The author determines the concentrations of N{sub 2}O, CH{sub 4}, OCS and (CH{sub 3}){sub 2}S (DMS) in surface waters of estuaries, shelf, shelf edge, open oceans using continuous equilibration techniques and automated gas chromatography, as described by Bange et al. Atmospheric concentrations of these gases are also determined in tandem. Horizontal profiles during cruise tracks have time resolution of up to one hour. Super- or under-saturation of surface sea waters for these gases is established, after computing equilibrium air-sea values using the high precision atmospheric concentration measurements and Henry law constants.
