9 June 2013 What a Dive

One of the projects going on down here is to build a boat ramp to launch the zodiac boats. Zodiacs are small, inflatable, but surprisingly durable boats powered by outboard motors. The zodiacs on station can hold up to six or 10 people. The three dashing fellows you see are the divers who will be building this ramp – Steve Rupp, Britt Coates, and Christian Clark.

These aren’t just any divers mind you. These are divers who specialize or are trained in underwater construction work. That already takes a certain level of skill not only in working under water but skill in handling the tools and heavy equipment needed to complete the structures. Remember, we are in Antarctica. So add another layer of challenges to the mix – really, really cold water. Any guesses how long they can stay underwater at a time? Well, before I tell you, let’s look at their gear. Their helmets are called Superlites. Why, I have no idea because a single helmet weighs about 32 lbs.

They are awesome though. They have welding shields to protect their eyes. They will be using underwater jackhammers as well. The other impressive tool they have is an ultrathermic cutting rod. This rod can pretty much cut through or melt just about anything. In fact, it can get as hot as the surface of the sun. Anyone know what that is? 10,000 degrees F. You better know what you are doing. Speaking of heat, let’s get back to how they stay warm in water that is about 28 degrees F. With hot water suits, of course. It’s like a human rubber hot water bottle…sort of. Their dive suits have tubes throughout with holes in them that literally shower their bodies with warm water. The water is taken in and warmed. They don’t need air tanks because they will be using surface supplied air. So there you have it. I will hopefully be posting some video of their underwater work.

Okay, so how long can they stay under the ice cold water? If you guessed 3-4 hours you would be correct!
