| Zusammenfassung |
| Five of the most recent observational methods to estimate anthropogenic
CO2 (Cant) are applied to a high-quality dataset from five
representative sections of the Atlantic Ocean extending from the Arctic to
the Antarctic. Between latitudes 60° N–40° S all methods give similar
spatial distributions and magnitude of Cant. However, discrepancies are
found in some regions, in particular in the Southern Ocean and Nordic Seas.
The differences in the Southern Ocean have a significant impact on the
anthropogenic carbon inventories. The calculated total inventories of
Cant for the Atlantic referred to 1994 vary from 48 to 67 Pg (1015 g) of carbon,
with an average of 54±8 Pg C, which is higher than
previous estimates. These results, both the detailed Cant distributions
and extrapolated inventories, will help to evaluate biogeochemical ocean
models and coupled climate-carbon models. |
