    • Physical, chemical, and other data from bottle and XBT casts from the DIAMOND SHOALS and other platforms as part of the Outer Continental Shelf - South Atlantic project from 1958-01-01 to 1975-10-18 (NCEI Accession 7700635)

    Metadata Updated: March 17, 2023

    Physical, chemical, and other data from CTD and XBT casts from the DIAMOND SHOALS and other platforms. Data were collected by the United States Coast Guard and other institutions as part of the Outer Continental Shelf - South Atlantic project from 01 January 1958 to 18 October 1975. Data were processed by NODC to the NODC standard Station Data II Output Format (SD2) and the Universal Bathythermograph Output Format (UBT).

    The SD2 file format is used for physical-chemical oceanographic data recorded at discrete depth levels. Most of the observations were made using multi-bottle Nansen casts or other types of water samplers. A small amount (about 5%), were obtained using electronic CTD (conductivity-temperature-depth) or STD (salinity-temperature-depth) recorders. The CTD/STD data were reported to NODC at depth levels equivalent to Nansen cast data, however, and have been processed and stored the same as the Nansen data. Cruise information, position, date and time are reported for each station. Each station contains the measurements taken at observed depth levels, but also includes data values interpolated to a set of standard depth levels.

    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. The XBT data files contain temperature values at originators defined depths. Standard XBTs can obtain profiles to depths of either 450 or 760 m. Special instruments permit measurements to be obtained to 1830 m.

    Data has been processed by NODC to the NODC standard Current Meter (Components) (F015) format.

    The F015 format is used for time series measurements of ocean currents. These data are obtained from current meter moorings and represent Eulerian method of current measurement, i.e., the meters are deployed at a fixed point and measure flow past a sensor. Position, bottom depth, sensor depth, and meter characteristics are reported for each station. The data record comprises values of east-west (u) and north-south (v) current vector components at specified date and time. Current direction is defined as the direction toward which the water is flowing with positive directions east and north and negative directions west and south. Data values may be subject to averaging or filtering and are typically reported at 10-15 minute time intervals. Water temperature, pressure, and conductivity or salinity may also be reported. A text record is available for optional comments.
