Temperature profile data were collected using XBT and BT casts from NOAA Ship RESEARCHER and other platforms in a World-wide distribution from 30 September 1970 to 05 August 1979. Data were collected by the US NAVY; Ships of Opportunity. Data were processed by NODC to the NODC standard Universal Bathythermograph Output (UBT) format. 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

Temperature profiles were collected from XBT casts from NOAA Ship OCEANOGRAPHER from 13 February 1973 to 10 June 1973. Data were collected by the National Ocean Service (NOS) as part of the International Decade of Ocean Exploration (IDOE). Data were processed by NODC to the NODC standard Universal Bathythermograph Output (UBT) format. 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 permit measurements to be obtained to 1830 m.

Temperature profile data were collected using XBT and BT casts from NOAA Ship RESEARCHER in the North Atlantic Ocean from 19 April 1978 to 27 September 1979. Data were collected by the National Marine Fisheries Service (NMFS) in Highlands with support from the North East Monitoring Program. Data were processed by NODC to the NODC standard Universal Bathythermograph Output (UBT) format.
