These data include dissolved inorganic carbon (DIC), alkalinity, temperature, salinity, nutrients, chlorofluorocarbons (CFCs), delta C14 and C14Error. These data were collected by Alain Poisson of Universite Pierre et Marie Curie; Laboratoire de Biogeochimie et Chimie Marines (LBCM) as part of the WOCE_I06S 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:0115015 Preview graphic PNG 0115015 NCEI ACCESSION NUMBER 2013-12-12 publication CHLOROFLUOROCARBON-11 (CFC-11) CHLOROFLUOROCARBON-12 (CFC-12) DELTA CARBON-14 DISSOLVED INORGANIC CARBON (DIC) DISSOLVED OXYGEN HYDROSTATIC PRESSURE NITRATE phosphate Potential temperature (theta) SALINITY silicate total alkalinity WATER TEMPERATURE theme NODC DATA TYPES THESAURUS bottle CTD instrument NODC INSTRUMENT TYPES THESAURUS chemical discrete sample physical profile theme NODC OBSERVATION TYPES THESAURUS MARION DUFRESNE platform NODC PLATFORM NAMES THESAURUS Université Pierre et Marie Curie, Laboratoire de Biogeochimie et Chimie Marines 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 Indian 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.

Sal=33.420 TCO2=1988.78 TALK=2201.88 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: Single point titration; Curve fitting method: A potentiometric titration derived from the method developped by Edmond (1970) was used to estimate Total Inorganic Carbon (TCO2 p) and Total Alkalinity (TA p). The titration system was composed of a Radiometer ABU 80 burette, a Radiometer PHM80 pH meter and a PC/AT Tandon micro-computer to drive the burette and record the data.; Uncertainty: To test the precision of the method, replicate samples were taken at all the stations. Another way to estimate the precision of the measurements is to calculate the regression curve of TCO2 versus potential temperature in deep water. the calculation was made on the 460 samples whose temperature is between -0.8C and 0.4C; 14 data of TALK and 22 of TCO2 were rejected because very far from the regression curve. This is possibly due to bad samplings or any problem during the titration. The standard deviation was 2.4 ueq/kg for TALK and 3.7 μmol/kg for TCO2. Based on replicate samples accuracy was 0.9 (+/-0.8) μmol/kg for TALK (40 samples).; Method reference: Edmond J.
