Temperature profiles from expendable bathythermograph (XBT) casts from the USCGC RUSH in the North Pacific Ocean in support of the Integrated Global Ocean Services System (IGOSS) project from 1973-01-30 to 1973-03-09 (NCEI Accession 7300424)
XBT data were collected from the USCGC RUSH in support of the Integrated Global Ocean Services System (IGOSS) project. Data were collected by the US Coast Guard (USCG) from 30 January 1973 to 09 March 1973. Data were processed by NODC to the NODC standard Universal Bathythermograph Output (UBT) format.
The UBT file format is used for temperature-depth profile data obtained using expendable bathythermograph (XBT) instruments. Standard XBTs can obtain profiles at depths of about 450 or 760 m. With special instruments, measurements can be obtained to 1830 m. Cruise information, position, date, and time are reported for each observation. The data record comprises pairs of temperature-depth values. Unlike the MBT data file, in which temperature values are recorded at uniform 5m intervals, the XBT Data File contains temperature values at non-uniform depths. These depths are at a minimum number of points ("inflection points") required to record the temperature curve to an acceptable degree of accuracy. On output, however, the user may request temperature values either at inflection points or interpolated to uniform depth increments.

Supplemental Information | Note: Preliminary metadata for this accession were extracted from a legacy database maintained by the U.S. National Oceanographic Data Center (NODC). The design of the database did not exactly reflect the FGDC Content Standard for Digital Geospatial Metadata (CSDGM). To develop more accurate metadata, NCEI reviews metadata for all accessions on an ongoing basis. Metadata were updated in August of 2007.
