SEAT: Satellite Era Accumulation Traverse: Waiting Again

December 8th, 2011 by Maria-Jose Viñas

By Lora Koenig

It’s Thursday, December 1, and I am, yet again, sitting in our office, waiting.  As the saying goes, “hurry up and wait”: This rings true in Antarctica. Last week, we were waiting for our radars to arrive on a plane from Christchurch. Usually there are about three flights a week from Christchurch to McMurdo, but an entire week of flights was canceled due to bad weather here. And finally, a plane arrived on Monday, November 28, bringing fresh fruit, new people and, most importantly, our radars.

Ludo and Clem quickly set up the two radars, ran a few tests to make sure they were working and repacked them for shipping to Byrd Camp. Normally we would take a few days to do this but, since we were delayed, we all worked hard and completed the tasks in a few hours. We repacked the equipment very carefully to prevent damage, and put it into the cargo system. (See Michelle’s blog post to learn more about the cargo system). Our intracontinential cargo needed to be in the system 48 hours in advance, and we were hoping to fly to Byrd on December 1 (that is, today).

Clem and Ludo testing the radars. The coil of wire, in the center of the picture, is a delay line that sends the radar signal through a wire that attenuates the wave. Delay lines are a good way to test the radar when the antennas are not yet hooked up.Clem and Ludo watching the radar echogram to make sure the radars were not damaged in shipping. Clem is holding a set of notes: We always have good documentation of our procedures to make sure we take consistent measurements. The notes also help us in case we forget anything.

Just as a reminder here is the location we are trying to get to.

So our estimated departure date has come and gone, and here we are still in McMurdo. This is not a big surprise; delays are common in such a harsh environment. We are now scheduled to go to Byrd on Monday December 5. All of our work in McMurdo is done, so we will use the delay to rest a bit before the hard work of the traverse begins.

Michelle and I took advantage of the nice weather to go skiing on the McMurdo Ice Shelf, which is connected to sea ice. In a few weeks, people will not be able to ski here anymore because the warm summer temperatures from both the air above and the water underneath the shelf will thin the ice.

Why are we delayed? First, as I mentioned, McMurdo had a week of bad weather and no planes could land or take off.  And once the weather in McMurdo cleared, it was Byrd’s turn to have bad weather, so planes could not land there. On top of that, there is a lot of science going on at Byrd this season, including another traverse lead by a NASA colleague, Bob Bindschadler, headed to Pine Island Glacier. (Check out this video on the Pine Island project, or visit their website.) Because there are so many teams flying to Byrd, we have to wait for five flights to get in before we are assigned a plane load for our science gear, fuel, snowmobiles and ice core boxes. Our team has a full LC-130 plane load of gear that needs to make it to Byrd.

Yesterday, they were finally able to get some flights into Byrd. Our flight number is T012; flight T010 will take off for Byrd this evening, then T011 has to fly and then it’s us. We are watching the monitors in McMurdo that show the flight status, just like at the airports, hoping that flights get in. We cheer when a flight returns and groan when a flight is canceled due to weather.

There is one more issue that is causing delays.  This week they are moving the runways at McMurdo. In the early season, when it is still cold, the planes land very close to McMurdo on the sea ice at a place called Icey Runway. As temperatures warm, sea ice thins and the runway is moved farther inland to Williams Field, where the ice is thicker. This weekend is when they move airports, so there are no flights scheduled for Friday or Saturday (normally, there would be flights Monday through Saturday). So we will have another weekend in McMurdo, and when it’s time to fly to Byrd we’ll do it from William’s Field, about a 45-minute drive from McMurdo.

While we were waiting, I finally took some pictures of Percy the Penguin. Percy was given to me by a friend; it came from a geocache site in Seattle, WA and has now made it to Antarctica. Percy is actually the only penguin we have seen here. So far, the only wildlife we have encountered are skuas, large seagull-like birds, and Weddell seals that lounge on the sea ice just outside of McMurdo and Scott base.  Through there are no seals in the picture of Michelle skiing, she is on an ice shelf below which the seals could be swimming. When the seals find a hole in the ice they come up onto the sea ice or ice shelf and lounge in the sun.

