Norfolk-based Sonar Link claims to offer the fastest underwater data connection available, about five times the speed of the existing 38Kbps offerings. This means data for aquatic research projects by oil companies or academics can be collected in one week rather than three. The system works by sending an acoustic signal from a data collector on the sea bed to a base station, usually attached to a ship or oil platform. It is also good news for dolphins. The company claims the system is up to 800-times quieter than current underwater data transfer methods, which can generate the same amount of noise as a jet engine and normally disorientates sea creatures.
