Today, both the underwater communication technologies and the sensor technology are mature enough to motivate the idea of underwater sensor networks. Underwater wireless sensing systems are envisioned for stand-alone applications and as an addition to cabled systems. For example, cabled ocean observatories are being built on submarine cables to deploy an extensive Fiber-optic network of sensors (cameras, wave sensors and seismometers) covering miles of ocean floor. These cables can support

In Figure 1 is illustrated the OBSEA underwater observatory having fiber-optic and power cable for communication with the shore station and acoustic modem for communication with underwater wireless instruments.
