Chemical, meteorological and other data from bottle casts and other instruments from the ARGOS, Arni Fridriksson and other platforms in the Barents Sea, North Sea and other locations from 1969-04-21 to 1979-07-12 (NCEI Accession 8100436)

This accession contains oceanographic data collected from bottle casts and other instruments. Data were collected from the ARGOS, Arni Fridriksson and other platforms in the Barents Sea, North Sea and other locations. Data are in the Oceanographic Station Data (SD2) format which includes meteorological, chemical and physical parameters. Data were collected from 1969-04-21 to 1979-07-12.

The SD2 format contains 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 percent) 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 (e.g., ship, country, institution), position, date, and time, and reported for each station. The principal measured parameters are temperature and salinity, but dissolved oxygen, phosphate, total phosphorus, silicate, nitrate, nitrite, and pH may be reported. Meteorological conditions at the time of the cast (e.g., air temperature and pressure, wind, waves) may also be reported, as well as auxiliary data such as water color (Forel-Ule scale), water transparency (Secchi disk depth), and depth to bottom. Values of density (sigma-t) sound velocity, and dynamic depth anomaly are computed from measured parameters. Each station contains the measurements taken at the observed depth levels, but also includes data values interpolated to a set of standard depth levels.
