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 were collected in NW Atlantic (limit-40 W) project from R/V WIECZNO cruise WI86-01 between July 31, 1986 and September 16, 1986. The originator's bathythermograph (XBT) data was submitted on a diskette by Pat Turner, 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 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.

This dataset consists of helium and tritium data submitted by Woods Hole Oceanographic Institution (WHOI) as part of the Transient Tracers in the Ocean Funding Organization (TTO) North Atlantic Survey and NATS (North Atlantic Tracer Section) programs. The TTO data was collected during 7 legs of the R/V Knorr from April to October 1981. The NATS data was collected during legs 1-3 of the Atlantis from June to September 1981. The TTO program has reference number L00944 and the NATS program has a reference number of L00945. These programs were supported by NSF grants OCE79-21378 and OCE81-17998.

This dataset contains oceanographic temperature profiles from XBTx from the KOELN EXPRESS and WALTHER HERWIG III in the North Atlantic Ocean and coastal North Atlantic for the SHIP-OF-OPPORTUNITY PROGRAMME (SOT SOOP). These data were downloaded from Bundesamt für Seeschifffahrt und Hydrographie (BSH) Germany with permission of Detlev Machoczek, BSH, and replace data from NCEI Accession 9700167.

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.

This dataset contains contains chlorophyll data collected from 1958-1988 using multiple ships. Marine pigments, productivity, and associated chemistry data were collected in NE Atlantic (limit-40 W) and NW Atlantic (limit-40 W) as part of the Joint Global Ocean Flux Study (JGOFS). This data base has approx. 12,000 stations in JGOFS format. Any particulars on the station data can be found in JGR-Oceans, 97:2279-2293; titled The Remote Sensing of Ocean Primary Productivity. Data was submitted by William Balch, Rosenstiel School of Marine and Atmospheric Science (RSMAS), University of Miami. Also, these data have been copied onto CD-Rom at Goddard for distribution with the CZCS.

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 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 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.
