CTD data from ISLAS ORCADAS in the SE Atlantic from 1977-01-05 to 1977-02-16 (NCEI Accession 8100431)
CTD from ISLAS ORCADAS (cruise 12) From SE Atlantic (limit-20 W) from January 5, 1977 to February 16, 1977. The data was collected by Secretaria de Marina, Servicio de Hidrografia Naval, Buenos Aires, Argentina. Data was submitted by Sarah Rennie. The originators data submitted on tapes has been converted into current NODC data storage format. C100 Ocean Station Data has been processed by NODC.
The Oceanographic Station Data (C100) 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 and 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 | The publication listed below is related to the data collection and is available from the NOAA Central Library: Islas Orcadas cruise 12, Jan.-Feb. 1977 : hydrographic stations 53-12. Palisades, N.Y. : Lamont-Doherty Geological Observatory of Columbia University, 1981. Note: 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). Principal Investigator (PI) and organization contact information accurately represents all available information from the legacy database at the time that this description was created. However, proper attribution of a PI to a specific institution or the role (submitting or collecting) taken by an institution may not be correct due to inexact mapping between fields in the legacy database and the CSDGM. Due to this uncertainty, the contact information was initially recorded in the Supplemental Information element of the CSDGM description. To develop more accurate metadata, NCEI reviews metadata for all accessions on an ongoing basis.
