Preparing for winter
86.80033 deg S
54.45187 deg E
3151 meters above sea level
Maximum & Minimum temperatures: - 21 to - 30 °C
A fundamental approach is to direct all vehicles and modules against the direction where we expect the storms to come from. We consulted the meteorologists at South Pole before we placed our sledges and modules side-by-side with some 50 meters distance between them. Also, to avoid snow drift it is important to get equipment above ground. Most of our gear is carefully strapped down on sledges and thus fine. However, we had to build a berm for one of the vehicles. We decided to use empty fuel drums as the platform (see photo). Thus, we secured the drums and made a decent platform for the TL-6 vehicle in one go.

The Last Polar Bear: Facing the Truth of a Warming World
The Last Polar Bear records and celebrates one of nature’s most majestic creatures — the polar bear — and examines how global warming is affecting the fragile, complex Arctic environment.
Polar bears use sea ice to move about, find mates and hunt for seals. As temperatures warm, the loss of the pack ice directly impacts their ability to survive. Scientists agree that Arctic ice is disappearing at an alarming rate. Last summer, sea ice levels plummeted to their lowest since satellite measurements began in 1979. And a new scientific study by the U.S. Geological Survey, released last fall, predicts that two-thirds of the world’s polar bears, including Alaska’s entire population, may disapp...

Establishing Camp Winter
86.80033 deg S, 54.45187 deg E
3151 meters above sea level
Maximum & Minimum temperatures: - 22 to - 33 °C
We are now in a situation where it is impossible to get all our equipment to the South Pole this season. The alternative to go onwards with two vehicles and light loads, even receiving assistance if this light traverse experiences problems, was considered unfavorable. We would then have ended up in a situation where our vehicles and equipment were located at two different places at the start of next season. Thus, we have decided to establish a winter camp here. Personnel, scientific samples, instruments and all other gear that can not stand the cold winter will be airlifted to South Pole with a Basler aircraft from Antarctic Logistics Centre International...

Chinook stops
86.80033 deg S, 54.45187 deg E
3151 meters above sea level
Maximum & Minimum temperatures: - 25 to - 35 °C
Today we experienced a break-down of the transmission transfer-case on Chinook. This means that Chinook shares the same destiny as Sembla and is not operative anymore. Functional spare parts are unfortunately not available. Thus, we are not able to pull all our equipment to the South Pole without receiving support. Currently, we are exploring the possibilities to receive support from the United States Antarctic Program (USAP).

The hazards of working in the world's most inhospitable environment
We had a slight “event” a week or so ago, when our group was at a site called Mt. Paterson. Mount Paterson is about 550 miles west of McMurdo, somewhat near the coast. I would have put a post up about this earlier, but it was a somewhat sensitive issue. Enough time has elapsed now, and I think it is important to talk about, so I’m putting up some photos. In short, we had a plane crash in the Basler. If you have read previous posts, you will know that a Basler is a fixed wing aircraft, slightly larger than a Twin Otter, and therefore capable of carrying more weight. It uses skis to land, just like a Twin Otter. I wasn’t on the flight, another member of our group, Bob, ended up taking my place. There were six people from out group total (3 GPS, 3 seismic) and 4 people from fixed wing...

Last science stop completed
13 Jan 2008
86.05767 deg S, 55.06667 deg E,
3251 meters above sea level
Maximum & Minimum temperatures: - 25 to - 36 °C
It was with mixed feelings that we finished the last science stop. On one hand, it was good to know that a very successful field program was completed. On the other hand, it was a bit sad to know that the field season comes to an end soon. After lunch we packed up. A lot of reorganization was needed since only three vehicles are operative now. After dinner we started out on our non-stop driving to the South Pole. All vehicles performed well and the spirits were once again high – “only” 600 km to go…

And the Howling Wind Goes On
Yeah, you better believe it. The wind has been ferocious here. It is hard to describe just what a physical presence it has, its own personality each day. One day its a continuous ground blizzard that makes getting between the tents “fun.” Some nights you can barely sleep because the your tent is being rocked about, with gusts occasionally bending it completely out of shape. You lie there wondering if you’re about to blow away. When the lulls come they are glorious, the silence is absolute, much more so than anything you can find around McMurdo, where there is always the noise of a generator or a vehicle backing up somewhere.
The people here are a nice bunch. They seem pleased to have scientist in their mix. The staff are regular explorer types mostly, with a few hardy ...

The Howling (wind)
Patriot Hills is a nice spot. Well sort of, its very pretty to look at, really rather good to eat at, but not so great when the weather is concerned. The wind blows constantly here, which is why the camp is actually here. The wind screams down from the mountains and strips the top layer of snow off, leaving slippery, polished blue-ice, that very large Russian transportation aircraft can land on. Unfortunately most of that snow ends up in the tented camp a little bit to the north.
When I say the wind screams, I mean it just absolutely howls through the camp, throwing up whirlwinds of snow, battering tents, and putting spindrift into any available orifice. It’s a tangible presence here twenty-four hours a day. Anything not locked down is gone with the first ferocious gust. W...

On the way to Patriot Hills
It’s been a few days since anything really happened. There was the New Year, which was ushered in with much hilarity and scotch, and the helo-hanger party where the blue grass and rock bands from Ice Stock played again. And there was the visiting members of Congress that we had to talk to, and several fire drills, but conspicuously there wasn’t much work to be done.
Weather has not been our friend, and we have had some logistical knock on effect from the plane crash that our group was involved in earlier in the season (Google "Antarctica Basler", to read-up on it, if you are so inclined).
I’m writing this from the belly of a LC130 ski-equipped Hercules aircraft. Four of our team, myself, Brian Bonnet, Don Voigt and Thomas Nylen (yeah him again) are l...
