Temperature profile data collected with XBTs in the South Atlantic aboard the R/V Knorr during the Ajax Expedition from 1983-10-09 to 1984-02-18 (NCEI Accession 8900205)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 27, 2026 | Last Modified: 2023-02-14T00:00:00.000+00:00
This dataset includes selected depth bathythermograph (SBT) data from R/V Knorr in the North Atlantic Ocean, South Atlantic Ocean, and Southern Ocean from 1983-10-09 to 1984-02-18. Data has been processed by NODC to the NODC standard Selected Depth Bathythermograph (SBT) (C125) 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.
