Temperature profile and water depth data collected from BAINBRIDGE using BT and XBT casts in the North Pacific Ocean from 1975-07-03 to 1977-10-31 (NCEI Accession 8900230)

Temperature profile and water depth data were collected using BT and XBT casts from the BAINBRIDGE in the North Pacific Ocean and TOGA Area - Pacific Ocean. Data were collected from 03 July 1975 to 31 October 1977 by the US Navy; Fleet Numerical Oceanography Center (FNOC)

Data has been processed by NODC to the NODC standard Bathythermograph (XBT) (C116) format.

The C116/C118 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. Prior to July 1994, XBT data were routinely processed to one of these standard types. XBT data are now processed and loaded directly in to the NODC Ocean Profile Data Base (OPDB). Historic data from these two data types were loaded into the OPDB.
