Biogeographic traits of dimethyl sulfide and dimethylsulfoniopropionate cycling in polar oceans
BACKGROUND: Dimethyl sulfide (DMS) is the dominant volatile organic sulfur in global oceans. The predominant source of oceanic DMS is the cleavage of dimethylsulfoniopropionate (DMSP), which can be produced by marine bacteria and phytoplankton. Polar oceans, which represent about one fifth of Earth’...
