature values either at inflection points or interpolated to uniform depth increments.
