Jeffrey C. Wynn

From Wikipedia, the free encyclopedia

Dr Jeffrey C. Wynn (aka Jeff Wynn), is a research geophysicist with the US Geological Survey. He has served most recently as the Team Chief Scientist for Volcano Hazards, USGS ^[1] , and is based in the Cascades Volcano Observatory [1] in Vancouver, WA, one of the five USGS volcano observatories in the United States [2].

In his professional career, Wynn has served as vice president for R&D of Zonge Engineering [3], and in several rotational management positions in the USGS. These include Chief of the Office of Geochemistry & Geophysics, Chief of the Venezuelan Guayana & Amazonas Exploration Mission (“Jefe del Grupo Asesor”), where he was first author of the first complete geologic map of southern Venezuela, ^[2] and also published a mineral resource assessment for the roadless southern half of the country. ^[3] Wynn also served for four years as the Deputy Chief for Science of the USGS Saudi Arabian Mission before assuming responsibility for volcano research and monitoring as chief scientist for volcano hazards in the USGS (http://volcanoes.usgs.gov/jwynn/0biowynn.html).

Wynn has studied and published on the Wabar craters asteroid impact event in the Empty Quarter of Saudi Arabia, ^[4] and developed a new technology for mapping sub-seafloor minerals and buried wrecks using a physical property called induced polarization ("IP"), ^[5] and obtained two patents on the discovery. ^[6] A commercial version of the dragged-streamer technology was successfully tested in the Bismarck Sea in February 2005 and off the east coast of South Africa in a large-scale deployment during May - June 2007 [4].

Wynn has also done extensive geophysical mapping work ^[7] in SE Alaska [5], and co-developed an airborne electromagnetic technology to rapidly map groundwater in 3D deep beneath arid basins [6]. He successfully mapped the groundwater of the San Pedro Basin in southern Arizona and northern (Sonora) Mexico in three dimensions [7]. He has published over 230 articles, books, and maps in fields as diverse as geophysics, archeology, and astronomy [8]. In 2002-2003 he served as president of the Environmental & Engineering Geophysical Society [9]. He has also completed the month-long Federal Executive Institute training for senior Federal managers [10].

Wynn holds a 4th degree black belt in Budoshin (Japanese origin) Jujutsu [11] ^[8], and as a community service has taught numerous free self-defense clinics for women in northern Virginia and Vancouver, WA [12]. In 1999 Asteroid "9564 Jeffwynn" was named for him by the International Astronomical Union [13]. Jeff is an Advanced Open Water diver (PADI certification) and a CPR-AED Instructor (National Safety Council) [14].
