Iron oxide nanoparticles, e.g., ferrihydrite, have major impact on biogeochemical cycling of carbon and trace metals in soils. Climate and environmental change are having profound impacts on humankind. Rising seas and temperatures are causing increasing flooding, salt water intrusion, and melting of ice and permafrost soils. The impact of these processes on Fe-oxide nanoparticle interactions with carbon and metal(loid)s is not well understood. For example, how do rising seas affect transformations of Fe-oxides and As?  Under changing climatic conditions, how will sequestration of C by Fe-oxide minerals be impacted, and resultant mobility of elements? This presentation will explore these questions, and others, over a range of spatial and temporal scales.<br/><br/>
