Overarching Research Theme:
Climate change impacts across northern watersheds
|
Climate change is occurring more rapidly across northern latitudes than anywhere else on the planet, with potentially important consequences for ecosystem structure and function there. This theme runs throughout my work and has included the use of remote sensing to quantify changes in lake ice phenology, laboratory experiments to understand the impact of temperature on coastal sediment mercury transformations, quantifying the impacts of permafrost thaw and glacial melt on mercury mobilization, and conducting field experiments to assess the impacts of warming on methane CH4 fluxes from heath landscapes.
