Nearly 80 years ago, the USS Grunion submarine sank on its inaugural mission during World War II, taking the lives of 70 sailors with it as it plunged to the bottom of the Pacific. Now, after years of searching, a team looking for WWII-era submarines has found the Grunion's bow about 2,700 feet (820 meters) under the water's surface, off the coast of the Aleutian Islands in Alaska.
Upon finding the long-lost bow, the team used autonomous underwater vehicles (AUVs) and advanced photogrammetry imaging to create 3D images of the underwater vessel.
"This goes so far past video or still imagery, it truly is the future of recording historical underwater discoveries," ocean explorer Tim Taylor, of the Lost 52 Project, a group searching for the 52 submarines that went missing during WWII, said in a statement.
