The image above shows agricultural landscape south of Clear Lake, Iowa. The light-colored patches in plowed fields are areas where dark-colored, organic-rich topsoil has been lost to erosion. UMass Amherst geologist and geochemist Isaac Larsen, an expert in soil production, erosion, human impact and the evolution of the agricultural landscape, has been awarded a three-year, $265,000 New Investigator Program grant from NASA’s Earth Science Division to study where soil has been lost. Larsen's use of remote sensing is a way to look at soil erosion on a broad scale. Learn More. Image courtesy GoogleEarth
