Ice Stories: Dispatches From Polar Scientists » Basler aircraft http://icestories.exploratorium.edu/dispatches Mon, 15 Nov 2010 20:40:36 +0000 http://wordpress.org/?v=2.9.2 en hourly 1 Field Deployment http://icestories.exploratorium.edu/dispatches/field-deployment/ http://icestories.exploratorium.edu/dispatches/field-deployment/#comments Fri, 08 Jan 2010 21:36:34 +0000 Lucas Beem http://icestories.exploratorium.edu/dispatches/?p=2344 WHILLANS ICE STREAM, WEST ANTARCTICA– We landed at our field site after a three hour flight from McMurdo Station. We arrived on what is called a Basler. This plane is a modified DC-3 and was built in the the 1950s. Climbing out of the plane we were in a white flat expanse. We were lucky: the weather was ideal, sunny and calm winds. After unloading our gear, two snowmobiles, three drums of fuel and survival gear (tents, food and clothing), it was time for the plane to leave.

Part of the safety protocol is to have the field party pitch one tent before the plane can leave. This is in case something happens, weather or injury, there can be a haven out of the elements. In certain scenarios, it might just be the difference between life in death.

As you’ll see, we pitched our tent much too close to the plane and we were bowled over by the force of the propellers. Moments later the plane disappeared into a cloud of snow. Silence and we were alone.

Interview with the Outgoing South Pole Winter-over http://icestories.exploratorium.edu/dispatches/interview-with-the-outgoing-south-pole-winter-over/ http://icestories.exploratorium.edu/dispatches/interview-with-the-outgoing-south-pole-winter-over/#comments Thu, 05 Nov 2009 00:50:45 +0000 Nick Morgan http://icestories.exploratorium.edu/dispatches/?p=1955 SOUTH POLE, ANTARCTICA– Well, after numerous weather delays, I arrived at the South Pole on October 27th. Initially I was suppose to be flying in on a DC-3 Basler but as you quickly learn here plans change on a dime, and ended up flying in on a Hercules LC-130. There were 40 of us on the plane and the weather forecast for us actually being able to land was looking grim. However, to our surprise (and relief), we did land.

The previous winter-overs running the Atmospheric Research Observatory, LTJG Marc Weekley and engineer Patrick Cullis (aka Cully), were there to greet me at the ski-way, and help me with my bags. Winter-overs are people who stay on station for the 8-9 long months in which there are no flights into or out of the Pole. Temperatures are just too cold during this period for flights. Many winter-overs like Marc and Cully spend the S. Hemispheric summer months here as well making it a full year. After a few days of turnover with Marc and Cully (who were extremely patient and helpful for having just spent a winter in isolation), I was able to catch up with Marc for an interview on his thoughts, feelings and advice on spending a year at the South Pole.

Visitors on the Antarctic Plateau http://icestories.exploratorium.edu/dispatches/visitors-on-the-antarctic-plateau/ http://icestories.exploratorium.edu/dispatches/visitors-on-the-antarctic-plateau/#comments Wed, 16 Sep 2009 17:54:22 +0000 Zoe Courville http://icestories.exploratorium.edu/dispatches/?p=1818 HANOVER, NEW HAMPSHIRE– In the middle of our traverse, we had the rather surreal experience of being visited by a French film crew making a documentary about research work in Antarctica. The crew flew in on a Basler, the somewhat debatable name of the converted DC-3 aircraft commonly used in Antarctica. Not only were these the only “new” people we’d seen in a long time, but the arrival of a plane, with it’s promise of transport back to the “real” world was enticing. A quick head count assured that none of our group had snuck on board, and meant we were all in it for the long, long haul back to Troll. Even better, the Basler pilot left us with a bit of a treat.

One Month in the Deep Field, Part 1 http://icestories.exploratorium.edu/dispatches/one-month-in-the-deep-field-part-1/ http://icestories.exploratorium.edu/dispatches/one-month-in-the-deep-field-part-1/#comments Sat, 20 Dec 2008 22:47:56 +0000 Jake Walter http://icestories.exploratorium.edu/dispatches/?p=1383 ABOARD AN LC-130 EN ROUTE TO CHRISTCHURCH, NEW ZEALAND– It’s with a heavy heart that I climb aboard “Ivan the Terra” bus to get transported to Willy Field and off the Antarctic continent. As the bus pulls onto the sea ice and we continue onto the runway, I catch myself looking back and stealing glimpses of the smoking summit of Erebus and McMurdo Station nestled right next to it. We board an LC-130, and on the 9 hour flight I’m able to reminisce about the six and a half weeks I spent on the continent.

