CT006:
The Biogeochemistry of Dissolved Organic Matter


Session ID#: 22508

Session Description:
Dissolved organic matter (DOM) plays a major role for biogeochemical cycles in the ocean and on land. DOM contains as much carbon as all living biomass on the continents and oceans combined. The accumulation of DOM in the ocean over several millennia is enigmatic and contradicts established paradigms in geochemistry for organic matter stabilization. On the other hand, bacteria can only assimilate dissolved molecules, and DOM is therefore the main mediator for the flux of energy in marine and freshwater ecosystems. The DOM pool is now recognized as paralleling the sedimentary record as an information-rich set of tracers. These molecules carry the signatures of their source and subsequent journey through the environment. For this session, we invite contributions from all areas of research on DOM biogeochemistry. Since inland waters are important contributors of DOM to coastal margins, we also welcome research which focuses on DOM biogeochemistry across the freshwater-to-marine continuum. Molecular-level and interdisciplinary studies are particularly welcome. Also contributions that apply innovative analytical approaches, or identify novel concepts, fundamental challenges and the future directions of this fast growing field of research are encouraged.
