2. 1. On Biogenic Halocarbons in Antarctic Waters

   Author : Erik Mattsson; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Volatile biogenic halocarbons; Antarctica; Southern Ocean; Sea ice; Snow; Air-sea exchange;

   Abstract : Little is known regarding the distribution of naturally produced volatile halogenated organic compounds, halocarbons, in Antarctic waters and the contribution of these waters to the global atmospheric load of halogens. In the atmosphere, halocarbons are degraded by photolysis, and form reactive halogen radicals. READ MORE

4. 2. Biogenic Halocarbons in Polar Sea Ice

   Author : Anna Granfors; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Volatile biogenic halocarbons; Sea ice; Antarctica; ice-air flux; gases;

   Abstract : Sea ice is to date a rather poorly investigated part of the cycling of volatile halogenated organic compounds, halocarbons. These compounds are natural sources of reactive iodine and bromine to the atmosphere, and are produced in the marine environment. READ MORE

5. 3. Formation and Distribution of Marine Biogenic Halocarbons with Emphasis on Polar Regions

   Author : Anders Karlsson; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; volatile biogenic halocarbons; Arctic Ocean; Southern Ocean; sea ice; snow; air-sea exchange; cyanobacteria;

   Abstract : It is well-established that marine micro- and macroalgae form volatile halogenated compounds (halocarbons). Production occurs throughout the world ocean with strong regional sources in coastal areas. In the atmosphere, these compounds are converted to reactive inorganic halogen compounds, which degrade ozone. READ MORE
