3-year PhD position (m/f/d): Sulfur Cycling in Wetlands and its Coupling to Iron and Carbon Sulfur cycling is a fascinating but still surprisingly understudied part of wetland biogeochemistry. In oxygen-limited environments such as peatlands, the Wadden Sea, and other wetlands, sulfate can be rapidly transformed into sulfide. Sulfide, in turn, reacts strongly with iron minerals and can promote the dissolution of Fe(III) oxides, setting off a cascade of reactions that influence both iron and car…
