Partial pressure (or fugacity) of carbon dioxide, dissolved inorganic carbon, alkalinity, temperature, salinity and other variables collected from discrete sample and profile observations using CTD, Coulometer for DIC measurement and other instruments from KNORR in the North Atlantic Ocean, South Atlantic Ocean and Southern Oceans from 1983-10-07 to 1984-02-19 (NCEI Accession 0117503)
PACKAGE DESCRIPTION: This dataset includes chemical, discrete sample, physical and profile data collected from KNORR in the North Atlantic Ocean, South Atlantic Ocean and Southern Oceans (> 60 degrees South) from 1983-10-07 to 1984-02-19. These data include CHLOROFLUOROCARBON-11 (CFC-11), CHLOROFLUOROCARBON-12 (CFC-12), DISSOLVED INORGANIC CARBON (DIC), DISSOLVED OXYGEN, HYDROSTATIC PRESSURE, NITRATE, NITRITE, Partial pressure (or fugacity) of carbon dioxide - water, Potential temperature (theta), RADIUM ISOTOPES, SALINITY, TOTAL ALKALINITY (TA), WATER TEMPERATURE, phosphate and silicate. The instruments used to collect these data include CTD, Coulometer for DIC measurement, Flask with closed headspace for discrete carbon dioxide (CO2) measurement and bottle. These data were collected by Taro Takahashi of Columbia University; Lamont-Doherty Earth Observatory as part of the AJAX_1983 Expedition data set. CDIAC associated the following cruise ID(s) with this data set: AJAX_1983 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.
