With a new technique, data from the deep ocean floor no longer needs cables to be rapidly transmitted to the surface. Konstantin Kebkal and his colleagues at the Technical University (TU) of Berlin have mimicked the communication methods of dolphins to develop innovative approaches, 
that can be applied for tsunami warning systems. With a newly developed system, various data can be transmitted without the need for cables, including images from the ocean floor and seismic measurements indicating potential tsunami risks.
Dolphins communicate with each other using sounds that travel through sound waves. Within certain ranges, these sounds can be transmitted over distances of up to 10 kilometers. Furthermore, these sounds convey a wealth of information to the dolphins. For example, they can distinguish whether a received signal is direct or has bounced off rocks or the ocean floor.
Building on these discoveries about dolphin communication, scientists in Berlin have developed a communication system capable of transmitting signals up to 2 kilometers over the ocean. Current experiments are underway to extend this range even further, potentially reaching distances of 6 or 8 kilometers.
