Jennifer Harden

Biography

I am Scientist Emeritus at the U.S. Geological Survey where I have served as research soil scientist since 1982. I have contributed to geologic mapping, geochronology, geologic faulting, paleoclimate, landform evolution, carbon cycling and biogeochemical interactions in soil systems. My most recent research addresses the role of soils in carbon and nutrient cycling, with an emphasis on landscape disturbances such as permafrost degradation, erosion/sedimentation, and wildfire.
