Abstract:
Data on the N2O contents of marine sea water from the Northeast Atlantic Ocean are presented. The N2O content of marine air is rather constant. The data are in accordance with earlier measurements. The sea water down to depth greater tha 1000 meters is considerably aupersaturated with N2O with respect to air. Supersaturation values obtain from surface water allow the conclusion that part of the North Atlantic acts as a net cource of atmospheric N2O.
