Edward A Mankinen
Ed is a Scientist Emeritus with the Geology, Minerals, Energy, and Geophysics Science Center in Menlo Park, CA. He joined the USGS in 1964, retired in 2010, and returned as Emeritus in 2011. His career and current work focus in paleomagnetism/rock magnetism and conducting and interpreting gravity and aeromagnetic surveys through the Geophysical Unit of Menlo Park (GUMP).
For most of Edward Mankinen's 47-year career, he was associated with the Menlo Park Rock Magnetic Laboratory conducting various research projects in paleomagnetism/rock magnetism. Most of these studies were concentrated in the western U.S. but also included field work in Alaska, the Hawaiian Islands, and Antarctica. Beginning in 1996, Ed also became associated with the Geophysical Unit of Menlo Park (GUMP) and began conducting and interpreting gravity and aeromagnetic surveys. Most of these studies were conducted in and around the Nevada Test Site and in the eastern Great Basin. As an emeritus, he has continued work on projects in both disciplines.
