This is really cool -- check out the article on ScienceDaily.
In a multi-institution effort managed by the Monterey Bay Aquarium Research Institute (MBARI) and funded by the National Science Foundation, 52 kilometers (32 miles) of cable were laid along the seafloor of Monterey Bay. This undersea cable will provide electrical power to scientific instruments, video cameras, and robots 900 meters (3,000 feet) below the ocean surface. It will also carry data from these instruments back to shore, for use by scientists and engineers around the world.MBARI is a very cool organization, I was able to go out on a short research cruise last fall, which was a great experience. Very high tech...exploring the deep sea floor is like exploring another planet. It will be exciting to see how well this new system works out.
