SULFUR: THE PLANKTON/CLIMATE CONNECTION.

- Abstract
A key process in the global sulphur cycle is the transfer of volatile forms of the element from sea to land via the atmosphere. Early budgets calculated the amount of sulfur required to balance the cycle and generally assumed that this flux was achieved by formation of hydrogen sulfide in coastal waters, mud flats, etc. However, researchers made the first field measurements of dimethylsulfide (DMS) in seawater and suggested that it represented the missing link in the sulphur cycle. On the basis of present knowledge, it is thought that DMS in surface seawater arises from a network of product ion, transformation, and utilization processes. The precursor of DMS in seawater is the tertiary sulfonium compound dimethylsulfoniopropionate, which was originally identified in several species of marine macroalgae and phytoplankton.
