This is the official "I don't get it"-part. Ships have sonars, right? Make them better? It seems awfully bigger investment to cover the whole sea with sonars, than to embed ships with better sonars? Or is the sonar less efficient from near surface? Well couldn't it then be floated below?
Also, it seems, the wavelength of 10-15 kHz will be disturbing to marine life like dolphins and whales. *sigh*
