Environmental Tracer Group

Welcome to the Environmental Tracer Group website. We are a collaboration of researches from the Devision of Geochemistry. We use tracers that are naturally present in the envronment, deliberately-injected and transient tracers to investigate earth science problems in the areas of oceanography, continental waters, paleoclimatology, geochronology, and geology.
