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.

Temperature profile data were collected using XBT casts from the ANGO and other platforms in a world wide distribution. Data were collected from 01 January 1994 to 25 May 1994.

Temperature profiles were collected from XBT casts from the USS CURTS and other platforms from 30 April 1980 to 24 April 1986. Data were submitted by the Woods Hole Oceanographic Institution (WHOI) as part of the South Atlantic Bight 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. 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. 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.

Temperature profile data were collected using XBT and BT casts from NOAA Ship MALCOLM BALDRIGE and other platforms in a World-wide distribution from 22 June 1990 to 29 August 1991. Data were collected by the National Ocean Service (NOS) with support from the Deep Freeze 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.

Temperature profile data were collected using XBT and BT casts from NOAA Ship MALCOLM BALDRIGE in a World-wide distribution from 03 February 1988 to 31 March 1990. Data were collected by the National Ocean Service (NOS) in Rockville. 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.

XBT data were collected from MULTIPLE PLATFORMS from a World-Wide distribution from 02 January 1990 to 31 December 1995. Data were submitted by the UK Hydrographic Office and are in the Broken Serial Data Record Format (BROKEN SERD).

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.

Temperature profile data were collected using XBT and BT casts from NOAA Ship MALCOLM BALDRIGE and other platforms in a World-wide distribution from 10 March 1989 to 01 August 1990. Data were collected by the National Ocean Service (NOS) with support from the SubTropical Atlantic Climate Study (STACS) 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.

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.

Temperature profile data were collected from MBT casts from a World-Wide distribution. Data were collected from MULTIPLE PLATFORMS from 08 April 1948 to 14 December 1968. Data were processed by NODC to the NODC standard Universal Bathythermograph Output (UBT) format. This file format is used for temperature-depth profile data obtained using the mechanical bathythermograph (MBT) instrument. The maximum depth of MBT observations is approximately 285 m. Therefore, MBT data are useful only in studying the thermal structure of the upper layers of the ocean. Cruise information, date, position, and time are reported for each observation. The data record comprises pairs of temperature-depth values. Temperature data in this file are recorded at uniform 5 m depth intervals.
