PACKAGE DESCRIPTION: This dataset includes Surface underway, chemical, discrete sample, meteorological, physical and profile data collected from THOMAS G. THOMPSON in the Bismarck Sea, Coral Sea, Gulf of Guinea, North Atlantic Ocean, North Pacific Ocean, Solomon Sea, South Atlantic Ocean and South Pacific Ocean from 1993-10-05 to 1993-11-10. These data include BAROMETRIC PRESSURE, 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, NEON, NITRATE, NITRITE, Partial pressure (or fugacity) of carbon dioxide - atmosphere, Partial pressure (or fugacity) of carbon dioxide - water, Potential temperature (theta), SALINITY, SEA SURFACE TEMPERATURE, TOTAL ALKALINITY (TA), Tritium (Hydrogen isotope), WATER TEMPERATURE, phosphate and silicate. The instruments used to collect these data include CTD, Carbon dioxide (CO2) gas analyzer, Shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement and bottle.
These data were collected by Robert M. Key of Princeton University; Department of Geosciences; Program in Atmospheric and Ocean Sciences and Christopher Sabine of US DOC; NOAA; OAR; Pacific Marine Environmental Laboratory as part of the WOCE P10 and WOCE_P10 data set. CDIAC associated the following cruise ID(s) with this data set: 3250TN026_1 and WOCE_P10
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.

Curve fitting method: |
Samples analyzed at sea were brought to 25C in a water bath, then pumped into a water- jacketed, 100-cm3, closed titration cell with a peristaltic pump. The cell design is described in the DOE Handbook (DOE 1994). The acid titrant was made by adding concentrated HCl to a 0.5 molar NaCl solution to give a normality of approximately 0.2. The calibrated acid normality (0.195091 +/- 0.000041 μmol/kg solution) was determined immediately after the cruise by A. Dickson of SIO using the coulometric technique described by Millero et al. (1993). The titration system consisted of a personal computer, a Metrohm 665 Dosimat digital burette, an Orion 720A pH meter, and a Corning semi micro pH electrode. Using a program similar to those used by previous investigators (Bradshaw and Brewer 1988; Millero et al. 1993), the system automatically titrated the sample past the carbonic acid endpoint with electromotive force (emf) intervals of approximately 13 mV. Alkalinity samples returned to the laboratory for analysis were titrated using the same methods described for the at-sea samples. However, since accurate analytical balances were available, the cell volume was determined by careful weighing of the titration cell both empty and full of deionized water at a known temperature. |
Uncertainty: |
The overal precision of TALK measurements was +/-4 μmol/kg The mean value for CRMs titrated over this period (~35 days) was 2207.6 +/- 3.5 μmol/kg (N = 40). The mean difference between duplicate P10 samples run in the lab was 3.8 +/- 5.2 μmol/kg (N = 12), not quite as good as the samples run at sea but not significantly different from zero. The mean difference between the samples run in the laboratory and the replicates run at sea immediately after collection was 3.8 +/- 4.0 μmol/kg indicating that the storage of the samples did not affect the TALK values. |