We arrived at the very end of October excited and enthusiastic – ready to go. The excitement really builds when you are on the flight over, until you step off the plane and you are assaulted by the frigid cold and the wind blows hard on your face. What’s more is that you dishearteningly realize you will spend at least a month living out of a tent in these conditions, working hard every day outside – more on that in a bit. It took us about two weeks to go through Happy Camper School, Crevasse Rescue Training, Snowmachine training, and to get all our gear in proper order.

We embarked from McMurdo in a Hercules LC-130 to Siple Dome. Because Siple Dome is far enough off-base, the pilots do not turn off the engines and they perform a cargo drop, as you can see in this clip.

From Siple Dome, we flew on the Basler, which is a DC-3 aircraft that was originally built in the 1940’s. Luckily for us, it has had some significant upgrades since then, i.e. avionics, new engines, etc. Have a look at this video of the Basler leaving us at our camp.

If All Goes According to Plan… http://icestories.exploratorium.edu/dispatches/if-all-goes-according-to-plan/ http://icestories.exploratorium.edu/dispatches/if-all-goes-according-to-plan/#comments Wed, 26 Nov 2008 19:54:59 +0000 Zoe Courville http://icestories.exploratorium.edu/dispatches/?p=1169 November 19, 2008

SOUTH POLE STATION, ANTARCTICA– The Basler plane we’ve been waiting for finally came, from McMurdo, and we were able to load it up and send it off to Camp Winter with cargo. The six of our team members out there will have something to do for the next few days at least, as we sent them the tent that will serve as the garage space for fixing and modifying the vehicles.


Tom and the Basler plane, which has landed in an ice fog.

With any luck — knock on wood, cross your fingers, whatever it takes — we will do one more flight of cargo tomorrow, and then Tom, Lou and I will head out as well in the afternoon. We’ve been working hard here getting everything ready, and are looking forward to joining the others. If all goes according to plan (but really, when does that ever happen), we will have enough room and weight to bring a few treats for the guys that have been out at Camp Winter while we’ve been living the high life at the Pole. We’re hoping the TV can go along, and some food. They’ve been living off of dried food and last year’s frozen left-overs for the last few days.


The Basler, landing in an ice fog.

At this point, after being here at the South Pole long enough, the apprehension I had about what I was getting myself into has passed, and I’m mostly just ready to get to work on the science part of the trip. It’s really not that bad working outside when it is so cold out, and it is no problem to take a break should some body part or another get too cold. Today, for instance, I was working outside strapping cargo onto a pallet in my running shoes since I had been too lazy to put my boots on this morning when I went to breakfast. It was -43 deg outside. After a bit of that, my toes were getting cold, so I just told Lou I needed to run and get my boots. Her fingers were cold in her gloves, so we both took a little break to put on the right kind of clothing. The cargo can wait.


They fit! We had been a little concerned the large doorframes for the tent wouldn’t fit through the Basler door. Of course John had long ago figured out they had…he is well acquainted with planes. We even had the heavy shop on notice in case we were going to have to cut them to get them into the plane.

The guys out at Camp Winter have two of the four vehicles started, and all of the heaters in the modules started. The floor heating system is working, the water melter is working, everything is as ready as it can be. I was joking that we should show up tomorrow carrying lawn chairs and drinks with little paper umbrellas in them, since they have had to do so much of the hard work. Instead, we’re going to bring them some cookies from the wonderful galley and dining room staff, and chip in to help as much as we can.

The Recon Flight and Sastrugi Problem http://icestories.exploratorium.edu/dispatches/the-recon-flight-and-sastrugi-problem/ http://icestories.exploratorium.edu/dispatches/the-recon-flight-and-sastrugi-problem/#comments Sat, 22 Nov 2008 01:47:12 +0000 Zoe Courville http://icestories.exploratorium.edu/dispatches/?p=1166 Nov 13, 2008
Temperature -40 deg F

SOUTH POLE STATION, ANTARCTICA– Phase One of our traverse from South Pole Station to the Norwegian Antarctic base, Troll, is to recover the four tracked vehicles we are using, which are currently stranded 350 km from the South Pole. Svein, Kjetil and Rune are the cracker-jack mechanics who will fix two of the vehicles, which are currently non-operational, and replace the differentials (this being the part that broke several time last season) in all of the vehicles. Lou and I are going to drill an ice core while the mechanics do the repairs. The spot where we will be working is called Camp Winter, since that is where everything spent the last season.

