The first phase of this project was to develop and construct a series of solar powered radio buoys that would detect and wirelessly transmit the whale sounds to shore. The first of our buoys was activated in 2003, in Hawaii. Since then the buoys have evolved significantly and are more complex, more effective, and more reliable.We have moved on from moored buoys with radio transmitters, to using Wave Gliders® to travel to any position we like and transmit the live audio back to shore using cell phone signals. This allows us much better quality sound as well as other data transmission such as pictures. An added benefit of utilizing cell phone technology is the prevalence of cell towers. This means the Wave Glider based system can be sent and operate off the coast of most of the developed world.
