  abstract = {{T}he {A}tlantic and {A}rctic {O}ceans are critical components of the global carbon cycle. {H}ere we quantify the net sea-air {CO}2 flux, for the first time, across different methodologies for consistent time and space scales for the {A}tlantic and {A}rctic basins. {W}e present the long-term mean, seasonal cycle, interannual variability and trends in sea-air {CO}2 flux for the period 1990 to 2009, and assign an uncertainty to each. {W}e use regional cuts from global observations and modeling products, specifically a p{CO}(2)-based {CO}2 flux climatology, flux estimates from the inversion of oceanic and atmospheric data, and results from six ocean biogeochemical models. {A}dditionally, we use basin-wide flux estimates from surface ocean p{CO}(2) observations based on two distinct methodologies. {O}ur estimate of the contemporary sea-air flux of {CO}2 (sum of anthropogenic and natural components) by the {A}tlantic between 40 degrees {S} and 79 degrees {N} is -0.49 +/- 0.05 {P}g {C} yr(-1), and by the {A}rctic it is -0.12 +/- 0.06 {P}g {C} yr(-1), leading to a combined sea-air flux of -0.61 +/- 0.06 {P}g {C} yr(-1) for the two decades (negative reflects ocean uptake). {W}e do find broad agreement amongst methodologies with respect to the seasonal cycle in the subtropics of both hemispheres, but not elsewhere. {A}greement with respect to detailed signals of interannual variability is poor, and correlations to the {N}orth {A}tlantic {O}scillation are weaker in the {N}orth {A}tlantic and {A}rctic than in the equatorial region and southern subtropics. {L}inear trends for 1995 to 2009 indicate increased uptake and generally correspond between methodologies in the {N}orth {A}tlantic, but there is disagreement amongst methodologies in the equatorial region and southern subtropics.},
