This is a gamma spectroscopy lab where we use a suite of fallout radionuclide (FRN) and short-lived radionuclide (SLR) chronometers to understand modern change to atmospheric aerosols, forest ecosystems, physical landscapes, river systems, and the biogeochemical connections among them. Ongoing projects include high-precision measurements of atmospheric wet and dry deposition, chronometry and Hg  biogeochemistry of soils, hillslope erosion in the Arctic, headwater coupling between rivers and hillslopes, reconstruction of lake sedimentation and Hg chronologies, and more. 

We are a core community facility, providing high-precision gamma spectroscopy to over 30 collaborators at >20 institutions and agencies in USA, Canada and China.Fee-for-service: we offer commercial analysis and consulting services, contact Research Scientist Josh Landis for more information.
