The U.S. Army Engineer and Development Center’s Justin Wilkens, a research biologist with the Environmental Laboratory, checks the waypoints using the SubSeaSail’s G6 navigation software on his laptop. The unmanned surface vessel was taken to Vieques, an island off the coast of Puerto Rico, for a demonstration by Wilkens and a team of ERDC-EL research biologists, including Dr. Guilherme Lotufo and Dr. Mark Ballentine. The USV gathered data indicating the presence of munitions constituents from unexploded underwater ordnance, a problem at sites around the world.
