Temperature profiles from XBT casts from the AMAGI MARU and other platforms from North Pacific Ocean by the Hokkaido Regional Fisheries Research Laboratory and other institutions from 1904-10-04 to 1985-12-31 (NODC Accession 9200262)

Temperature profiles were collected from XBT casts from the AMAGI MARU and other platforms from 04 October 1904 to 31 December 1985. Data were collected by the Hokkaido Regional Fisheries Research Laboratory and other institutions. Additional funding for digitizing historic data were provided by the Global Ocean Data Archaeology and Rescue (GODAR) project. Data were processed by NODC to the NODC standard Universal Bathythermograph Output (UBT) format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/bt.html.

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. Depths are selected by the originator - usually at standard horizons or some fixed interval. Standard XBTs can obtain profiles to depths of either 450 or 760 m. Special instruments permitted measurements to be obtained to 1830 m.
