Carbonyl sulfide (COS), dimethyl sulfide (DMS), and carbon disulfide (CS 2 ) concentrations were determined in seawater and the overlying atmosphere of the Changjiang Estuary and the adjacent area during two cruises from 22 February 2016 to 15 March 2016 and from 03 July 2016 to 25 July 2016. The concentration ranges of COS, DMS, and CS 2 in seawater during winter were 121–388 pmol L −1 , 0.321–1.59 nmol L −1 , and 10.3–46.8 p...
