Today, Sir Richard Branson, American sailor, pilot and explorer Chris Welsh, and submarine designer Graham Hawkes launched Virgin Oceanic, a project to explore "the last frontiers of our own Blue Planet: the very bottom of our seas." .
The project includes a partnership with Google: "Using their mapping technology, Google hopes to chronicle the dives as they happen and share discoveries, footage and record breaking achievements with the world."
