With the increased use of underwater robotics, underwater navigation becomes more and more important. A research team from Naval Research Laboratory, the University of Washington, and Naval Surface Warfare Center has developed and tested an underwater navigation system that uses a spiral shaped acoustic wave to determine aspect. The single stationary beacon can provide a… »

As researchers around the world work to uncover new materials to combat marine biofouling, the US Office of Naval Research (ONR) is supporting the development of novel approaches that are proving to be effective at biofouling prevention. In fact, the Naval Surface Warfare Center at Carderock (NSWCCD) estimates that biofouling reduces vessel speed by up… »
