Scientists place objects that mimic munitions on the seafloor off the coast. Each object is equipped with acoustic transponders that let scientists track how the objects move over time, particularly before and after storms. Undersea instruments measure waves, currents, and sand and mud movement to learn how UXOs are moved and/or buried by sand and mud.
U.S. coastlines still have a lot of unexploded ordnance, or UXOs, left offshore by military exercises in the 1940s and 1950s. WHOI scientist Peter Traykovski and colleagues are investigating where UXOs are and how they are moved and buried in different areas and different conditions along the coast.
