The Geosc 483 geophysics course, taught by Dr. Andrew Nyblade, will begin work in the catchment today for hands on experience using geophysical techniques. Students will be making gravity, resistivity and seismic measurements along three profiles from the stream northward up slope. Common applications for the techniques include estimating depth to bedrock and the water table, as well as identifying faults and fracture zones, and delineation of geologic boundaries.
