By using a combination of aboveground and underwater sensing devices, and feeding that information into sophisticated computers, a deep sea robotics and submarine company in Alameda says it can produce an "MRI" for the Delta that would allow experts to better target repairs. The 14-year-old company already has a $500,000-plus contract with the University of Northern Illinois to build an underwater vehicle that is designed to travel 1,000 meters through a 22-inch bore in an Antarctic ice sheet. Once beneath the ice sheet, the vehicle is designed to "unfold itself like kid's transformer toy" and explore the underside of the ice as part of a scientific investigation into climate change, Liz Taylor said. In the Delta, DOER is proposing a combination of ground- penetrating radar and other sonar and radars. Other sensors, such as infrared, could be incorporated later. Other companies have suggested magnetic imaging, said Dave Mraz.
