Bathythermograph and other data from CLYDE-OWS A, HECLA and other platforms from 1949-06-10 to 1976-10-15 (NCEI Accession 7601931)

This dataset consists of British bathythermograph data collected between 1949 and 1976. The data have been digitized and processed by NODC to the NODC Bathythermograph XBT (C116) and NODC Mechanical Bathythermograph (MBT/C128) formats. The data type C116 contained 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. 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. The C128 format is used for temperature-depth profile data obtained using the mechanical bathythermograph (MBT) instrument. The maximum depth of MBT observations is approximately 285 m. Therefore, MBT data are useful only in studying the thermal structure of the upper layers of the ocean. Cruise information, date, position, and time are reported for each observation. The data record comprises pairs of temperature-depth values. Temperature data in this file are recorded at uniform 5 m depth intervals.
