The good and bad..

Well, lets start off the latest happenings on a positive note!

Field training..

Every wintering expeditioner has to complete multiple forms of field training once on station. There is Survival training which is an overnight camp in an emergency shelter called a 'bivvy bag'. Field travel training which involves multiple days and nights out in the field navigating with maps, compasses and GPS (kind of orienteering), some do 48hr familiarisation training if they aren’t already familiar with this particular location then finally we do numerous SAR (Search and Rescue) training exercises in case of an unfortunate incident out in the field.

Field travel training this year involved Quad biking around the many Fjords of the Vestfolds, staying at Platcha hut at the base of the Antarctic Plateau, setting up a field camp and staying in a Polar pyramid tent and finally a sightseeing and navigation tour through 'Iceberg alley'. It was an amazing trip, we experienced most of the weather Antarctica has to offer, from icy cold winds and blowing snow to scorching sunshine that will burn any exposed piece of skin in the blink of an eye. Check it...

Now for the not so great stuff...

As some of you may have heard, we had an incident with one of our helicopters recently. We had 2x choppers out in the field checking out a rarely seen Emperor Penguin colony out past the Amery ice shelf. On the return voyage they experienced white-out conditions which is an occasional problem down here and also a very disorientating effect where you can lose sight of the horizon and all surface definition.

One chopper clipped the ground while attempting to move out of the 'white-out' area. The other Heli landed nearby and proceeded to assist the passengers of the downed aircraft. Miraculously they were all breathing and were immediately stabilised by the second crew.

Meanwhile we received the call on station and proceeded to make plans for a rescue. Luckily we had 2x Canadian Kenn Borek crews stationed here with a Twin Otter and Basler DC3 fixed-wing aircraft. Most of the rescue can be read about here: http://www.smh.com.au/national/antarctic-helicopter-crash-survivors-had-luck-on-side-20131206-2ywom.html

As expected an incident like this can affect the station greatly, which it did and has. From the outside it may look like these people are just work colleagues but in reality we had been through quite a lot together from training, living on the ship and at station and we knew every member on a quite personal level.

I also had a challenging and unexpected role to play as I am part of the Lay Surgical team with the job of assisting our Doctor with incidents such as these. I wont go into detail for obvious reasons but this was something I have never experienced before but I am very proud to be a part of. I was also asked to help monitor the patients during the medivac to Casey station where they were picked up by our A319 Airbus to be returned to Hobart hospital. 

It was nice to visit one of our other stations for a few days but it would have been better to be under different circumstances...

They have some impressive machinery up there!

  1. Hi Corey,

    Though it's somewhat difficult to tell from the photo and not hold it in my hand I'd say that's a pretty classic metamorphic rock (cooked deep underground) called a gneiss. The banding is formed by shearing deep underground over geological time (many many millions of years). Shearing is kind of like pushing a deck of cards from the bottom on one side and the top on the other so the cards slide over each other, this stretches the rock when it's in a kind of plastic state due to the pressure and heat down there, thus bands form. I'd take a stab and say that the rock is Archaean aged, somewhere around 2500 - 3000 million years old (2.5 - 3 billion). So pretty damn old.. Most of Antarctica (theoretically) is ancient cratonic rock, like in Western Australia (Yilgarn and Pilbara cratons) which you may have heard of, so this type of rock would be pretty common there, along with other metamorphic rocks. Antarctica was about 100 million years ago still completely attached to the southern margin of Australia and only completely separated about 30 million years ago, so the Geology has similarities to the western 2/3 of the country. Would like to head down to Antarctica, and not for lack of trying, getting a job down there is tough with my skill set. Stay well and great blog.
