The Sub Arctic Pacific Ocean near Ocean Station Papa is characterized as an iron limiting area that affects phytoplankton growth and hence the production of dimethyl sulphide. Dimethyl sulphide is believed to counteract global warming by producing or being converted into other gases or atmospheric aerosols. During the Sub Arctic Ecosystem Response to Iron Enhancement Study in the summer of2002, various sulphur containing aerosols and gases including dimethyl sulphide, sea salt, biogenic non sea salt, anthropogenic non sea salt, methane sulphonic acid, biogenic sulphur dioxide and anthropogenic sulphur dioxide were collected. The objectives were to determine: -- 1) The source of SO₂ throughout SERIES; -- 2) The source of NSS SO₄ throughout SERIES; -- 3) The preferred pathway of DMS oxidation during SERIES and -- 4) The compare results of fertilized area to an unfertilized area to evaluate whether SERIES iron fertilization affected atmospheric DMS oxidation products.
