Register for the 7th DMS(P) Symposium: Sulfur Carbon Nexus in the SOLAS Sphere

A joint workshop with SCOR, SOLAS, and Schmidt Sciences: Climate October 12-15, 2026 in person at Bigelow Laboratory (Boothbay Harbor, Maine) and online. The organosulfur compound dimethylsulfoniopropionate (DMSP) ignited an entire subfield of biogeochemistry to investigate the precursor of the “anti-greenhouse gas” dimethylsulfide (DMS). Since then, decades of research have unveiled the importance of DMS(P),
