Temperature profile data collected using XBT and other instruments from KNORR and other platforms in Northeast Atlantic Ocean from 1983-02-03 to 1984-10-22 (NCEI Accession 8600146)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 29, 2026 | Last Modified: 2023-02-11T00:00:00.000+00:00
Temperature profile data were collected using XBT, BT, and AXBT casts from the KNORR and other platforms in the Northeast Atlantic Ocean. Data were collected from 03 February 1983 to 22 October 1984 by Lamont - Doherty Earth Observatory with support from the Seasonal Response of the Equatorial Atlantic Experiment / Français Ocean Et Climat Dans L'Atlantique Equatorial (SEQUAL/FOCAL) project. Data has been processed by NODC to the NODC standard Bathythermograph (XBT Aircraft) (C118) and Bathythermograph (XBT) (C116) formats. 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 C116/C118 format contains temperature-depth profile data obtained using expendable bathythermograph (XBT) instruments.
