Another year on the Ice ...

An update from Amundsen-Scott station at the South Pole.

Unfortunately, we will not have a full recovery of the SuperTIGER payload this season.

A huge difficulty in working in Antarctica is that all scientific and support projects are subject to the weather. One major slip can lead to a domino effect that causes disruption throughout the program. Coupled with that, a primary goal towards the end of the summer season is that everyone is removed from their field-camps before the onset of winter, this of course must take priority over everything. So resources become stretched, priorities shift and schedules and plans can evaporate over night.

The SuperTIGER recovery fell victim to a chain of events that started over a week ago. Due to warmer temperatures, the ice-runway at Pegasus (which is the primary runway when the sea-ice breaks up around McMurdo station) became unsuitable for the larger non-ski aircraft used to take passengers  and supplies to and from Christchurch (i.e. the C-17, the Australian Airbus A319). When I say unsuitable, what I mean is that the runway surface melted and became too soft for these aircraft to land safely. When that happens (like last season in fact), all of the inter-continental flight duties (along with all their original Antarctic support duties) fall to the LC-130 ski aircraft and the Air Guard. There were even less of these aircraft available this season due to the government shutdown, plus one of the primary and critical roles these aircraft play is in delivering fuel to the very station I am sitting in. That fuel is the life-blood of the Amundsen-Scott station during its winter months, hence it is vital that it is fully stocked with fuel before the summer season ends.

Now, for SuperTIGER we needed two LC-130 flights to successfully achieve our goal. Due to the remote location of the payload, we needed to have a fuel cache waiting to allow refueling of the recovery aircraft that would be transporting the deconstructed SuperTIGER. Once the fuel cache was parachuted in by the LC-130, then the groom-team would arrive to prepare a ski-way for allowing loaded aircraft to land and takeoff (remember?). Then, once they had set up camp, the science recovery team (i.e. us)  would land and begin our work in earnest.

The first domino to fall was the re-assignment of the LC-130 flights to taking passengers to and from Antarctica, already stretching the ability of the program to deliver fuel, remove camps etc. So our fuel cache mission was just not to be.

No fuel cache, no groom team, no planes to take SuperTIGER back to the SLW camp (for the second LC-130 flight to bring it to McMurdo, obviously redundant now) and so no recovery. Dominoes!

What we were offered instead was 1-3 Twin-Otter flights (the small fixed wing aircraft run by Ken Borek Air or KBA) to the payload, staged from the South Pole. Each flight would allow about 2-3 hours on the ground which is just not enough time to a) dig out the payload which is without doubt heavily drifted-in by a year of Antarctic weather and b) safely and carefully remove our sensitive and expensive scientific equipment.

However, you take what you can get down here, and so what we will do is survey and assess the state of the instrument, remove some of the easily (relatively) accessible electronics and communication equipment used by the NASA Columbia Scientific Balloon Facility (the facility that manages the balloons, launch, monitoring etc.) and then strap things down as best we can for another Antarctic winter. Oh, and rescue our SuperTIGER mascot "El Super Tigre".

Uh ... guys? Little help?

However, not to worry, I will keep updating this blog for the remainder of our season down here. I hope to be on the second Twin-Otter flight to the payload (the first is a reconnaissance mission where Thomas Hams is the only science representative) and will share my experiences on that exciting trip (weather permitting of course!).

Furthermore, expect a few more updates on life at the South Pole. Touching BOTH South Poles (eh?), touring the tunnels under the station in -55C/-67F temperatures, getting to visit the nerve-center of the $300 million dollar Ice-Cube experiment and last but not least, watching Top Gun on VHS on movie night (as exciting as the previously mentioned? ... possibly).

Onwards to the Pole

After a few days of finalizing our gear, we are ready to go.

If all goes to plan, this evening the SuperTIGER recovery team will be sitting in Amundsen-Scott station at the South Pole. Internet connectivity will be limited there, but I certainly hope to update the blog in some capacity over the coming days. I also hope I won't be suffering the ill effects of being at altitude!

In Christchurch, we were issued "Diamox" (Acetazolamide) tablets which we are supposed to start taking the day before leaving for the Pole, these pills are expected to reduce the probability of getting Acute Mountain Sickness. The South Pole is at an elevation of 9,300 feet (2835 meters) but feels like 11,000 (3350 meters), this can go up to 12, 500 ft (3810 meters) with a low pressure system. The idea being that Barometric pressure decreases at higher latitudes. Flying from McMurdo which is at sea level to those effective altitudes within a 3-hour LC-130 flight will be quite a change to the system, so we need to take things easy upon our arrival. The diamox tablets don't taste the best and can have side effects of making carbonated drinks taste flat (not a killer) and of being a diuretic (more annoying than anything). I noticed fairly quickly after my first pill that I was getting very thirsty, so I've been drinking water steadily since yesterday.

