American geophysicist

**Ralph R. B. von Frese** is an American [geophysicist](/source/Geophysicist) at the [Ohio State University](/source/Ohio_State_University) who identified the [Wilkes Land mass concentration](/source/Wilkes_Land_crater) in [Antarctica](/source/Antarctica) in collaboration with [Laramie Potts](/source/Laramie_Potts). He is also a professor in the Division of Earth and Planetary Sciences of the School of Earth Sciences at Ohio State University.[1]

## Career

In 1969, Frese graduated [B.A.](/source/Bachelor_of_Arts) *[cum laude](/source/Cum_laude)* from [Park College](/source/Park_College) in [physics](/source/Physics), [mathematics](/source/Mathematics), and [German](/source/German_language). He earned [M.Sc.](/source/Master_of_Science) degrees in physics (1973) and [geophysics](/source/Geophysics) (1978) and a [Ph.D.](/source/Ph.D.) in geophysics (1980) from [Purdue University](/source/Purdue_University). He has taught geophysics and Earth systems[2] at OSU since 1982.

He and Potts used gravity measurements by [NASA's](/source/NASA) [GRACE](/source/Gravity_Recovery_and_Climate_Experiment) satellites to identify a 200-mile (300 km) wide [mass concentration](/source/Mass_concentration_(astronomy)). 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](/source/Impact_event).[3]

Sponsored by NASA, the National Science Foundation, and the hydrocarbon industry, Frese's research is primarily on [archaeology](/source/Archaeology),[4] [satellite gravity](/source/Satellite_gravity), and [magnetic studies](/source/Magnetic_field) of the Earth, moon, and other planets.[5]

Frese has also authored or coauthored several journal publications and served on many government and scientific panels.[4]
