Temperature and salinity profiles from expendable bathythermograph (XBT) and CTD casts from NOAA Ship MILLER FREEMAN and other Platforms from Coastal Waters of Washington/Oregon and other locations in support of the Integrated Global Ocean Services System (IGOSS) from 1977-07-12 to 1983-07-26 (NCEI Accession 8300102)
XBT and CTD data were collected from NOAA Ship MILLER FREEMAN and other Platforms in support of the Integrated Global Ocean Services System (IGOSS) project. Data were collected by the US DOC; NOAA; National Ocean Service - Silver Spring (NOS) and other institutions from 12 July 1977 to 26 July 1983. Data were processed by NODC to the NODC standard Universal Bathythermograph Output (UBT) and the F022 CTD formats.
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.
The F022 format contains high-resolution data collected using CTD (conductivity-temperature-depth) and STD (salinity-temperature-depth) instruments. As they are lowered and raised in the oceans, these electronic devices provide nearly continuous profiles of temperature, salinity, and other parameters. Data values may be subject to averaging or filtering or obtained by interpolation and may be reported at depth intervals as fine as 1m. Cruise and instrument information, position, date, time and sampling interval are reported for each station. Environmental data at the time of the cast (meteorological and sea surface conditions) may also be reported. The data record comprises values of temperature, salinity or conductivity, density (computed sigma-t), and possibly dissolved oxygen or transmissivity at specified depth or pressure levels. Data may be reported at either equally or unequally spaced depth or pressure intervals. A text record is available for comments.

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.
