Current Research: Marine Production of DMS and its Interaction with Climate

This project (ESR V) investigates the feedback between climate and oceanic phytoplankton through the sulphur cycle.
Dimethylsulphide (DMS) is a volatile sulphur compound produced from the algal secondary metabolite dimethylsulphoniopropionate (DMSP) by complex biotic interactions in marine ecosystems. The atmospheric oxidation products of DMS affect the radiative properties of the atmosphere by reflecting solar radiations and by affecting the concentration of cloud condensation nuclei (Charlson et al., 1987). DMS is the main natural source of sulphate aerosol to the atmosphere and the major route by which sulphur is recycled from the ocean to the continents.
The project includes: 1) the implementation of a sulphur cycle with species-dependent production of DMSP in the Dynamic Green Ocean Model (see below), 2) the inclusion of ocean DMS fluxes in a climate model, 3) running simulations for future climate scenarios including climate change. Furthermore, the impact of ocean acidification on DMS emissions has been studied in a mesocosm experiment.
This work is being undertaken in the framework of green ocean, an international project aimed at developing a community model of ocean biogeochemistry for applications to Earth system problems. It contributes to science objective 5 (Quantify impacts of climate change on terrestrial and oceanic biogenic emissions of aerosols and chemically active gases, and their effects on tropospheric chemistry) of GREENCYCLES. It is linked with the project of Nicholas (ER4).
