I was recently "awarded" the opportunity to go dive tending . Yes, diving happens here in Antarctica! Brrr, right?!? McMurdo, being located on the Ross Sea, brings in scientists to study the underwater world surrounding the continent. Sometimes the diving groups offer us, the "worker bees" of McMurdo, the opportunity to come along to help them as they do their dives. This particular time, I was selected to go which ended up being pretty fun and interesting!
Another girl, Alyssa, and I went with a research group studying the various environmental impacts of the underwater world and monitoring the recovery process over time. Alyssa and I helped the group load up their diving gear into a Piston Bully (a tracked vehicle made for snow and ice conditions) and drove out to the dive sight. The gear-up process is quite extensive to go for a dive. Since the water is extremely cold they have to make sure to dress warm enough under their dry suits, basically covering all exposed skin. The water temperature is actually below freezing but the salt content of the water makes the freezing point lower at 1.9 C (28 F) instead of 0 C (32 F). We assisted them in putting on their gloves, masks, assisting in zipping up suits, helping put on their tanks, weights, etc. Diving in frigid water, you want everything to be as water tight as possible, keeping the cold water as much off your skin as possible. The dives generally last about 45 min to an hour depending on how cold the divers get and how long they can stand it. Luckily, where this particular hole was cut through the ice, there was a hut with a heater over the top of it, so while Alyssa waited for the divers to surface again, we were just able to hang out in the warm hut, not all the dive spots afford this luxury of warmth. We got to watch them, the 4 divers, jump in and then waited for them to surface again to help them when they were ready to get out.
Looking down into the hole in the ice was really beautiful. Since the ice is thinner this year, the sunlight really penetrates through the ice and the hole in the ice glowed in this really beautiful blue. I could see the divers swim by occasionally, some 40-60 feet down. The water is so clear I could see clear to the bottom and could even see a few starfish and sponges here and there. Apparently the marine creatures here grow larger than usual. Some studies say it is because of the extremely cold water temperatures that slow the metabolism of the creatures causing them to grow bigger on a usual diet amount. Also there aren't certain predators that you would find elsewhere allowing things to live longer, threatened less.
When the divers surfaced, Alyssa and I helped pull their oxygen tanks up onto the hut floor since they are so heavy, which makes it easier for the cold divers to climb out. Two of the divers who went on this particular day were first-time divers in Antarctica. They were pretty excited about their dive! Before we left, the dive crew wanted to let Alyssa and I know that although they couldn't really allow us to polar plunge into the ice hole, if we just "happened to fall in" they would be there to help us out (wink wink). Alyssa went planning to "accidentally fall in" but I definitely was not planning to do that. The thought of it actually sounded quite terrible to me initially. For one, I am not super fond of cold water, let alone water that is below freezing and secondly, jumping into a dark hole into icy water with who-knows-what under there sounded terrifying! So Alyssa, though very nervous, bravely jumped...ugh, I mean...fell in:) When she climbed up the ladder out of the water, this strange inspiration and strong urge took over me that I had to do this too! If she did it and survived, I could too, ha ha! Here I am in Antarctica, and I have the opportunity to do something I will probably never get the chance to do again; I have to do it! Before I could change my mind I quickly stripped down to my "swim suit" and jumped in. The water is shockingly cold and takes your breath away but you are only in it for only a matter of seconds, instinct takes over on getting quickly getting out. Luckily, no strange, giant, Antarctic sea monster attacked me when I jumped in. I must say that it was very exhilarating (but also produced an instant brain freeze). I warmed up the moment I got out (another reason the warm hut was a bonus). I POLAR PLUNGED IN ANTARCTICA!!!! I'm glad that I got brave and did it:)

After we loaded the piston bully back up with all the gear and ourselves, I was able to convince the dive leader to let me drive the piston bully back to the station!! I had never driven one before and wanted to so I somehow sweet talked my way into doing it, ha ha! It was a bit strange to drive, steering more like a boat than a land vehicle. I kind of got the hang of it and was able to get us all safely from the ice back to the dive hut on station:) I didn't really know what to expect with this dive tending gig but it ended up being much more fun than expected! It definitely was a far better alternative to working!
