MARS Science Node (image) University of California - Berkeley Share Print E-Mail Caption The Monterey Accelerated Research System (MARS) cabled observatory, a node for science instruments on the ocean floor 891 meters (2,923 feet) below the surface of Monterey Bay, is connected to shore by a 52-kilometer (32-mile) undersea cable that carries data and power. About 20 kilometers of the cable was used to test a new concept called photonic seismology on the seafloor.
