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.

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.

The water depth and temperature data were collected in SW Atlantic (limit-20 W) as part of World Ocean Circulation Experiment cruise A23 from ship JAMES CLARK ROSS between March 23, 1995 and May 5, 1995. The originator's bathythermograph (XBT) data were submitted by Dr. Karen J. Heywood, School of Environmental Science, University of East Anglia; Norwich, UK.

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 water depth and temperature data was collected from ships of Opportunity The data was collected from January 4, 1989 to December 15, 1989. The originator's bathythermograph (XBT) data was submitted in a cassette by Mr. Grayson Wood of National Marine fisheries Service, Narragansett, RI. The data has been converted and is now available on line in C116 file format of NODC.

The water depth and temperature data was collected in NW Atlantic (limit-40 W) from ships OLEANDER and YANKEE CLIPPER as part of Ship Of Opportunity Programme (SOOP). The data was collected from January 5, 1991 to December 11, 1991. The originator's bathythermograph (XBT) data was submitted in a tape by Robert Benway, National Marine Fisheries Service, Narragansett, RI. The data has been converted and is now available on line in C116 file format of NODC. The data type C116 contained temperature-depth profile data obtained using expendable bathythermograph (XBT) instruments.

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 were collected in north and south Atlantic as part of World Ocean Circulation Experiment (WOCE) from four different ships between August 14, 1986 and December 4, 1986. The originator's bathythermograph (XBT) data tape containing profiles were submitted by Dr. Reiner Onken, University of Kiel, Germany. The data have been converted and are now available on line in C125 Bathythermograph-XBT-Selected Depths file format of NODC.

The water depth and temperature data was collected from five ships by the Australian and New Zealand Navy. The data was collected between August 1, 1993 and March 29, 1995. The originator's 267 analog bathythermograph (XBT) traces were submitted by Mr. Andrew L. Walsh to NODC.

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.
