What's Wrong With This Report ?

What's wrong with the BBC News' report that "Submarine sends underwater e-mail"?
Its conclusion: "It was also the first time a submerged and moving submarine was able to communicate without giving away its position by surfacing or raising an antenna."

The Benthos equipment used sound energy transmitted from acoustic modems to send e-mails from USS Dolphin off the coast of California to San Diego and other underwater modems. While cruising 400 feet Dolphin transmitted data up three miles to a relay buoy then to land.

WillyShake and Bubblehead had posted news of PULSNET (persistent littoral undersea surveillance network) last month, the system to replace SOSUS regionally. Well Benthos also makes remotely operated vehicles (ROVs) and their improved e-mail-relay technology sounds like a natural component of a new littoral networking system (or a red herring).
