The water temperature and depth data in this accession was collected by Hydro Department of Birkenhead, Merseyside, UK. Three different ships were used to collect the 371 bathythermograph (XBT) observations spanning from May 19, 1983 to May 31, 1988. The data was submitted by Mr. P.F. Wainwright. The data has been processed by NODC and is available in C116 Bathythermograph (XBT) file format.

Temperature profile data were collected in NW Atlantic (limit-40 W) from ship KOELN ATLANTIC as part of the Ship Of Opportunity Programme (SOOP) and World Ocean Circulation Experiment. The data were collected from December 31, 1989 to January 1, 1991. The originator's 796 SOOP bathythermograph (XBT) data set from 14 cruises was submitted by Dr. P. Ehlers of Bundesamt für Seeschifffahrt und Hydrographie, Hamburg, Germany via File Transfer Protocol.

Temperature profile and water depth data were collected using BT and XTB casts in the NW Atlantic Ocean from the HARRIOT LANE. Data were collected from 29 December 1986 to 31 December 1986 by the US Coast Guard. 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 and water depth data were collected using BT and XBT from the HARRIOT LANE in the Northwest Atlantic Ocean and TOGA Area - Atlantic Ocean.

The water depth and temperature data was collected as part of Global Temperature- Salinity Pilot Project (GTSPP) from ship TORRENS by the Commonwealth Scientific and Industrial Research Organization and Australian Oceanographic Data Center, Potts point, New South Wales, Australia. The data was collected from June 19, 1991 to October 3, 1991. The originator's bathythermograph (XBT) data file was submitted by Mr. Andrew L. Walsh in GTSPP format via FTP.

The water depth and temperature data was collected in NW Atlantic (limit-40 W) from ships SKOGAFOSS, OLEANDER, and YANKEE CLIPPER as part of Ship Of Opportunity Programme (SOOP). The data was collected from February 6, 1993 to December 5, 1993. The originator's bathythermograph (XBT) data was received via telecommunication by National Marine Fisheries Service, Narragansett, RI. Data has been processed to the NODC standard Bathythermograph (BT) data 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.

The water depth and temperature data was collected from multiple ships by the Australian Navy. The data was collected from 1978-1991. The originator's analog bathythermograph (XBT) data was submitted in a box along with eight cassette tapes by Mr. Ben J. Searle. The data has been converted and is now available on line in C116 file format of NODC.
