Over the past few weeks, the global media has been making a big deal about a proclaimed "Race to the Bottom". This "race" refers to several individuals and companies seeking to reach the bottom of the Mariana Trench, the deepest part of the planet's oceans, in a variety of different submarines. Of course, this is really not a race at all, since two men (Jacques Piccard and Don Walsh) already made the descent over 50 years ago as part of a U.S. Navy exercise. In fact, as Walsh likes to put it, this current frenzy is really just a "Race for Second".
That being said, there is no denying that this recent crop of adventurers and explorers is helping to rekindle a worldwide public interest in the oceans, manned submersibles, and exploration in general. Here is a brief overview of each participant in this "race":
James Cameron
The famed director of mega-hit films like the Terminator and Alien series, Titanic, and Avatar, has had a long-time fascination with the oceans, manned submersibles, and exploration in general. He is close friends with the recognized godfather of research submarines, Anatoly Sagalevich, he has made several descents to the Titanic, and he has produced underwater documentaries such as Aliens of the Deep and Ghosts of the Abyss. Overall, he has over 70 dives in deep submersibles. He leads a NatGeo-backed team that has spent almost eight years developing a one-person submarine specifically for the attempt to reach the bottom of Challenger Deep within the Mariana Trench. If successful, Cameron will set the world solo diving record, and the team will boast the world's deepest diving active submarine.
Outlook. Cameron will likely make the full descent by the end of March 2012.
Richard Branson
In late-2010, sailboat racer Chris Welsh decided to honor one of his heroes, world-record aviator/sailor/explorer Steve Fossett, by taking up the challenge he was working on when he perished in a plane crash in 2007: the world solo diving record to the bottom of the Mariana Trench. Fossett had commissioned Graham Hawkes to design a submarine specifically for the world-record attempt, but he died before the sub got to its sea trials. Welsh purchased the unfinished sub from Fossett's estate, hired Hawkes to complete the project, and partnered with Richard Branson, Fossett's long-time partner, to create Virgin Oceanic ("VO"). While Branson has garnered the media spotlight during this "race", VO still remains Welsh's passion project, expanded to include diving to the deepest points in each of the world's five oceans.
Outlook. The sub has not yet passed its pressure tests, so it is unlikely that VO will make its dive attempt until late-2012.
Triton Submarines
Triton is a reknowned builder of submarines specifically tailored for use aboard luxury yachts. The company is fronted by master-marketer Bruce Jones and headed by acclaimed sub expert Patrick Lahey, and together they have delivered six submarines ranging in depth capabilities from 1,000 feet to 3,300 feet and carrying 2-3 passengers in different configurations. They have extended their unique sub designs to include a three-person Full Ocean Depth ("FOD") model 36000/3, which could reach the bottom of the Mariana Trench.
Outlook. Triton is still looking for its first client to pay for the development of the FOD 36000/3.
Deepsearch
The brainchild of famed ocean explorer Sylvia Earle and initially backed by Google Chairman Eric Schmidt, the Deepsearch project is taking a unique "open source" approach to community-based design and development of a deep-diving submarine. The project is spearheaded by Deep Ocean Exploration and Research, an ocean engineering firm headed by Sylvia's daughter, Liz Taylor.
Outlook. This project is still looking for additional financing to move beyond initial design stage.
