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(-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. The C-ant storage evolution runs parallel to chlorofluorocarbon-12 inventories and is in good agreement with C-ant uptake rates of increase calculated from sea surface pCO(2) measurements. The contribution of the Labrador Seawater to the total inventory of C-ant in the Irminger basin dropped from 66% in the early... |
