Erik Clapp
Erik Clapp spent many years of his life at ¶¶Òõ̽̽ 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.
