Ocean-atmosphere trace gas exchange

摘要: The oceans contribute significantly to the global emissions of a number atmospherically important volatile gases, notably those containing sulfur, nitrogen and halogens. Such gases play critical roles not only in biogeochemical cycling but also wide range atmospheric processes including marine aerosol formation modification, tropospheric ozone destruction, photooxidant stratospheric loss. A are greenhouse others influence Earth's radiative budget indirectly through and/or by modifying oxidant levels thus changing lifetime such as methane. In this article we review current literature concerning physical, chemical biological controls on sea-air dimethyl sulphide (DMS), halocarbons, nitrogen-containing ammonia (NH3), amines (including dimethylamine, DMA, diethylamine, DEA), alkyl nitrates (RONO2) nitrous oxide (N2O), non-methane hydrocarbons (NMHC) isoprene oxygenated (O)VOCs, methane (CH4) carbon monoxide (CO). Where possible emission budgets these well known mechanisms for their loss surface ocean.
