The seasonal cycling of the climatically-active sulfur gas dimethylsulfide (DMS),its precursor dimethylsulfoniopropionate (DMSP) as well as dimethylsulfoxide (DMSO) was quantified through the 2005-2006 spring-to-fall plankton succession in waters off the Western Antarctic Peninsula.The Southern Ocean is known for its large blooms of phytoplankton species with very different biogeochemical signatures in the case of organic carbon and sulfur water column cycling.Large peaks of DMS,DMSP and DMSO occurred simultaneously with,or were followed by,maxima in algal and bacterial biomass.The 2005-2006 spring-summer growth period in this region was characterized by significantly higher carbon biomass and productivity than previous years.We compare DMS and DMSP biological,photochemical,and sea-air losses during this period.
