These data include ALKALINITY, CHLOROFLUOROCARBON-11 (CFC-11), CHLOROFLUOROCARBON-12 (CFC-12), DELTA CARBON-14, DELTA HELIUM-3, DISSOLVED INORGANIC CARBON, DISSOLVED OXYGEN, HELIUM, HYDROSTATIC PRESSURE, NEON, NITRATE, NITRITE, PHOSPHATE, Potential temperature (theta), SALINITY, SILICATE, Tritium (Hydrogen isotope), WATER TEMPERATURE and pH. The instruments used to collect these data include CTD and bottle. These data were collected by Christopher D. Winn of Hawaii Pacific University (HPU), Frank J. Millero of Rosenstiel School of Marine and Atmospheric Science (RSMAS), and Catherine Goyet of University of Perpignan Via Domita (UPVD) as part of the WOCE_P21 dataset. The World Ocean Circulation Experiment (WOCE) was a major component of the World Climate Research Program with the overall goal of better understanding the ocean's role in climate and climatic changes resulting from both natural and anthropogenic causes. The CO2 survey took advantage of the sampling opportunities provided by the WOCE Hydrographic Program (WHP) cruises during this period between 1990 and 1998. The final collection covers approximately 23,000 stations from 94 WOCE cruises. This dataset is available to the public for a wide variety of uses including scientific research and analysis. completed historicalArchive NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact HTTPS NCEI Contact Information Information for contacts at NCEI. information pointOfContact asNeeded https://www.ncei.noaa.gov/access/metadata/landing-page/bin/gfx?id=gov.noaa.nodc:0115761 Preview graphic PNG 0115761 NCEI ACCESSION NUMBER 2014-01-15 publication CHLOROFLUOROCARBON-11 (CFC-11) CHLOROFLUOROCARBON-12 (CFC-12) DELTA CARBON-14 DELTA HELIUM-3 DISSOLVED INORGANIC CARBON (DIC) DISSOLVED OXYGEN HELIUM HYDROSTATIC PRESSURE NEON NITRATE NITRITE pH phosphate Potential temperature (theta) SALINITY silicate total alkalinity Tritium (Hydrogen isotope) WATER TEMPERATURE theme NODC DATA TYPES THESAURUS bottle CTD instrument NODC INSTRUMENT TYPES THESAURUS chemical discrete sample physical profile theme NODC OBSERVATION TYPES THESAURUS R/V Melville platform NODC PLATFORM NAMES THESAURUS Hawaii Pacific University University of Miami Rosenstiel School of Marine and Atmospheric Science University of Perpignan via Domitia, Institute of Modeling and Analysis of Geo-Environment and Health dataCentre NODC COLLECTING INSTITUTION NAMES THESAURUS Carbon Dioxide Information Analysis Center dataCentre NODC SUBMITTING INSTITUTION NAMES THESAURUS World Ocean Circulation Experiment (WOCE) project NODC PROJECT NAMES THESAURUS Coral Sea South Pacific Ocean place NODC SEA AREA NAMES THESAURUS oceanography theme WMO_CategoryCode 2012-09-15 publication DOC/NOAA/NESDIS/NODC > National Oceanographic Data Center, NESDIS, NOAA, U.S. Department of Commerce DOE/ORNL/ESD/CDIAC > Carbon Dioxide Information Analysis Center, Environmental Sciences Division, Oak Ridge National Laboratory, U.
