These data include ALKALINITY, CHLOROFLUOROCARBON-11 (CFC-11), CHLOROFLUOROCARBON-12 (CFC-12), DELTA CARBON-13, DELTA CARBON-14, DELTA HELIUM-3, DISSOLVED INORGANIC CARBON, DISSOLVED OXYGEN, HELIUM, HYDROSTATIC PRESSURE, NITRATE, NITRITE, PHOSPHATE, Partial pressure (or fugacity) of carbon dioxide, Potential temperature (theta), SALINITY, SILICATE, Tritium (Hydrogen isotope) and WATER TEMPERATURE. The instruments used to collect these data include CTD and bottle. These data were collected by Taro Takahashi of Lamont-Doherty Earth Observatory (LDEO) as part of the WOCE_P16S17S 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:0115171 Preview graphic PNG 0115171 NCEI ACCESSION NUMBER 2013-12-19 publication CHLOROFLUOROCARBON-11 (CFC-11) CHLOROFLUOROCARBON-12 (CFC-12) DELTA CARBON-13 DELTA CARBON-14 DELTA HELIUM-3 DISSOLVED INORGANIC CARBON (DIC) DISSOLVED OXYGEN HELIUM HYDROSTATIC PRESSURE NITRATE NITRITE partial pressure of carbon dioxide - water 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 USNS Thomas Washington platform NODC PLATFORM NAMES THESAURUS Lamont-Doherty Earth Observatory 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 South Pacific Ocean place NODC SEA AREA NAMES THESAURUS oceanography theme WMO_CategoryCode 2012-09-15 publication COLUMBIA/LDEO > Lamont-Doherty Earth Observatory, Columbia University 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.

(1985). This system consists of a coulometer (Model 5011) manufactured by the UIC Inc. (Jollies, IL) and a sample introduction/CO2 extraction system of the LDEO design, which differs from the Single Operator Multiparameter Metabolic Analyzer (SOMMA) system used by most of the other participants of the DOE/CO2 program. In the LDEO system (Chipman et al., 1993), a precisely known volume of seawater sample is introduced manually into an CO2 extraction vessel using a calibrated syringe, instead of an automated pipette used by the SOMMA system.; CRM batch number: 6 Parameter or Variable: Total alkalinity; Abbreviation: TA; Observation type: discrete; In-situ / Manipulation / Response variable: in-situ observation; Measured or calculated: Measured; Type of titration: potentiometric; Cell type (open or closed): Closed; Curve fitting method: The TALK concentration in 139 samples was determined on shore at the laboratory of C.
