Undersea sensors often include an acoustic modem buoyed above a seabed mooring or suspended beneath a surface buoy. In both cases, a vertical cable is subjected to horizontal water currents. This thesis examines the two cases, the first characterized by a cable moored to the bottom of the ocean with a buoyant end, and the second being a cable suspended or towed from a surface buoy or Unmanned Surface Vehicle ...
The deep ocean is characterized by sound propagation that can support wide-area surveillance through the use of distributed acoustic sensors near the seabed. Such a deep-water sensor network is potentially enabled by phenomena such as Reliable Acoustic Path (RAP) and Deep Sound Channel (DSC) through which undersea network nodes can transmit and receive data across long distances. To provide a theoretical understanding of system effectiveness, the Bellhop acoustic modeling program ...
