Temporal variability of the anthropogenic CO2 storage in the Irminger Sea
11 pages, 4 figures. The anthropogenic CO2 (C-ant) estimates from cruises spanning more than two decades (1981–2006) in the Irminger Sea area of the North Atlantic Subpolar Gyre reveal a large variability in the C-ant storage rates. During the early 1990’s, the C-ant storage rates (2.3 ± 0.6 mol C m...

During the early 1990’s, the C-ant storage rates (2.3 ± 0.6 mol C m−2 yr−1) doubled the average rate for 1981–2006 (1.1 ± 0.1 mol C m−2 yr−1), whilst a remarkable drop to almost half that average followed from 1997 onwards.
