Links Between Dimethylated Sulfur and Phytoplankton Photophysiology in the Surface Ocean: Geographical Patterns and Short-Term Variability

Abstract

[EN] Dimethylsulfide (DMS) and its algal precursor, dimethylsulfopropionate (DMSP), are major players in the oceanic and atmospheric sulfur cycle. DMS is the most abundant volatile organic sulfur compound in the upper ocean and its global emission accounts for ca. 28 Tg S per year, thus representing the main natural source of sulfur to the troposphere and about 30% of the global (including anthropogenic) sulfur emissions.
