Temporal variability of the anthropogenic CO 2 storage in the Irminger Sea
International audience The anthropogenic CO 2 (C ant ) estimates from cruises spanning more than two decades (1981–2006) in the Irminger Sea area reveal a large variability of the C ant storage rates in the North Atlantic Subpolar Gyre. During the early 1990's, the C ant uptake rates doubled th...

International audience The anthropogenic CO 2 (C ant ) estimates from cruises spanning more than two decades (1981–2006) in the Irminger Sea area reveal a large variability of the C ant storage rates in the North Atlantic Subpolar Gyre. During the early 1990's, the C ant uptake rates doubled the average rate for 1981–2006, whilst a remarkable drop to almost half that average followed from 1997 onwards. The C ant storage evolution runs parallel to CFC12 inventories and is in good agreement with C ant uptake rates of increase calculated from sea surface pCO 2 measurements. The North Atlantic Oscillation shift from a positive to a negative phase in 1996 led to a reduction of the air-sea heat loss in the Labrador Sea.
