Bathythermograph (XBT) data from US Navy Ships of Opportunity in the Northeast Atlantic Ocean: 19800530 to 19800611 (NCEI Accession 8400196)

Temperature profile data were collected using XBT casts in the Northeast Atlantic Ocean from 30 May 1980 to 11 June 1980. Data were collected by the US Navy; Ships of Opportunity with support from the Gulf of Mexico NOAA/NMFS Ships of Opportunity (SOOP) project. 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.
