Ralph von Frese
In 1969, Frese graduated B.A. cum laude from Park College in physics, mathematics, and German. He earned M.Sc. degrees in physics (1973) and geophysics (1978) and a Ph.D. in geophysics (1980) from Purdue University. He has taught at OSU since 1982.
He and Potts used gravity measurements by NASA's GRACE satellites to identify a 200-mile (300 km) wide mass concentration. This mass anomaly is centered within a larger ring-like structure visible in radar images of the land surface beneath the Antarctic ice cap. This combination led these researchers to speculate that it may have resulted from a large impact event.
