The dataset consists of 37 XBT casts in the region northeast of Flemish Cap. The XBTs were Lockheed Martin Sippican Deep Blue probes with a nominal depth range of 760 m. The MK21 data acquisition system was used to log the raw data and the standard depth equation was used to determine probe depth. The data were subsequently bin-averaged into 1 m bins. The XBT data were collected during R/V Knorr cruise KN200-2 to the region northeast of Flemish Cap in the Northwest Atlantic. The purpose of the cruise was to observe the process of anticyclonic eddy generation and evolution in the so-called Northwest Corner region, where the northward-flowing North Atlantic current turns to flow eastward. During the cruise the upper ocean hydrography, in an approximately 250 km square region centered on the turning region, was observed with a grid of CTD casts to 1000 db spaced approximately 50 km apart. The XBT was deployed at roughly the midpoints of some of the transits between CTD stations and at other locations in the region.

Temperature profile data were collected using bathythermograph (BT/XBT) casts from ENDEAVOR in the Atlantic Ocean from May 8, 1978 to May 25, 1978. Data were submitted by University of Rhode Island; Graduate School of Oceanography as part of the INTERNATIONAL DECADE OF OCEAN EXPLORATION / combination of USSR POLYGON project and US MODE (IDOE/POLYMODE) project. Data were processed by NODC to the NODC standard Universal Bathythermograph Output (UBT) format. The UBT 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.

Temperature profile data were collected using bathythermograph (BT/XBT) casts from OCEANUS in the Atlantic Ocean from November 29, 1978 to December 10, 1979. Data were submitted by Woods Hole Oceanographic Institution (WHOI) as part of the International Decade of Ocean Exploration / combination of USSR POLYGON project and US MODE (IDOE/POLYMODE) project.

Temperature profile data were collected using bathythermograph (BT/XBT) casts from CHAIN in the Atlantic Ocean from January 22, 1975 to February 2, 1975. Data were submitted by Woods Hole Oceanographic Institution (WHOI) as part of the International Decade of Ocean Exploration / Mid-Ocean Dynamics Experiment (IDOE/MODE) project. Data were processed by NODC to the NODC standard Universal Bathythermograph Output (UBT) format.

Data has been processed by NODC to the NODC standard Bathythermograph XBT Selected Depths (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.
