Dimethylsulphide production in the Southern Ocean using a Nitrogen Based Flow network Model and Field Measurements from ACE-1
Dimethylsulphide (DMS) has been implicated in climate change as a possible negative feedback to global warming, and several Models have been developed that simulate the production of DMS in the marine environment. The focus of this study is to improve the nitrogen based Gabric Model, using field dat...
