This data file contains trace chemicals reported in a format similar to SD2. These data were collected by Scripps Institute of Oceanography (SIO) from July 12, 1972 to April 24, 1978 in the Atlantic, Pacific and Indian Oceans as part of the International Decade of Ocean Exploration / Geochemical Ocean Section Study (IDOE/GEOSECS) Program. The data parameters measured were: barium, total organic carbon, deuterium, radium-226, lead-210, polonium, tritium, helium, neon, strontium-90, and cesium-137.

Chemical, physical, and other data were collected from bottle and CTD casts in the Indian from the MELVILLE from 04 December 1977 to 24 April 1978. Data were collected by the Scripps Institution of Oceanography (SIO) as part of the International Decade of Ocean Exploration / Geochemical Ocean Study (IDOE/GEOSECS). Physical parameters include depth, temperature, salinity, pH, and pressure. Chemical parameters include concentrations of carbon dioxide, oxygen, phosphate, nitrate, nitrite, and silicate. Analog data are available for this accession by contacting NODC user services.

Temperature and salinity profile data were collected using STD/CTD casts from KNORR in a world-wide distribution from July 24, 1972 to June 9, 1974. Data were submitted by Scripps Institution of Oceanography as part of the International Decade of Ocean Exploration / Geochemical Ocean Section Study (IDOE/GEOSECS) project. Data were processed by NODC to the NODC standard High-Resolution STD/CTD Data (F022) format. The F022 format contains high-resolution data collected using CTD (conductivity-temperature-depth) and STD (salinity-temperature-depth) instruments. As they are lowered and raised in the oceans, these electronic devices provide nearly continuous profiles of temperature, salinity, and other parameters. Data values may be subject to averaging or filtering or obtained by interpolation and may be reported at depth intervals as fine as 1m. Cruise and instrument information, position, date, time and sampling interval are reported for each station. Environmental data at the time of the cast (meteorological and sea surface conditions) may also be reported. The data record comprises values of temperature, salinity or conductivity, density (computed sigma-t), and possibly dissolved oxygen or transmissivity at specified depth or pressure levels. Data may be reported at either equally or unequally spaced depth or pressure intervals. A text record is available for comments.

Oceanographic profiles of physical, biological, and chemical variables were acquired during numerous cruises in seas world-wide since 1877. The data were submitted to the International Council for the Exploration of the Sea (ICES). The recent measurements were made using CTD and bottle. Most of the data are in ICES Oceanographic Format.

Physical, nutrients, and chemical data were collected using bottle, CTD, XBT, XSV, AXBT, thermometer, and tide gauge casts from AIRCRAFT in the North and South Pacific Ocean. Data were collected and submitted by the Naval Oceanographic Office. Data were collected from 26 June 1925 to 28 April 1996.

Physical, chemical, biological, meteorological, and other data were collected from bottle casts, CTD casts, and divers from FIXED PLATFORMS. Data were collected by Western Washington University (WWU) from 06 February 1989 to 12 March 1998. Physical parameters include water temperature, pH, dissolved oxygen, turbidity, and salinity. Nutrients parameters include concentrations of ammonia, nitrate, phosphate, phaeopigment, and C02. Meteorological parameters include wind speed, rainfall, and cloud cover. Skin diver data include sighting of juvenile rockfish, collection of sea cucumbers, and collection of green urchins.

Phytoplankton, chemical, physical, and other data were collected using bottle, current meter, net, pump, and CTD casts in the North Sea from April 15, 1988 to July 30, 1991. Data were submitted by British Oceanographic Data Center; Proudman Oceanographic Laboratory as part of the North Sea Project.

This dataset includes discrete sample and profile data collected during the R/V Knorr KN199-04, GEOTRACES-2010 cruise (EXPOCODE 316N20101015) in the North Atlantic Ocean from 2010-10-15 to 2010-11-05. These data include CTD temperature, salinity, oxygen and nutrients. The instruments used to collect these data include CTD, Niskin bottles and spectrophotometer.
