Direct measurements of emission rates of some atmospheric biogenic sulfur compounds.

Abstract

Direct measurements of H2S + COS and (CH3)2S emission rates were made in two salt marshes on the coast of North Carolina during the summer of 1977. Flux measurements were made over salt marsh grass (Spartina alterniflora) and mud flats. The predominant gaseous sulfur species being emitted over the Spartina zone is (CH3)2S (average flux is ca. 0.66 g S/m2/yr), and the predominant species over the mud flat zone is H2S + COS (average flux is ca. 0.2 g S/m2/yr). - from Authors