Not Coca-Cola friendly.
In the meantime, life in McMurdo carries on. I've been catching up with old friends from last season and making new friends for this one. Coming back has been interesting because you see quite a few familiar faces but a large amount of new, things are familiar but you can still meet other interesting and fresh characters. I have spent a few nights in one of my favorite places in McMurdo station called the Coffee House. It is one of the original buildings from back in the days when the US Navy ran McMurdo, the building was previously the Officers club. Last season, the Coffee House only sold one thing ... coffee (however you could bring your own alcohol there if you wished). This season however you can now buy bottles of white and red wine if you're feeling classy. The place is a perfect spot for a relaxed night where you can catch up with people, write post-cards or work and sometimes there will be a live music session in the corner (which is really excellent).

The Coffee House.

Otherwise in my free time (which has been limited with all the prep work), I finally got to take a stroll over to another one of my favorite spots in McMurdo, Hut Point. Here is where you will find a shelter (Discovery Hut) built by Robert Falcon Scott way back in 1902. Last year I had the pleasure of getting to tour the inside of the building, still filled with supplies and clothing from the previous occupants on Scott's expedition. This season the hut is undergoing a preservation scheme to mitigate the effects of over a century of Antarctic weather. This undertaking is managed by the Antarctic Heritage trust, a non-profit operation which aims to protect several historic Antarctic sites. It didn't make for the prettiest of pictures, but preserving the history of those first intrepid explorers for future generations is undoubtedly worth it.



Discovery Hut and the preservation plans.
I carried on past Discovery Hut to get a look at the ice-shelf, you can see that it is breaking up nicely. Didn't happen to see any penguins or seals on this trip, but I hope to get out this direction again soon.

One fairly surreal thing that I saw on my walk to Hut Point was a softball tournament that was taking place at the cargo-staging area by the Ice Pier. This tournament started at 11am and went on until 5pm, the field was complete with bleachers, sausages and beer. I don't think I've ever seen such a heavily dressed group of softball players in my life. Unfortunately with just four SuperTIGER team members (including two Europeans who are more used to kicking things with their feet), it was an unfortunate but sensible idea to not enter a team.

Anyway, the adventure continues at the South Pole.

Getting ready for the show

Since arriving at McMurdo, the SuperTIGER recovery team has been busy getting ready for heading out to the payload.

What does this involve? The answer is, a lot.

The logistics of flying people and equipment around the remotest and most inhospitable place on Earth (although that may currently be the mid-west United States) is something you don't really grasp until you sit down in meetings (scientists, NSF and McMurdo logistics etc) and flesh out all the details of your trip. Thankfully the brunt of that work was felt by Thomas and John (who had done this kind of thing before on the recovery of the BESS-Polar II payload in 2009). As the new guy, I found the organization and logistical planning around working in the "harsh continent" fascinating.

To get to the SuperTIGER payload, we need to transport ourselves (the 4-member science team) and up to 2000 lbs (910 kg) of recovery tools and camping equipment from McMurdo station to the Amundsen-Scott station at the South Pole (~ 920 miles/1480 km), then from the South Pole to the payload site (a further 540 miles/870 km) and our awaiting camp/groom team. Before all that though, you need to get fuel out to the payload site (for the planes to refuel) which means an LC-130 needs to perform a "fuel drop" near the site (parachuting a pallet of 40 fifty-gallon fuel drums to the ground successfully). Once that fuel drop is completed, then the groom team can fly out on Twin-Otter aircraft to prepare a ski-way (i.e. a runway on which heavily loaded aircraft can takeoff safely) along with the general camp. All of this involves several disciplines and departments:  fixed-wing (for aircraft), fuel, cargo and Berg Field Camp (the BFC) amongst several others. Add the famous unpredictability of Antarctic weather to the mix, and you have yourself a logistical headache. 

All you can do is plan for the worst, be flexible and don't panic (too much).

The last few days has seen the team rifling through shipping containers, compiling and organizing all our tools needed for recovering the payload (i.e. screwdrivers, drills, saws, drill-bits, rope, wire-cutters, clippers, ratchets, sockets, hammers, ice-pick, shovels and so on). You can be sure there won't be a Lowe's nearby if someone forgot to pack a 1/4" combi-wrench.

