A member of Naval Oceanography Special Warfare Command deploys 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 using 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)
