Investigation of carbon dioxide in the central South Pacific Ocean (WOCE Sections P-16C and P-17C) during the TUNES/2 expedition of the R/V Thomas Washington, July--August, 1991. Final technical report
Description: This report summarizes the results of carbon dioxide and associated hydrographic measurements made during the oceanographic expedition, TUNES/2, aboard the R/V Thomas Washington in the central South Pacific Ocean. During the 40 day expedition, the total carbon dioxide concentration in 1000 seawater samples were determined using a coulometer system and the pCO(sub 2) in 940 seawater samples were determined using an equilibrator/gas chromatograph system. The alkalinity values in 900 water samples were computed using these measurements. In addition, 156 coulometric measurements were made for the Certified Reference Solutions (Batch No. 6) and yielded a mean value of 2303.2 +or- 1.5umol/kg. The chemical characteristics for the major water masses have been determined.
