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...
