Physical and other data from bottle and XBT casts from the AGS NO 2 and other platforms from the NW Pacific (limit-180) from 1967-01-07 to 1984-03-02 (NCEI Accession 8500196)

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.
