B41A:
Biogeochemical Cycling in Wetland Ecosystems: From Observations to Modeling I

Submit an Abstract to this Session

Session ID#: 6854

Session Description:
Wetlands are one of the key biogeochemical hotspots in the world. Located at the interface between terrestrial and aquatic ecosystems, wetlands develop unique hydrological regime, soils, and plant communities. Wetlands serve important biogeochemical functions by exchanging carbon and nutrients with the surrounding environment and transforming them to different forms. While these processes often vary considerably across space and time, little is known about the variability and controls of processes involved in biogeochemical cycling. This session invites papers that address topics in relation to the biogeochemical cycling of carbon, nutrients and other chemical compounds in various types of wetland ecosystems. Both observational and modelling approaches are welcome.
