This project began with an effort to understand and utilize environmental and deliberately produced electromagnetic (EM) signals in the coastal ocean. Our studies were undertaken to provide a means to communicate with and guide autonomous underwater vehicles (AUV) and other autonomous sensor systems, such as moored instruments. There is a need for non-acoustical methods to navigate and control AUVs, communicate with autonomous instruments, and detect submerged and buried objects in shallow water. In principle, extremely low-frequency EM signals.
