Robotic underwater vehicle snaps first images seafloor beneath Antarctica Thwaites Glacier
2020/2/20
During the first study of the ocean floor beneath Antarctica’s Thwaites Glacier, scientists took images of the glacier's foundations. Thwaites now accounts for about 4% of global sea level rise, and r...
Mid-Ocean Ridge Exploration with an Autonomous Underwater Vehicle
Autonomous Underwater Vehicle Ocean
2015/7/22
Human-occupied submersibles, towed vehicles, and tethered remotely operated vehicles (ROVs) have traditionally been used to study the deep seafloor. In recent years, however, autonomous underwater veh...
