"SONAR: renders ocean floor transparent"
A breakthrough in sonar technology may soon make it possible to more accurately detect and map underwater artifacts, such as mines, even when they are buried. "Our results are from simulations, but they show that some relatively simple changes to standard sonar equipment will result in a much simpler and effective means of detecting underwater mines," said David Pierson, a Johns Hopkins University scientist who invented the technique for his dissertation under professor David Aspnes at North Carolina State University.
