Erik Clapp



Erik Clapp spent many years of his life at UVM pursuing geologic and environmental research. His MS dealt with water quality and his doctoral research used 10Be analysis of sediment to examine the source and rate of sediment production in three different arid region drainage basins. Erik's work included isotopic analysis of sediment depth profiles to calculate deposition rates.