SEAT: Satellite Era Accumulation Traverse: Happy Sunday Around McMurdo

December 6th, 2011 by Maria-Jose Viñas

By Clement Miege

Hello everybody! This is Clement, for my first blog post! Sunday, November 27 was our day off, so we went exploring the surroundings of McMurdo Station. At around noon, Michelle and Lora decided to go cross-country skiing on sea ice while Jessica and Randy went to Scott Base for some shopping at the Kiwi store, which is stocked with lots of Antarctic T-shirts and other souvenirs.

On our side, Ludo and I took advantage of the wonderful weather and hiked the Castle Rock loop. I hiked this trail last year and it is by far my favorite walk near the station. We started at the fire house at around 11:30 AM. Because the trail is pretty long (9.8 miles), we were required to take a radio with us and give our estimated return time and the contact info for our point of contact in town to the responder on duty at the firehouse.

The walk toward the summit of Castle Rock is very pretty, with amazing views everywhere: behind us, we had Mount Discovery and the Royal Society Mountain Range. In front of us, we had incredible scenery with Castle Rock in front of Mount Erebus and Mount Terror. While approaching Castle Rock, we were able to enjoy a nice scramble leading us to the summit, with fixed ropes set for safety on the ascent. After a quick break at the summit, where it was really windy, we decided to head back down.

Here is our hike in pictures so you can enjoy it as well.

One of the three “apples” that you can find along the Castle Rock loop —a warm emergency shelter and a good spot for resting safe from the wind.

Ludo and I: Happy faces at the Castle Rock summit!

Open water, and huge tabular icebergs. The ocean is not far from town — in January, an icebreaker will open a path to get to McMurdo and resupply the station.

Ludo, following the flag line on his sled!

It took us about 4 hours to walk/slide through the whole loop. In fact, we cheated a little bit, taking advantage of the last shuttle to go back to McMurdo station from Scott Base, which knocked off about 2 miles. It was a wonderful trip; it was good to be outside while the weather was nice!

But that wasn’t the end of our day! After dinner, Jessica, Randy, Ludo and I went with a small group to Pegasus runway, an airfield near Mc Murdo station, to visit the remnants of a plane that crashed in 1970 and got stuck in the ice. It took us an hour to get there, travelling in a Delta. After spending a little time checking out the plane, we got back to the station at around 8:30 PM, ready to go to bed after a long day of adventures outside.

Jessica, Ludo, Randy and I are standing on the tail of Pegasus. It was the first time that I got to walk on top of a plane, pretty cool!

Pegasus, with visitors.

Here are some bits of info that I was able to collect on this crash, where fortunately nobody died. The plane, a C-121J named Pegasus, took off from Christchurch, New Zealand in October 1970. The flight to McMurdo went well until a storm started developing near the runway. Unfortunately, the flight had already passed the point of safe return, which meant that it did not have enough fuel to make it back to Christchurch. The only choice remaining was trying to land with no visibility. After a long time circling above the runway to get a little bit of visual information, the pilots attempted to land and the plane slid into a heavy snowdrift deposed by the storm, spun and broke its entire right wing and finally stopped. Luckily, nobody died in this accident.

If you would like to get more information on this story, follow this link.

Now this site is becoming a touristic attraction but it still shows a part of the Antarctic history. After this dramatic event, more precautions have been taken to allow planes to boomerang back to Christchurch if they run into bad weather.

SEAT: Satellite Era Accumulation Traverse: Field logistics

It has been a busy first week in Antarctica! We planned to stay 10 days at McMurdo station so that we could complete all of our required safety training and prepare all of our food, shelter, and equipment for the traverse. There are many people in McMurdo who support our field research and we thank them for all of their hard work in helping us make our field season a success: They assist us in getting all of our food and camping gear, coordinating flights to Byrd Camp, and sending all of our cargo (and our team!) to Byrd. 

Here’s a summary of everything we did this week:

We spent one day testing our tents, sleeping bags, and kitchen supplies, and then we packed it all into duffel bags and boxes that we will be able to load onto the sleds that we will tow behind our snow machines. There are so many small things (like lighters, flags to mark our camp, insulated water bottle holders, batteries and much more) that we must remember to pack, but I’m glad to say that we have put all of this together now!