Last week, a reconnaissance flight over the vehicles determined that the surface out there is too rough to land for the Basler aircraft we were scheduled to take on Saturday. This is because there has been more than one main wind direction, which results in sastrugi (wavelike ridges on the surface of hard snow) oriented in different directions, and a rough landing for any plane.


Sastrugi at the South Pole.

The Basler has two skis and is heavier compared to the Twin Otter’s three skis, lighter weight, and beefier suspension. The pilot on the recon flight had done a “ski drag,” touching the surface, but not landing, to determine how bad the surface really was there. He didn’t even want to land the Twin Otter near Camp Winter, but saw a smoother area a bit further away where he planned to land, and then taxi everyone over to the vehicles. The crew on the recon flight took pictures of the vehicles, so we think that, at least from the air, things look ok, and nothing major is missing or completely buried. As Einar happily pointed out there are no “little black spots scattered all over the snow.”


The Twin Otter plane.

The plans were changed so that John, Kjetil, and Svein will fly out in a Twin Otter to set up Camp Winter with minimal gear on the first flight. Glen, Einar, and Rune will follow. The Twin Otter cannot carry as much cargo as the Basler, and so there will be 3 more Basler flights as soon as they can make a skiway (a snow runway) for the Basler. The South Pole has a clean air zone, which happens to lie directly in the path between the South Pole and our vehicles, and so the Twin Otter, an unpressurized plane, had to fly “over” the clean air zone, at an altitude of 30,000 ft. This means that the passengers have to fly with oxygen masks.

At Camp Winter, the plan is to open up the workshop module (all the doors have been screwed shut to prevent them from blowing off and to keep snow from blowing in) and start heating it right away using a generator for power. The next task is to get one of the vehicles running so that they can groom a skiway for the Basler aircraft to land on, bringing the rest of our cargo out to Camp Winter. Making the skiway flat enough for a plane to land on means that the group out at Camp Winter will have to knock down the same large sastrugi (snow dunes that form into the wind) that the pilot had a hard time landing on. Sastrugi tend to be very hard, as they are made from windpacked snow. The plan for now is to use the blade on Jack to knock over the tops of the sastrugi, then improvise some sort of grater using materials out at Camp Winter…2 x 4’s, the decking for the modules, or chain. In a few minutes, Lou, John, Rune, and Kjetil, who all have experience grooming skiways, were able to come up with several options using materials out at camp.

Just to set the scene for what these guys are doing…they are flying from the South Pole, already in the middle of nowhere, but at least the middle of nowhere with 240 other people, and a galley staff dishing out warm, hot meals, an extremely large, warm station, wireless internet access in our tents (our tents!) in Summer Camp, running water, telephones, a game room, a gymnasium and weight room, lounges and big screen TVs, a pool table, and 3 to 4 daily flights coming in to diminish the sense of isolation. They are leaving to go 350 km from here, to four vehicles that have been left on the ice sheet for the entire winter. We have the recon flight pictures showing that nothing has blown away, and that nothing is completely buried. But we don’t know if the seals on the doors have held, or if the windscreens on the vehicles have broken and everything is filled with snow. We don’t know if the vehicles will start or if the heaters on the modules will fire up.


The Jamesway tents in Summer Camp where I’m staying while at the South Pole.

John has considered all these scenarios, and we have multiple plans for the multitude of things that can happen. We are sending the first group in with medical supplies (including a Gomow bag, oxygen tank, and meds to deal with altitude sickness, the most likely major thing that would go wrong), several generators, fuel, emergency shelters, clothing, some water, and a minimal set of tools. That’s it!

The mood leading up to the flight is one of relaxed confidence that everything is going to work out just fine. I think this is part of the Norwegian character. All of our meetings and discussion have an element of humor (except the safety meeting we had in McMurdo…that was all business). Today, handing out the emergency communication devices to use in case of a plane crash–an Iridium phone, a PLB (personal location beacon) and radio–Kjetil jokingly gave Svein the PLB since it “only has one button to push.”


Glen, Einar and Rune wait for the second Twin Otter flight to load while Tom offers his support, and a few jokes to ease the tension.
