Physical, chemical, and other data from bottle, XBT, and CTD casts from SHOYO and other platforms from North Pacific Ocean and other locations from 1983-11-01 to 1987-12-31 (NCEI Accession 8800147)

Physical, chemical, and other data from bottle, XBT, and CTD casts from the SHOYO and other platforms from North Pacific Ocean and other locations. Data were collected by the Maritime Safety Agency; Hydrographic Division (MSA) and other institutions from 01 November 1983 to 31 December 1987. Data were processed by NODC to the NODC standard Station Data II Output Format (SD2) and the Universal Bathythermograph Output Format (UBT). Full format descriptions are available from NODC at www.nodc.noaa.gov/.

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.
