Temperature profile data collected using XBTs from the SEAPAC BUNKER HILL and other platforms from the Pacific Ocean during the International Decade of Ocean Exploration / North Pacific Experiment (IDOE/NORPAX) project, 1981-01-05 to 1982-02-01 (NCEI Accession 8800054)

Temperature profile data were collected using bathythermograph (BT/XBT) casts from SEAPAC BUNKER HILL and other platforms in the Pacific Ocean from January 5, 1981 to February 1, 1988. Data were submitted by US Navy; Ships of Opportunity as part of the International Decade of Ocean Exploration / North Pacific Experiment (IDOE/NORPAX) 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.
