Jonathan M.G. Glen
I am a geophysicist with the U.S. Geological Survey working with the Geology, Minerals, Energy and Geophysics Science Center in Menlo Park, California. My recent research has mostly focused on applying potential-field, and rock- and paleo-magnetic methods to geologic and tectonic problems in the western U.S.
My work involves studies in potential field geophysics, rock- and paleo-magnetism, and geomagnetism, applied to:
