U.S. Army Engineer Research and Development Center’s (ERDC) Geotechnical and Structures Laboratory (GSL) team member, Kevin Taylor, swings a sledgehammer to create an energy source for a Multichannel Analysis of Surface Waves survey, while GSL’s Janet Simms, in background, monitors the generated data on a field computer at the Riverfront Park near Vicksburg, Mississippi. Simms supports ERDC University, a six-month program encouraging collaboration between the ERDC and USACE districts and divisions. (U.S. Army Corps of Engineers photo)