The gear we're borrowing from McMurdo was waiting on these shelves when we arrived at the station.

 

Brian and Ludo prepare the boxes for shipping by tightly strapping them with a metal bander.

We spent a few days going through safety training — anyone new to Antarctica went on a two-day overnight trip to learn how to be comfortable and safe in the harsh Antarctic environment, and those of us returning to Antarctica took an afternoon refresher course.

We had other meetings to arrange our communications with McMurdo Station when we are out on our self-supported traverse. We must call in every day: if we were to miss a call (we won’t!), a search and rescue team would be deployed within an hour, and everyone would be on alert. 

We also checked our equipment that had arrived to the station so that we know it will work in the field.  And, most importantly, we picked up our food — including over 200 chocolate bars! 

One of our boxes of food. On the traverse we will carry three of them (two filled with dry food and one with frozen food.)The ice-core drill and other necessary equipment for drilling the ice cores are packed in these boxes.

 Today we completed snow mobile training, so we now know how to ride and fix the machines once we are out on the traverse. We are almost all ready to go now and we hope that the weather will be good the next few days so that we can fly to Byrd Camp soon.

SEAT: Satellite Era Accumulation Traverse: Still Waiting

December 5th, 2011 by Maria-Jose Viñas

It is Sunday night, November 27, and I am sitting in our McMurdo office with Michelle. We had a great Thanksgiving weekend. Here on the Ice we celebrated Thanksgiving on Saturday, November 26, instead of on November 24 (the day it was celebrated in the United States). The reason for this is that people in McMurdo work 6 days a week (Monday through Saturday) so when there is a holiday, it is always celebrated on Saturdays to get a full weekend off.
 
On Friday evening Randy, Clem, Ludo and Jessica toured Discovery Hut. Saturday, our Thanksgiving Day, started with the entire team running in the McMurdo Station Turkey Trot, a 5K race over to Scott Base and back.  It was Jessica’s first 5K race ever and she can now say that she ran her first 5K in Antarctica, which I imagine is quite a unique story.

The day concluded with a very nice dinner that included all of the traditional Thanksgiving fare along with handmade truffles.

Michelle and Clem, all dressed up for Thanksgiving dinner.

There was one thing noticeably missing at Thanksgiving dinner, and that was “freshies.” Freshies are how people on the Ice call fresh vegetables. There were no freshies because no plane has arrived McMurdo since November 21. This means there has been no resupply of vegetables, no new people, and no incoming cargo. 

Randy’s plate, full of turkey, stuffing and rolls... but no "freshies".

Having plane delays due to weather  is common and expected in McMurdo. Normally, this would have little effect on us, besides the occasional craving for a green salad, but this year is worse, because the shipping contractor made a mistake. All of the radars that we shipped from Kansas were supposed to be here when we arrived, but they were not.

During our time in McMurdo, we have to complete the following tasks as quickly as possible so we can get on a plane to the field:

1) Find our science equipment and traverse equipment

2) Test all of our equipment to make sure it works.

 3) Put all said equipment in the cargo system to get shipped to Byrd and

4) Complete all training and safety classes (See Ludo’s post).

Once these steps are completed, we can schedule our flight to Byrd. We had planned to leave for Byrd on November 30, and we have completed all of our tasks (except for one additional field safety training on Monday, November 28,  and a snowmobile training on Tuesday, November 29.) But we cannot leave McMurdo until we get the radars: They are essential to our science. So for now we are sitting and hoping that the next plane that arrives to McMurdo will carry our radars. If delays continue, we’ll have to switch to plan B (or C, or D). 

Right now, Plan B is that Clemont may have to stay behind to receive the radars while the rest of the team goes ahead to Byrd camp. But hopefully, the radars will arrive before our plane leaves for Byrd Camp. As soon as the radars arrive, we will test them to make sure nothing broke during shipping, since it is easier to fix things in McMurdo than while in the field. Then we will pack them again for the trip to Byrd. 

