Photochemical production of carbonyl sulphide in marine surface waters
Abstract
A series of experiments in near-shore ocean and estuarine waters has been performed to investigate the oceanic source of carbonyl sulfide (COS) gas. Dissolved COS in near-surface waters is found to be supersaturated with respect to atmospheric COS, and the dissolved concentrations vary diurnally with light intensity. COS production appears to be independent of salinity, photosynthetic activity, and microbial activity, and is probably the result of photooxidation of organic matter.