Some of the recovery items needed were actually being kept at the NASA Long Duration Balloon (LDB) facility out at Willy Field (about 6 miles/9.6 km away from McMurdo station). Unfortunately due to the government shutdown last year, the entire ballooning season was cancelled (resulting in the cancellation of two scientific-payload launches and one NASA test balloon launch, just one of the many scientific casualties resulting from the shutdown here in Antarctica). This meant the facility was never really prepped for the summer season.

Due to the warm weather here in McMurdo, the roads out to LDB and the Pegasus airfield are in very poor condition, hence all wheeled vehicles are banned from traveling on the road (except for the Deltas and Ivan the "terra" bus shuttling people to and from Pegasus). However, we needed to grab our stuff, so we were kindly helped by our local National Science Foundation representative Brian Johnson who provided transportation to LDB in the form of a tracked "Pisten Bully". These tracked vehicles can seat six (without any gear in the cab) quite comfortably and truck along at about 8 mph!

Tuesday morning at 830am, Brian started all four of us on the road to LDB.

John, Brian Johnson and Grant ready to roll.
It was going to be nice to be heading out the LDB facility again, without doubt my favorite commute in the world. This time however, I wouldn't be riding the warm and (relatively) comfortable Ivan the "terra" bus but this motorized box on tracks.

A box.
A box with a seriously beautiful view though.
Once we arrived at an eerily deserted LDB facility, we entered into one of the payload buildings (where we had been told our things were left) and loaded up the Pisten Bully. As this only took about 10 minutes we decided to have a walk about and take some pictures.

The way out to the launch pad. Usually there is a road-way here, another casualty of the shutdown.

Brian was very kind and acted as our personal photographer while we made suitably grandiose poses in front of Mt Erebus and the surrounding area. It was definitely chillier out at LDB than at McMurdo so our modelling session was cut short for the warmer confines of the Pisten Bully cab.

Getting chillier.
On our way back, packed in and surrounded by our tools and cold-weather gear (with my lower back receiving a thorough and unwanted massage from the Pisten Bully trundling over the snow and ice) we had one of those special encounters unique to Antarctica. An Emperor penguin was spotted (Grant had seen him the previous evening at Happy Camper school in this area). It is not unusual to see Emperor penguins alone in a remote area, where they molt in peace. This one was hanging out about 30 meters from the road. We stopped and from a distance took some photos so as not to disturb him unduly. Personally, I thought he looked fairly miserable (although in fairness, I'm no penguin psychology expert).

Miserable? You decide!
 Last year when I left McMurdo, I finally saw an Emperor (also molting and solo) at Pegasus airfield. I never really expected to see another (except at a zoo maybe) so it was an affirmation for me that you just can't tell where you may end up again in the future.

Catching my breath

It has been a whirlwind week since I left St. Louis for Antarctica.

St. Louis to LA, LA to Sydney, Sydney to Christchurch, Christchurch to McMurdo station. Planes, trains and automobiles. Moving from winter in the US to summer in New Zealand, crossing from the northern hemisphere to the southern, 3 continents, many airport coffees and lots of music. Never living the 31st of December (I crossed the dateline on my flight from LA to Sydney) I managed to "celebrate" New Year's eve by texting with my family back in Ireland on my 8 hour layover in Sydney airport (the benefit of being ahead a day). Arriving in Christchurch at 2am, taking the same shuttle service like my previous trip to the same hotel again, I was almost expecting to get the exact same room to really make things surreal.

I rendezvoused with Thomas, John and Grant the following morning and since our flight to McMurdo on January 3rd was cancelled due to poor weather in Christchurch (high winds) we used the opportunity to visit Arthur's pass (about a 2.5 hour drive away). I never went to the New Zealand countryside on my previous trip and I can say I certainly wasn't disappointed. John Mitchell drove us through the stunning Southern Alps where we stopped now and then to sample the sights and sounds of the New Zealand outdoors. Sacred Maori caves, limestone outcrops like castles, from beautiful sunshine to torrential rainfall and spectacular waterfalls ... along with lots and lots of sheep. I soaked it all in as much as I could with my jet-lag nagging at me to sleep, because I knew that this was not an opportunity that comes often.

Castle Hill.


Waterfall in Arthur's Pass.
Once we returned from our day-trip it was time to get re-packed and ready for the flight to McMurdo. We were leaving the hotel at 630am for check-in at the US Antarctic Program (USAP) center, so I can't claim I got a nice lie in. Acting on semi auto-pilot, next thing I know I am waiting in the "departure" lounge watching NBA basketball (on the US armed forces network no less) along with several introduction videos to life in Antarctica (take home message: don't harass the penguins).

