Our ability to understand biogeochemical cycles of carbon, nitrogen and phosphorus and other elements in aquatic ecosystems as well as biotic evolution and ecosystem functioning has evolved enormously thanks to advancements in in situ sensor measurements, laboratory techniques and predictive models. The aim of this session is to demonstrate how this methodological advancement improves our understanding of coupled hydrological, biogeochemical and ecological processes in aquatic environments and how it decodes faunal and ecosystem functional responses. In particular, our session focuses on improving the identification and quantification of the sources, delivery pathways, transformations and environmental fate of carbon and organic matter, nutrients, sediments and emerging contaminants in aquatic environments. Additional emphasis will be placed on biogeochemical interactions affecting aquatic organisms. In this multidisciplinary session, we welcome presentations on applications of novel techniques to improve our understanding of aquatic environments, , their biotic evolution, and robust data-driven and modelling approaches for advanced processing of aquatic biogeochemical data. As hydrological, biogeochemical, and ecological processes undergo accelerated change, this session welcomes also studies presenting approaches and tools to monitor, model, and predict water quality and sensitivity of aquatic ecosystems to global change and human disturbance.

The session is co-sponsored by JpGU.
