Temperature profile data were collected from XBT casts in the North Pacific Ocean and other locations from 23 February 1990 to 15 August 1990. Data were collected by the Scripps Institute of Oceanography (SIO) Voluntary Observing Ship Program (VOSP). 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 and other platforms in the Bering Sea and other Sea areas from 25 February 1987 to 27 July 1987. Data were collected by the National Ocean Service (NOS) with support from the Equatorial Pacific Ocean Climate Studies (EPOCS) project. 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.

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.

Temperature profiles were collected from XBT casts from the HMAS MELBOURNE and other vessels in the Indian Ocean from 01 January 1991 to 31 December 2001. Data were collected by the Royal Australian Navy and submitted by the Australian Oceanographic Data Centre in support of World Ocean Circulation Experiment (WOCE) and the Global Temperature-Salinity Pilot Project (GTSPP).

Temperature profile data were collected using bathythermograph (BT/XBT) casts from BARTLETT in the Atlantic Ocean from December 6, 1975 to September 30, 1978. Data were submitted by Woods Hole Oceanographic Institution (WHOI) as part of the International Decade of Ocean Exploration / combination of USSR POLYGON project and US MODE (IDOE/POLYMODE) project. 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.

Temperature profile data were collected using bathythermograph (BT/XBT) casts from CHAIN in the Atlantic Ocean from May 25, 1973 to June 7, 1973. Data were submitted by Woods Hole Oceanographic Institution as part of the International Decade of Ocean Exploration / Mid-Ocean Dynamics Experiment (IDOE/MODE) project. 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.

Temperature profiles were collected from XBT casts in the South Atlantic Ocean from R/V GAUSS and other platforms. Data were collected in support of the World Ocean Circulation Experiment (WOCE), Gulf of Mexico NOAA/NMFS Ship of Opportunity (SOOP), and the Global Temperature-Salinity Pilot Project (GTSPP). Data were submitted by Bundesamt für Seeschifffahrt und Hydrographie and were collected from 01 January 1999 to 31 December 2001.

Temperature profile and water depth data were collected using BT and XBT casts from the ALASKA, MORNING STAR, and PAT SAN MARIE in the Northwest Pacific Ocean and Bering Sea. Data were collected from 08 June 1985 to 16 September 1986 by National Marine Fisheries Service (NMFS) in Seattle. Data has been processed by NODC to the NODC standard Bathythermograph (XBT) (C116) format. The C116/C118 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 record was comprised of pairs of temperature-depth values. Unlike the MBT Data File, in which temperature values were recorded at uniform 5 m intervals, the XBT data files contained 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. With special instruments, measurements can be obtained to 1830 m. Prior to July 1994, XBT data were routinely processed to one of these standard types. XBT data are now processed and loaded directly in to the NODC Ocean Profile Data Base (OPDB). Historic data from these two data types were loaded into the OPDB.

Physical data were collected from XBT casts from a World-Wide Distribution from 31 March 1985 to 24 November 1990. Physical parameters include temperature profiles. Data are in the Marine Environmental Data Service (MEDS) format.

The following was present prior to current abstract edit but does not conform to digital data. This record contains Sofar float (subsurface drifter) data collected during the GUSREX (GUlf Stream Recirculation EXperiment) in the Northern Atlantic. There were 41 deployments from April 30 to December 31, 1980. The data was collected over a period of 6 years from April 30, 1980 to April 24, 1986. The floats were deployed at 700 and 2000 m depths. Additional parameters measured were temperature and pressure. These data were submitted by Dr. Phil Richardson, Woods Hole Oceanographic Institution (WHOI). The data is currently available in the C116 Bathythermograph file format of NODC.
