The biogeochemistry of dissolved organic matter

Session ID#: 256370

Session Description:
Dissolved organic matter (DOM) plays a major role in biogeochemical cycles in the ocean and on land. DOM contains more carbon than all living biomass on the continents and oceans combined. The persistence of DOM in the oceans over several millennia is enigmatic and contradicts established paradigms in geochemistry for organic matter stabilization.  Heterotrophic prokaryotes can only assimilate dissolved molecules, making DOM the main mediator for the flux of energy in marine 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, including in-situ, space-based observational and modelling studies. Since inland waters are important DOM contributors of coastal margins, we also welcome research which focuses on DOM biogeochemistry across the freshwater-to-marine continuum. Molecular-level and interdisciplinary studies including lab experiments and modeling approaches 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.
