The U.S. Army Engineer Research and Development Center's Environmental Laboratory, U.S. Geological Survey and partners install the underwater Acoustic Deterrent System weldment at Lock and Dam #19 on the Mississippi River near Keokuk, Iowa, Jan. 25, 2021. The uADS runs perpendicular to the lock's approach channel walls and is part of a study to understand how invasive Asian carp respond to acoustic signals. The research team believes that invasive carp will perceive the sounds from the uADS to be coming from predators in their native environment – dolphins. If the deterrent is effective at controlling upstream movement of Asian carp with limited effects on native species, this or similar technology could be deployed at other critical locations to help prevent the spread of invasive Asian carp.
