At least one AUV equipped with an integrated acoustic receiver and hydrophone is now used routinely as a telemetry platform to locate tagged fish in estuarine and shallow coastal settings in the eastern United States (Grothues et al.
The ship being measured will pass by the hydrophone at controlled conditions and speed at least 100 meters from the hydrophone array.
To listen to life underwater, scientists attach a hydrophone to a cable and without disturbing the fish, slip the hydrophone into the water, where two-minute recordings seem to generate enough data to compile a complete profile of a reef.
The intent was to decouple the hydrophone on the lower mooring line from the motions and violent pulls of a surface buoy, which is frequently buffeted by high winds and large waves.

In order to measure swimming speed, we used the last detection at a hydrophone at one gate and the first detection at the next gate to determine time of travel and distance between hydrophones.
For example, in an effort to redesign hydrophone mounts on a sonar system, Attenuate was molded into a cylindrical shaped sleeve to encase the system's hydrophones.
That means the ships would tow a hydrophone (a device that detects sounds underwater) and listen for submarine-made sounds, such as motor noise.
3) observed that artificially generated sounds recorded close to a hydrophone were free from acoustic artifacts.