The waiting room ... sports provided free of charge.
Next thing, we're sent through a security check before being bussed out to the waiting LC-130 transport. I try and get a good look at the greenery around the airport on the way, it'll be over a month before I see a tree again. We took a photo before boarding the plane, looking fresh-faced and full of energy. It will be interesting to see how we look after one month on the harsh continent ...

The LC-130 flight to McMurdo station take over 8 hours. Things are loud enough that you need to wear ear-protection constantly, so conversation is limited to say the least. I read, slept, listened to music and ate our provided lunch (sandwiches, crisps, bars and an apple). I was surprised at how fast the time passed and before I knew it I saw people begin to stir and excitedly look out the windows and photograph. I knew what this meant ... Antarctica was in sight. I looked out my nearest window and saw we were coming in over the Ross ice shelf (which had started to break up), that feeling of visiting an alien world had returned again. I was really coming back.

Back to the Ice!

Hello all,

My name is Dr. John E Ward, I am a Research Scientist at Washington University in St. Louis. Last year, I spent 96 days in McMurdo station working with the SuperTIGER balloon-borne payload.

After SuperTIGER's extremely successful (and long) flight during the 2012/2013 Antarctic summer season. It came to rest via parachute on February 1st 2013 at the following coordinates:

82°14.80’ S, 81°54.72’ W

Otherwise known as "the middle of nowhere".
The middle of nowhere.
It being so late in the season, with personnel and camps being removed from the field, there were no resources available to mount a recovery of the payload. Hence, SuperTIGER was left at that location until a full recovery could be attempted the following year. Well, that time has come!

Last year Ryan Murphy, our graduate student working on SuperTIGER at WashU, did a fantastic job updating this blog with the day-to-day happenings of life at McMurdo station. I am also going to try and share my thoughts and experiences from my second trip to "the ice" as one member of the SuperTIGER recovery team.

The science members of the recovery team consist of Dr. John W. Mitchell and Dr. Thomas Hams from NASA's Goddard Space Flight Center and Grant Mitchell, a technician from the University of Maryland, Baltimore County along with yours truly. Furthermore, we will be supported in the field by three survival experts/mountaineers/camp managers/superheroes called Scott, Lance and Bill (the "groom" team).

Our route to the payload will consist of an LC-130 flight to the South Pole (Amundsen-Scott base) where we stay the night before taking a Twin-Otter flight to the SuperTIGER payload. Next, we will spend up to 10 days (depending on weather and travel etc) camping by the payload, deconstructing it and preparing it for removal from the field. The return trip will bring us and the payload back to McMurdo station via the Subglacial Lake Whillans camp. Once in McMurdo, we pack the SuperTIGER detectors into a shipping container for shipment back to the United States ... simple!

Yesterday, the science team arrived in McMurdo station without any major disasters. The weather is a balmy 35F (2C) and spirits are good. Since I'm still getting settled, it will take me a few days to get into full "blogger" mode ... but please stay tuned! I plan on updating people on our flight down and the first few days getting acclimatized again to life at McMurdo station, Antarctica.

Termination: February 1 (& 2), 2013

Friday morning I woke up early from jet lag, and just when I was about to fall asleep I got a call that we'd gotten word that we would be coming down soon. We turned off our instrument and prepared for cutdown. Since the concern was the poor terrain to the south, we got a few extra hours of flight when our trajectory turned north, and we sent the commands to turn the instrument back on.

Just as I was leaving to go stop by the department and say hi to people and go to our Graduate Student Seminar talk, we got another flurry of emails to turn off the instrument. This time, we ended up starting to come down about 45 minutes later.

The process of termination is pretty cool--helium gets vented from the balloon, the balloon is ripped so it comes back down, the payload falls, and then a parachute is deployed. After we hit the ground, the parachute detaches (TIGER 2001 had some issues with this step), and the instrument is on the ground.



Super-TIGER hit the ground at 17:17 EST (22:17 GMT) on February 1, 2013. The flight time was about 55 days, 2 hours, and 32 minutes. The final resting place is at 82°14.75 S, 81°54.83 W.

I plan on updating the blog at least once more with the details of the (very unlikely) recovery operations this year, if any.

The Long Trip Back: January 30-31, 2013

I got up early Wednesday morning in McMurdo and made sure that all of my stuff was out of my room. I went over to the galley for one last breakfast, said goodbye to Sean, and then walked up to the Movement Control Center, where we were supposed to show up at 7:15am. 

Decoration in the MCC. 
Once everyone was assembled, we got on our old friend Ivan the Terra Bus for one last 7:30am trip out of McMurdo.


