Temperature profile data were collected using bathythermograph (XBT) from the ATLANTIS 2 from the Atlantic Ocean from May 17, 1978 to June 03, 1978. Data were submitted by Woods Hole Oceanographic Institution as a part of the IDOE/POLYMODE (International Decade of Ocean Exploration / combination of USSR POLYGON project and US MODE).

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.

The accession contains water temperature and depth data collected from LEXA MAERSK and many other ships from September 1987 to April 1988. Data was collected by Scripps Institution of Oceanography, La Jolla, CA. The bathythermograph XBT data is available in C116 file format of NODC.

This dataset contains Expendable BathyThermograph (XBT) temperature profile data obtained from 278 XBTs in the Atlantic Ocean and 460 XBTs in the Indian Ocean. 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.

Temperature profile data were collected using bathythermograph (BT/XBT) casts from OCEANUS in the Atlantic Ocean from November 29, 1978 to December 10, 1979. 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. 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.

The water depth and temperature data was collected from sixty different cruises. The originator's bathythermograph (XBT) analog data collected from January 22, 1981 to September 5, 1984 was submitted in a box by Mr. Paul Stevens of Fleet Numerical Oceanography Center (FNOC), Monterey, CA. The data has been converted and is now available on line in C116 file format of NODC.

Temperature profile data were collected using bathythermograph (BT/XBT) casts from ENDEAVOR in the Atlantic Ocean from May 8, 1978 to May 25, 1978. Data were submitted by University of Rhode Island; Graduate School of Oceanography 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. 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.

Standard XBTs can obtain profiles to depths of either 450 or 760 m. With special instruments, measurements can be obtained to 1830 m.

The data in this accession was collected using seventeen different ships during twenty four different cruises between July 16, 1971 and April 30, 1990. The real time data of water temperature at varying depth bathythermograph (XBT) was recorded in stripcharts by the US Navy. One box analog XBT'S and radio log sheets was submitted by Mr. Paul Stevens of Fleet Numerical Oceanography Center, Monterey, CA to NODC. The XBT data from these stripcharts have been digitized and is present in the current NODC data storage system in C116 file format.

The bathythermograph data in this accession were collected using six different ships between November 2, 1990 and December 2, 1991. The real time data of water temperature at varying depth bathythermograph (XBT) was recorded by the US Navy. The data was submitted to NODC by Fleet Numerical Oceanography Center, Monterey CA. The XBT data has been digitized and is present in the current NODC data storage system in C116 file format.

Data has been processed by NODC to the NODC standard Bathythermograph XBT Selected Depths (SBT) (C125) format. The UBT (C125) 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. Depths are selected by the originator - usually at standard horizons or some fixed interval. Standard XBTs can obtain profiles to depths of either 450 or 760 m. Special instruments permitted measurements to be obtained to 1830 m.
