Central Arctic Ocean surface–atmosphere exchange of CO<sub>2</sub> and CH<sub>4</sub> constrained by direct measurements

Abstract CH 4 CO 2 CO 2 CH 4 CH 4 CO 2 CO 2 ∘  N from the Synoptic Arctic Survey (SAS) expedition carried out on the Swedish icebreaker Oden CH 4 CO 2 cm h - 1 applicable over the observed 10 m wind speed range (1–11 m s - 1). The average observed air–sea CO 2 - mmol m - 2 d - 1, and the average air–snow CO 2 - mmol m - 2 d - 1. Extrapolating these fluxes and the corresponding sea-ice concentrations gives an August and September flux for the CAO of - mmol m - 2 d - 1, within the range of previous indirect estimates. CH 4 µ mol m - 2 d - 1, accounting for sea-ice concentration, equates to an August and September CAO flux of 0.35 µ mol m - 2 d - 1, lower than previous estimates and implying that the CAO is a very small (≪ CH 4 to the atmosphere.
