The distribution of dissolved CH4 in the Southern Ocean at 140 E was measured during the austral summer. Surface CH4 was supersaturated on average, and the calculated mean sea-air flux rate was 0.32 μmolm−2 d−1. The vertical distributions exhibited a CH4 5 maximum at approximately 125 m (ÉCH4, 2.94...