The weather forecast for Monday doesn’t look great, but here’s hoping we get our radars soon. If you want to follow the weather forecast for McMurdo check out  this website or you can virtually look out the window like we do, through the McMurdo webcam.

SEAT: Satellite Era Accumulation Traverse: Happy Camper School

December 2nd, 2011 by Maria-Jose Viñas

By Ludovic Brucker

Jessica, Randy, and I were scheduled to attend a 2-day Field Safety Training Program (a.k.a. Happy Camper survival school the nickname makes it sound much more fun than its official title!) on Tuesday and Wednesday, 23-24 November. The training includes spending a night outdoors. I heard about the program months ago and I was definitively looking forward to this enjoyable and educational experience. The invitation read: “Be sure to show up the morning of your course dressed for the field in your Extreme Cold Weather (ECW) clothing.  […] Trust us!  We want you to be comfortable and safe for the Antarctic environment.” Sweet!

Our group on our way to the Happy Camper site, near Mt Erebus (on the left, 3794 m, or 12,448 ft, high).

On Monday evening (Nov. 22), I had carefully prepared my ECW++ pack (the ++ stands for water and food). My ECW gear consisted of: socks, bottom and top thermal base- and mid-layers, a fleece jacket, a thick bib, Big Red, boots, and all the basics (such as hat, gloves and glove liners, mittens, face protection, etc). Additionally, we took the sleep kits and tents that we will be using during our traverse. These last two are very similar to the ones you most probably use when camping, but the sleeping bag is much thicker and we also use pads, a fleece liner, warm fleece pants, and a pee-bottle. Our bag also contained other basic and mandatory items, such as sunglasses, goggles, sunscreen, lipstick, and water bottles, among other things.

The first morning of the training was dedicated to listening to lectures about the harsh Antarctic environment and its rapidly changing weather conditions, with focused courses on topics such as how to deal with hypothermia, etc. We then headed out to the field a few miles away from McMurdo station, in the vicinity of Mt. Erebus. It was gorgeous! We were a total of 20 people, all freshly arrived from New Zealand the day before.

The outdoor session was much cooler (pardon the easy pun) than the lectures and it provided us with information on setting up camps, such as mounting a mountain tent and a Scott pyramid tent. The latter is particularly well suited to Antarctic conditions and it’s inspired in the tent Robert Scott designed for his 1910-13 South Pole expedition. It resists high wind speeds very well; we will have one in our traverse. Obviously, the tent resistance to wind is all about the quality of its snow anchors.

Instead of spending the night in a tent, I opted for the alternative, which was digging up a trench and sleeping in it. “Why not,” I thought. “I’d rather experience my first night in an Antarctic trench when the weather is pleasant and I have resources close by than when I have no alternative to using a trench.”

A general view of our Happy Camper site with yellow Scott tents (right), classic mountaineering tents behind a wall made of snow bricks that protects the tents from the wind, and trenches (front).

My trench had a narrow opening and got wider a few feet deeper. The ceiling was made of snow bricks covered by lighter snow to close joints and holes. I used my bag as an horizontal ceiling door, right above my head. An easier option would have been using a sled for the ceiling, as others did.

A view of my trench. It is narrow at the top and wider at the bottom. Being 6 feet 3 inches tall meant I had to dig a long trench.

My night was perfect: cozy and unbelievably quiet! I didn’t even notice that the wind had started to blow strongly during the night. I woke up around 4 AM feeling a bit chilly; I ate a chocolate bar, drank some water, and went back to sleep. It was interesting to wake up in the middle of the night and be able to see like if it was day time. At this time of the year in Antarctica, all nights are bright, with only one star in the sky. It felt weird to be sleeping in a snow trench only three weeks after having slept in a hammock hung between palm trees in Big Island, Hawaii. Thanks Lora and Thorsten for these two experiences!

Happy Camper also taught us how to use a High Frequency radio. It is significantly different to use from the common very high frequency radio. After deploying the two 10-meter antennas, we made calls to South Pole station (1360 km, or 850 miles, south of us.)

In summary, these first two days outdoors were successful. However, we expect tougher conditions once we’re out in the field, in the West Antarctic Ice Sheet.
