WHOI's low-frequency broadband acoustic system being deployed

It will be like going from black-and-white television to high definition color TV – that’s how researchers at America’s Woods Hole Oceanographic Institution (WHOI) have envisioned an upcoming leap forward in undersea acoustic imaging. Tim Stanton and Andone Lavery have developed and tested two broadband acoustic systems that leave conventional single-frequency systems eating their dust… or water droplets, or whatever. Developed over 20 years, the new technology could revolutionize oceanography, and also has huge commercial and military potential…
