| During France JGOFS campaign ANTARES 2 (R.V. Marion Dufresne), samples were taken along a section of the 62 degrees E meridian from 49 degrees to 66 degrees S. The high temperature catalytic oxidation (HTCO) method was used to determine the concentration of dissolved organic carbon (DOC). The analyses were conducted both on-board ship and after the cruise in the laboratory. Collecting and storing acidified samples for post-cruise analysis induced no significant differences. The use of two separate but identical channels on the carbon analyzer increased the number of samples analysed per day and allowed independent monitoring of the instrument blank and the calibration of the detector response. The mixed layer concentrations of organic carbon varied from... |

| The results of an existing one-dimensional diagnostic model that calculates the fugacity of CO2 (fCO2) in the surface layer of the southern ocean were compared with in situ observations from different ocean sectors and seasons. Our model is based on the translation of monthly variations of constraints fields into surface water fCO2 variations, and was used to assess the CO2 uptake of the southern ocean. In situ observations are useful to verify the model results and were here applied to improve the estimation of the CO2 uptake of the southern ocean south of 50°S. The model reproduces the fCO2 distribution in both Pacific and Indian sectors of the southern ocean satisfactorily, the mean deviation being only 5 matm. This discrepancy requires only a minor... |
