Results and discussion

Any other information on results incl. tables

Results of emission rate were given in nmol/m2/h:

- Marine subtropical wetlands: 9-600

- Marine temperate wetlands: 19-720

- Freshwater subtropical wetlands: 34-220

- Freshwater temperate wetlands: 0.4-700

- Ocean average: 170-340

Percentage of total regional flux of S gases was attributable to DMS for 58 %

Applicant's summary and conclusion

Conclusions:
Dimethyl sulfide is emitted in marine water and freshwater from wetland habitats in the Florida Everglades up to 400 nmol/m2/h
