Post-Symposium Resources

We were pleased to have an impressive presentation line-up for the International Symposium on Biogeochemistry of Wetlands & Aquatic Systems

BioGeo 2025 featured more than 150 talks and posters presented by those actively engaged in applying principles of biogeochemistry to solve environmental and social problems from a wide range of systems. This year’s theme sought to acknowledge the critical coastal zone where freshwaters from rivers and lakes discharge into estuaries and coastal ocean waters, and where changes in runoff timing and discharge volume can cause dramatic shifts in major drivers of biogeochemical cycling including temperature, salinity, nutrients, sediment, and contaminant loading. The goal was to improve our understanding of the role wetlands and aquatic systems perform in regulating and mitigating impacts of global climate change and sea level rise.
