Members of Naval Oceanography Special Warfare Command prepare to deploy an autonomous underwater vehicle from a beach at Camp Pendleton, Calif., July 16, 2014. Navy personnel used the AUV as part of a joint hydrographic survey exercise with Marines from 2nd Intelligence Battalion, II Marine Expeditionary Force. One team of Marines measured water depths from the beach with the aid of positioning equipment while a second team used depth-finding sonar off the coast. The Navy tested its AUV in conjunction with the Marines as a way of exploring cross branch techniques and strategies. (U.S. Marine Corps photo by Sgt. Paul Peterson)
