Oceanographic station data from bottle casts from Ocean Weather Station A (OWS-A) in the North Atlantic Ocean from the from 1964-01-12 to 1966-06-27 (NCEI Accession 7300616)
Oceanographic station data were collected within a 1-mile radius of Ocean Weather Station A (6200N 03300W) and in transit. Data were collected by the Hydrographic Office, Ministry of Defence from 12 January 1964 to 27 June 1966. Data were processed by NODC to the NODC standard Station Data II Output Format (SD2).
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.

Supplemental Information | Note: Preliminary metadata for this accession were extracted from a legacy database maintained by the U.S. National Oceanographic Data Center (NODC). The design of the database did not exactly reflect the FGDC Content Standard for Digital Geospatial Metadata (CSDGM). To develop more accurate metadata, NCEI reviews metadata for all accessions on an ongoing basis. Metadata were updated in July of 2007.
