Temperature profiles were collected from XBT casts from the YELCHO and other platforms from 08 February 1976 to 05 April 1976. Data were collected by Texas A&M University (TAMU) as part of the International Decade of Ocean Exploration / International Ocean Studies / First Dynamic Response and Kinematics Experiment in the Drake Passage (IDOE/ISOS/FDRAKE). 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 records are comprised of pairs of temperature-depth values. The XBT data files contain 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. Special instruments permit measurements to be obtained to 1830 m.
