Brief synopsis of the session:
Productivity and structure of most aquatic ecosystems depend on the nutrient supply. In most freshwater systems, phosphorus availability limits growth of primary production. In these systems, the sediment-water-interface is a hotspot for several biogeochemical processes including phosphorus retention or release. In this session, we want to focus on the processes occurring at the water-sediment interface and the consequences of the phosphorus cycle for the ecosystem. Specifically, we invite contributions which deal with phosphorus adsorption/desorption, mineralization and biological uptake in aquatic systems as well as with the consequences of global warming and land use changes on these processes.
