Temperature profile and other data collected using CTD, BT, and XBT casts from the NOAA Ship RESEARCHER and other platforms in the North/South Pacific Ocean and North/South Atlantic Ocean from 13 January 1973 to 14 March 1983 (NCEI Accession 8300091)

Metadata Updated: March 10, 2021

Temperature profile and other data were collected using CTD, BT, and XBT casts from the NOAA Ship RESEARCHER and other platforms in the North/South Pacific Ocean and North/South Atlantic Ocean. Data were collected from 13 January 1973 to 14 March 1983. Data were collected by the Atlantic Oceanographic and Meteorological Laboratory in Miami, Florida and other institutes with support from the Equatorial Pacific Ocean Climate Studies (EPOCS) project. Data were processed by NODC to the NODC standard Universal Bathythermograph Output (UBT) format and High-Resolution STD/CTD Data (F022) format. Full format description is available from NODC at http://www.nodc.noaa.gov/General/NODC-datafmts.html

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.
