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. Cruise information, position, date and time were reported for each observation. The data record was comprised of pairs of temperature-depth values. 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 in NW Atlantic (limit-40 W) from ships OLEANDER and SKOGAFOSS as part of Ship Of Opportunity Programme (SOOP). The data was collected from January 5, 1994 to December 19, 1994. The originator's bathythermograph (XBT) data was submitted 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 were collected in NW Atlantic (limit-40 W) from ships OLEANDER and YANKEE CLIPPER between January 11, 1992 and December 20, 1992 as part of Ship Of Opportunity Programme (SOOP). Twenty seven SOOP XBT sections containing originator's bathythermograph (XBT) data were submitted by Mr. Glenn Strout, National Marine Fisheries Service, Narragansett, RI. The data have been converted and are now available on line in C116 (XBT) file format of NODC. 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.

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.

Data has been processed by NODC to the NODC standard Bathythermograph (XBT) (C116) format.

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.

The water temperature data was collected by International Ice Patrol from April 1986 to June 1988 in the NW Atlantic. Ships Evergreen, Hornbeam, Tamaroa and Bittersweet were used to collect the data. The C116 Bathythermograph data was submitted by the US Coast Guard, Groton, CT.

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.
