Videocameras, some of them tethered to research vessels, are going where humans can't, and scientists with high-speed connections can now operate them from the laboratory. In one project, a seafloor robot is exploring underwater volcanoes off the Pacific coast; the high-definition video stream is uplinked to satellite, downlinked at the University of Washington, and sent over high-bandwidth connections to researchers and students. Another camera, shown above, is being used to study mantas, large tropical fish that inhabit the waters around Hawaii, after a three-month tryout at California's Monterey Bay Aquarium. Registering with The Manta Network may get you a chance to control the camera, though that function doesn't seem to be working right now.
