BG2.12Biogeochemistry of wetlands, lakes and marine environments
|Co-Conveners: Klaus-Holger Knorr , Julia van Winden , Julia Beer , Caroline P. Slomp|
Biogeochemical cycles in aquatic systems play a leading role in global geochemical cycles. These ecosystems are susceptible to environmental changes and anthropogenic impacts, including climate change, nutrient and acidity input, and shifts in the hydrologic or temperature regimes. This session invites contributions analyzing biogeochemical cycling in marine environments, lakes and wetlands and environmental or anthropogenic impacts on them. They may address (I) effects of environmental change or anthropogenic activities on element budgets and cycling (e.g. carbon and nutrient cycling), (II) the evolution of these elemental cycles over earth’s history (III) changes in vegetation, microbial, or redox dynamics, (IV) influences of hydraulic interactions on biogeochemistry.
