PACKAGE DESCRIPTION: This dataset includes chemical, discrete sample, physical and profile data collected from METEOR in the South Atlantic Ocean from 1994-03-29 to 1994-05-11 and retrieved during cruise WOCE_A08. These data include CHLOROFLUOROCARBON-11 (CFC-11), CHLOROFLUOROCARBON-113 (CFC-113), CHLOROFLUOROCARBON-12 (CFC-12), Carbon tetrachloride (CCL4), DELTA HELIUM-3, DISSOLVED INORGANIC CARBON, DISSOLVED OXYGEN, HELIUM, HYDROSTATIC PRESSURE, NEON, NITRATE + NITRITE CONTENT (CONCENTRATION), 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 Douglas Wallace of Universitat Kiel; Institut Fur Meereskunde; Forschungsbereich Marine Biogeochemie and Kenneth Johnson [affiliation unknown] as part of the WOCE_A08 data set.
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.

Detailed sampling and analyzing information: |
The TCO2 was determined using two automated dynamic headspace SOMMA sample processors with coulometric detection of the CO2 extracted from acidified samples. A description of the SOMMA-coulometry system and its calibration can be found in Johnson et al. (1987); Johnson and Wallace (1992); and Johnson et al. (1993). |
