Bathythermograph (XBT) data from NOAA Ship David Starr Jordan, NOAA Ship John N. Cobb, and others in the Bering Sea, Coastal Waters of Southeast Alaska and British Columbia, and others from 1975-03-29 to 1983-05-22 (NCEI Accession 8300068)

This dataset includes bathythermograph (XBT) data from NOAA Ship David Starr Jordan, NOAA Ship John N. Cobb, NOAA Ship Miller Freeman, NOAA Ship Rainier, NOAA Ship Surveyor, NORE-DICK, OCEAN LEADER, PACIFIC HARVESTER, PAT SAN MARIE, and USS PRESTIGE in the Bering Sea, Coastal Waters of Southeast Alaska and British Columbia, Gulf of Alaska, and North Pacific Ocean from 1975-03-29 to 1983-05-22. 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.
