{{Short description|American geophysicist}} '''Ralph R. B. von Frese''' is an American [[geophysicist]] at the [[Ohio State University]] who identified the [[Wilkes Land crater|Wilkes Land mass concentration]] in [[Antarctica]] in collaboration with [[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.<ref>"Von Frese is a professor in the Division of Earth and Planetary Sciences of the School of Earth Sciences at Ohio State University." - [https://thebulletin.org/biography/ralph-von-frese/] (Bulletin of the Atomic Sciences)</ref>

== Career ==

In 1969, Frese graduated [[Bachelor of Arts|B.A.]] ''[[cum laude]]'' from [[Park College]] in [[physics]], [[mathematics]], and [[German language|German]]. He earned [[Master of Science|M.Sc.]] degrees in physics (1973) and [[geophysics]] (1978) and a [[Ph.D.]] in geophysics (1980) from [[Purdue University]]. He has taught geophysics and Earth systems<ref>"RALPH R. B. VON FRESE is Professor of Earth Sciences at The Ohio State University, where he has taught undergraduate and graduate courses across geophysics and Earth systems since 1982." - [https://assets.cambridge.org/97805218/71013/frontmatter/9780521871013_frontmatter.pdf] (Cambridge University Press)</ref> at OSU since 1982.

He and Potts used gravity measurements by [[NASA|NASA's]] [[Gravity Recovery and Climate Experiment|GRACE]] satellites to identify a 200-mile (300&nbsp;km) wide [[mass concentration (astronomy)|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]].<ref name="big bang">{{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| url-status=dead| archiveurl=https://web.archive.org/web/20160306140004/http://researchnews.osu.edu/archive/erthboom.htm| archivedate=March 6, 2016}}</ref>

Sponsored by NASA, the National Science Foundation, and the hydrocarbon industry, Frese's research is primarily on [[archaeology]],<ref name=":0">"His research has focused mostly on archaeological and planetary applications of gravity and magnetic fields, and he has authored or co-authored more than 100 journal publications and served on several government and scientific panels." - [https://assets.cambridge.org/97805218/71013/frontmatter/9780521871013_frontmatter.pdf] (Cambridge University Press)</ref> [[satellite gravity]], and [[magnetic field|magnetic studies]] of the Earth, moon, and other planets.<ref>"Sponsored largely by NASA, the National Science Foundation, and the hydrocarbon industry, his research focuses mostly on satellite gravity and magnetic studies of the Earth, moon, and other planets." - [https://thebulletin.org/biography/ralph-von-frese/] (Bulletin of the Atomic Sciences)</ref>

Frese has also authored or coauthored several journal publications and served on many government and scientific panels.<ref name=":0" />
