We invite interested scientists to submit an abstract to 2015 Goldschmidt session 7d entitled “Sulfur Cycling in Ecosystems: Insights at Pore-Scale to Landscape Scale”. This session will feature Dr. Anna Szynkiewicz (University of Tennessee) as keynote speaker. The abstract submission deadline is April 2, 2015 (see: http://goldschmidt.info/2015)
Sulfur Cycling in Ecosystems: Insights at Pore-Scale to Landscape Scale
Keynote: Anna Szynkiewicz (University of Tennessee)
Physical, chemical, isotopic and modeling approaches are capable of providing novel and unique information about sources, processes, pools and reaction rates controlling sulfur cycling in ecosystems on our continents. Recent analytical advances have enabled chemical and isotopic analyses on unprecedented spatial and temporal scales for gaseous, dissolved and solid sulfur species in ecosystems, and sulfur cycling models have been significantly improved. This has yielded new insights into sulfur cycling between the atmosphere, ecosphere, hydrosphere and lithosphere, addressing issues such as the role of atmospheric sulfate aerosols affecting global climate, sulfur as a nutrient, acidification reversals in watersheds, and redox reactions in waterlogged environments, among many others. These advances have also improved our understanding how the sulfur cycle is linked with the carbon, nitrogen and other element cycles in ecosystems. We invite contributions that describe advances of the current knowledge of sulfur cycling in terrestrial and aquatic ecosystems ranging from the pore-scale to landscape scales.
