First simulations and evaluation of decadal variability of air-sea CO2 fluxes in the North Atlantic

NOCES has been the first to make simulations in ocean carbon-cycle models 'forced' by atmospheric reanalysis data (heat and water fluxes, winds and sea ice) over a long enough period (1948-2001) to begin to start studying variability with periods of significantly more than 10 years (decadal) [Rodgers et al. 2004; Wetzel et al., 2005; Raynaud et al., 2005]. Prior to NOCES, such "forced" simulations have been made in only two different ocean carbon cycle models, and those were made for at most twenty years (1979-1999). With the longer simulations proposed here, NOCES has been able to study the effect of shifts in climate on the carbon cycle, in particular that which occurred in the mid- to late-1970s, which was the largest decadal shift in the last 50 years [Rodgers et al., 2004]. NOCES has used advanced statistical methods to distinguish decadal modes of variability from inter-annual modes and noise [Raynaud et al, 2005].
