Trends in North Atlantic sea-surface f CO 2 from 1990 to 2006
International audience We examine observations from 1990 to 2006 from four voluntary observing ships and two time-series stations in the North Atlantic, fitting a sinusoidal annual cycle and linear year-on-year trend at all locations where there are sufficient data. Results show that in the subtropi...

International audience We examine observations from 1990 to 2006 from four voluntary observing ships and two time-series stations in the North Atlantic, fitting a sinusoidal annual cycle and linear year-on-year trend at all locations where there are sufficient data. Results show that in the subtropical regions, sea-surface f CO 2 has closely followed the increasing trend in atmospheric f CO 2 . In contrast, farther north, sea-surface f CO 2 has increased faster than f CO 2 in the atmosphere. The resulting Δ f CO 2 , driving air–sea flux of CO 2 , has therefore decreased in the North Atlantic, particularly at higher latitudes, as has the annual mean air–sea flux. Several underlying causes may have led to the observed changes in sea-surface f CO 2 . Low-frequency modes, such as the North Atlantic Oscillation, lead to changes in the sea-surface temperature, in sea-surface circulation and in vertical mixing, affecting sea-surface f CO 2 through biogeochemical processes.
