An impact hammer driving a 12" pine pile during testing to collect hydroacoustic data. Two researchers from the U.S. Army Engineer Research and Development Center’s Cold Regions Research and Engineering Laboratory were recently awarded the USACE Environment Quality Award for addressing a critical hydroacoustic data gap in the Endangered Species Act (ESA)-compliant permitting of impact and vibratory pile driving used in building coastal infrastructure such as piers, bulkheads and docks.
