| 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... |

| Sections from two ''Polar-stern'' cruises in austral winter 1992 and summer 1992/1993 were used to track the course of Circumpolar Deep Water (CDW) in the Weddell Sea. Total inorganic carbon (TCO2) is a valuable tracer for that water mass because it permits identification of features that cannot be seen in the distributions of temperature and salinity. Upon entrance into the eastern Weddell Gyre, a shallow maximum in TCO2 at about 200 m (together with a temperature maximum and oxygen minimum) indicates the depth level to which vertical mixing with Winter Water penetrates the CDW layer in the Weddell Gyre. The lower boundary of this CDW layer, which is not apparent in the temperature and salinity profiles, is a TCO2 maximum at 1000-1500 m (sigma(theta)... |
