CT44B:
Biogeochemistry of DOM and DOM-Microbe Interactions IV Poster
Session ID#: 93287
Session Description:
Dissolved organic matter (DOM) plays a major role for biogeochemical cycles in the ocean and on land. On the one hand, DOM accumulates in the ocean over several millennia, contradicting established paradigms in geochemistry for organic matter stabilization. On the other hand, DOM is the main mediator for the flux of energy in marine and freshwater ecosystems, as bacteria can only assimilate molecules in the dissolved phase. The thousands-to-millions of molecules which comprise DOM carry the signatures of their source and subsequent journey through the environment. This session will be split into two parts, where we invite contributions 1) from all areas of DOM biogeochemistry across various aquatic environments, including field, experimental, and modeling approaches which enhance our understanding of DOM quantification and its cycling in the environment and 2) which emphasize connections among organic biogeochemists, microbial ecologists, physicists, computational data analysts and all other scientists who are interested in advancing the progress at the intersection of microbiology and DOM biogeochemistry. 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.
