| The Southern Ocean is thought to play an important role in the context of global warming and anthropogenic emissions of CO(2) due to its high sensitivity to both climate change and changes in the carbon cycle. Assessing the penetration of anthropogenic CO(2) (C(ant)) into the Southern Ocean is therefore highly relevant to reduce the uncertainties attached to both the present knowledge of anthropogenic carbon inventories and predictions made by current ocean carbon models. This study compares different data-based approaches for estimating the distribution of C(ant) in the ocean: a recently developed method based on the composite Tracer Combining Oxygen, Inorganic Carbon, and Total Alkalinity (TrOCA) and the "historical'' back-calculation methods (the... |

| Chlorofluorocarbon (CFC) 11 and 12 transports across the transoceanic World Ocean Circulation Experiment (WOCE) A25 section in the subpolar North Atlantic are derived from an inverse model using hydrographic and ADCP data (Lherminier et al., 2007). CFC and anthropogenic carbon (C-ANT) advective transports contrary to expected are uncoupled: C-ANT is transported northeastwards (82 +/- 39 kmol s(-1)) mainly within the overturning circulation, while CFC-11 and CFC-12 are transported southwestwards (-24 +/- 4 and -11 +/- 2 mol s(-1), respectively) as part of the large-scale horizontal circulation. The main reason for this uncoupled behaviour is the complex CFC vs. C-ANT relation in the ocean, which stems from the contrasting temperature relation for both... |
