We demonstrate direct eddy covariance (EC) observations of methane (CH<sub>4</sub>) fluxes between the sea and atmosphere from an icebreaker in the eastern Arctic Ocean. EC-derived CH<sub>4</sub> emissions averaged 4.58, 1.74, and 0.14 mg m<sup>-2</sup> day<sup>-1</sup> in the Laptev, East Siberian, and Chukchi seas, respectively, corresponding to annual sea-wide fluxes of 0.83, 0.62, and 0.03 Tg year<sup>-1</sup>. These EC results answer concerns that previous diffusive emission estimates, whic ...[more]
