a self-powered undersea robot capable of descending 11,000 meters — deeper than any existing research vehicle. The new robot is described as a hybrid because it will be able to operate either connected to a fiber optic umbilical or in a free-swimming mode. The navigation and control systems will employ technology developed by members of the Whiting School of Engineering's Department of Mechanical Engineering at Johns Hopkins University.

"The HROV will enable, for the first time, routine scientific research in the deepest parts of the ocean, from 6,500 meters to 11,000 meters — a depth we currently cannot reach," says Richard Pittenger, WHOI Vice-

President for Marine Operations. "It will also afford access to other very hard to reach regions, such as under the Arctic ice cap. The HROV's real-time, wide-band link to the surface will put the researcher in the loop to view, assess and command the vehicle throughout the duration of dive missions. It is the first capable and cost-effective technology that will enable scientists to pursue research projects on a routine basis in areas they have long wanted to study, but have been unable to reach. HROV technology will help answer many questions about the deep sea."
