Summary: Although I cannot think of the last time I was scuba-diving and had a burning desire to check my email, I am excited for the prospect of underwater internet. The intended purpose is not for watching "Finding Nemo" with the fish, but for detecting tsunamis. While normal wi-fi using radios waves, due to the limited range and stability in water, sound waves will be used instead. This technology has been in use before but it was cumbersome to share data between research teams. The University of Buffalo team is hoping that this will create a shared standard so that anyone with a computer or smartphone could be instantly alerted when a tsunami is approaching.
