CT11A:
Production and cycling of organosulfur and volatile organic carbon compounds: where is the field now and how do we move forward? I

Session ID#: 92759

Session Description:
In 1987, the CLAW hypothesis recognized the potential for volatile sulfur produced by phytoplankton in the surface ocean to impact the Earth’s climate by changing the radiative property of clouds. This paralleled the recognition of oceanic methane and volatile organic compounds as important biogenic actors in regulating climate. Over the following three decades, large strides have been made in elucidating the production and cycling of methylated sulfur compounds, particularly dimethylsulphoniopropionate (DMSP) and dimethylsulfide (DMS), and of C1 compounds. This session will bring together the organosulfur and volatile organic carbon communities to provide a summary of the state of the fields and highlight how the fields can move forward and capitalize on emerging techniques and technologies. We encourage submissions related to the production and cycling of DMS, DMSP, methane, and other C1-compounds. In particular, we will highlight research that combines interdisciplinary approaches for answering questions ranging from the molecular to global scales.