The Pegasus airfield is out on the permanent ice shelf south of McMurdo. For the first few miles, the road to the airfield is the same as the road to LDB, so we got one last glimpse of the LDB camp.


Once we got to the airfield, we got a good look at one of the Kenn Borek Basler aircraft. These modified DC-3s are what we hope to use to recover the Super-TIGER payload. I'm not sure where this one, which was closest, was going that day but the other had another successful flight out to BLAST, where Elio and the recovery team got everything but the aluminum frame.


We didn't go inside the passenger terminal building, so we basically waited around outside for a while and watched the goings-on of the airfield. It was a pretty nice day, so there wasn't much going on for a while.


Eventually, though, a whole group of people started walking away from the passenger terminal. We weren't sure why, until we saw that they were going to get a better look at an Emperor Penguin that was standing around next to some equipment.


We watched as the penguin lay down, then got back up again and waddled all around for a while.


Since this was the only Emperor Penguin I saw the entire time I was in Antarctica, I took a lot of photos.


The penguin started walking kind of towards us, so I got much closer than I'd expected by just standing still.


Eventually, a van showed up to shuttle us out to our plane. Just as we were getting in, a Skua, evidently sick of the penguin hogging everyone's attention, landed next to someone's carry-on bag and stuck its head in a plastic bag that they'd packed their lunch in, looking for food. Someone nearby noticed and scared the skua away, but then it decided to land on top of the van as we were loading up. Once it flew off again, we drove over to our plane.

We flew out in a New York Air National Guard LC-130 Hercules. This is a modified version of the C-130 military transport that has skis and so can land on the Pegasus skiway. The larger C-17s that just have wheels haven't returned to the ice yet. 


The LC-130 is notably a propellor plane, which means that it doesn't travel as fast as the C-17 we took down here. We were told that our flight would probably be around 8 and a half hours.


Inside, the plane was pretty full, so I only had about 2 inches between my knee and a pallet of bags brought on board by all the passengers.


We settled in for the flight, which ended up taking a little under 8 hours. I wasn't able to sleep or do much other than read.


Eventually, though, we touched down in Christchurch and they opened up the back loading hatch of the plane. It was there that I got my first glimpse of a living plant in three months, the trees around the airport.

We hopped on a bus for a quick ride over to the terminal, went through Immigration back into New Zealand, then collected our bags and went through customs. I took off all of my required ECW gear and put on regular tennis shoes, because it was nice and warm in Christchurch.

Then, I had to walk over to the Clothing Distribution Center to return all of the cold weather gear I'd been issued back in October. I pushed my luggage cart down the sidewalk all the way to the CDC, through some nice warm and sunny weather. I didn't mind that the walk was long, because I got to enjoy it.

After returning my gear and picking up my forward itinerary, I waited around for JohnE and Thomas. Thomas was staying at a hotel closer to the airport, so he just walked over. JohnE eventually showed up still wearing his wind pants and ECW boots, so he did not have nearly as pleasant of a time in the 86 Fahrenheit/30 Celsius weather.

By the time we got to the hotel--JohnE and I were at the Pavillions again--it was 7:30pm. After showering and checking email, we went over to the pizza place we'd gone to the first night in Christchurch back in October and I once again had a delicious lamb and veggie pizza with rosemary mint sauce. We also stopped by Smash Palace, the bar near the hotel with scaffolding and plastic sheeting for walls.

Our taxi to the airport left the hotel at 5:15am Thursday morning, so I didn't get a chance to get too much sleep (JohnE and I were still used to our night shift). The internet had been out at the hotel after we got back Wednesday night, so I hadn't seen an email telling me that I was now flying through Dallas/Fort Worth instead of LAX. This lead to me getting very confused when I checked in and was told that I'd have to collect my bags in Dallas to go through customs.

The flight over to Sydney wasn't too bad. We had a 6-hour layover there before continuing on to Dallas, and it was there that we said goodbye to Thomas, who left on an earlier flight through LAX.

We got on the plane to Dallas and were greeted with an announcement telling us that not only was the seatbelt sign off, but we all had to actually keep our seatbelts UNfastened for the next several minutes while the plane was refueling. After a safety video by Ricky Ponting and other members of the Australian cricket team, our 15-hour flight got underway. Among the many movies I watched was a documentary about Felix Baumgartner, who jumped out of a high-altitude balloon at 127,000ft in October. Looking at the view from that altitude was pretty amazing, and I got a good sense for just how high up Super-TIGER has been flying.

After a short layover in Dallas, we made it back to St. Louis Thursday evening, and I went out to meet up with a few friends that night (also, my apartment was at about 52 degrees when I got home, so I didn't mind being out while it warmed up a bit).
