BG6.4

Inland waters and wetlands (both brackish and fresh) form networks that represent vital conduits through the landscape; receiving, transporting, transforming and emitting carbon. To better constrain the role of freshwater networks within the global carbon cycle, it is pivotal to study the exchange and transformation processes that take place at interfaces, both between the network’s aquatic compartments (as e.g., between anoxic and oxic waters) but also conterminous to the terrestrial and atmospheric realm (e.g., sediment-water, water-air). Such interfaces feature distinct physical and biogeochemical gradients and often represent biogeochemical “hot spots” in the landscape.

In this session, we will address the biological, biogeochemical and physical processes that control the cycling of carbon at aquatic interfaces, especially with regard to the formation and emission of the greenhouse gases CO2 and CH4, and associated redox driven processes.

We invite presentations on recent empirical and conceptual advancements at the forefront of carbon cycling along the land to ocean aquatic continuum, with a focus on processes that occur at aquatic interfaces. We encourage contributions that employ novel biogeochemical, molecular biological and modeling approaches directed towards obtaining a fundamental and mechanistic understanding of the active controls on carbon processing and storage across freshwater ecosystems.
