Ralph von Frese

Ralph R. B. von Frese is an American geophysicist at the Ohio State University who identified the Wilkes Land crater with Laramie Potts.

In 1969, von Frese obtained a 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 suggests that it is the result of a large impact event.cite web| url=http://researchnews.osu.edu/archive/erthboom.htm| title=Big Bang in Antarctica -- Killer Crater Found Under Ice| publisher=Research News| first=Pam Frost| last=Gorder| date=June 1, 2006]
