Dave Down Under - Dispatch 2 - Learning the Logistics


The latest from Dave...

A lot has happened since I wrote four days ago. It has been primarily about learning logistics and absorbing the vaunted (again, perhaps infamous) culture of McMurdo Station. To lay the foundation for some of the imagery and your imagination, you should understand this is a frontier town. Unlike most tumbleweed or tundra frontier towns, this one is inhabited half by eggheads, and half by the rough hewn "get it done" staff.

A quote regarding people who work at McMurdo: Antarctica is at the bottom of the earth, so anyone not tied down eventually gravitate down there. There is a grain of truth to this saying. There is a sense of wanderlust to many of the people here. It's a place where the reclusive people who don't fit in well in the main stream, but don't accept that they have to march to the standard drums find a temporary haven. Temporary, because few people can handle the closeness of the community for more than a few seasons. The few that do make a life out of working here seem to veer that much further off of the norm.

One of the fascinating aspects of living in such a small communities is how they interact with each other outside of work. Honestly, I can't write in-depth on this. It will require at least one more significant visit to the station. The small amount I have witnessed is the night I went out to the bar to meet Ann. Unfortunately, I didn't find her, but was able to hang out Robert, a colleague of John's came over with a friend and asked if they could join me. The wine bar is the most "civilized" of the three bars at McMurdo. It is quite dark, rather small, and only serves wine. So this guarantees that is the most heavily weighted with "beakers". There were pockets of reclusives working on their computers, and pockets of rowdiness. However, for the most part, the scene was that of lively chatting. I also hopped over to the other two bars, although much more briefly. The second bar, Southern Exposure, was stuffed with smoke and very loud. This seemed to be where the workers really let loose. After ascertaining that I knew no one there, I quickly left for the third bar. There, I found one of my roommates, and it was a non-smoking bar with pool, so I made this my last stop. This bar, Gallagher's, was a blend of the two others.

The next day, Sunday, was a day of learning for me. I finally started learning about all of the activities that happen in and around McMurdo. More often than not, I was learning them after they were options for me, but I'll know better for the next time I get to spend here. Lectures, dance lessons, volleyball teams, tours, free training of various sorts, Burger Bar, philosophy discussions… there's a lot happening here.

Sunday evening, I did manage to get out and hike up the nearby Ob Hill. I started at 8pm. This is an easy thing to do because, as you guessed, it is complete daylight. However, the wind was really whipping through. By the time I made it back down (about an hour), my face was chilled down so much that my facial muscles weren't operating properly.

Monday was another mellow day for me. John and I had a few things to take care of, but otherwise, I was working on my own stuff. Mitch, a fellow grad student and roommate was working all day on the mindless task of washing hundreds of sample bottles. After several hours of working on my computer, I spent an hour and a half assisting him and a colleague in the chore so they could be freed of the chore. This evening ended with three other grad students drinking beer and walking up Ob Hill again. This evening, the air was dead still, except for at the very top. The light was stunning, and it was warm. We didn't leave our room until 11:45pm. Full daylight.

The next morning, Tuesday the 6th, was a little painful after our late night, but we were fueled by our goofy adventure the night prior. This morning Mitch and I were due to check in at 8:30am to Happy Camper training, the basic survival course. For logistical and litigation reasons, they require that anyone doing field work outside of the station (even day trips) take the winter survival course in the event of a plane/helicopter crash, or if a storm came in and flattened one's tent. We started in the classroom listening to various scenarios and solutions to the myriad things that can go wrong here on this frontier continent. From there, we loaded into the transport vehicle. Transport vehicles are an interesting topic for this region, but I will save that for another dispatch. After some more instruction in the field hut, we then moved out to our camping area. Our first project was to set up the Scott tents. John and I will be sleeping in Scott tents while in the field. These things are rather different from standard camping tents. They weigh about 90 lbs, have four straight poles and are made of a very sturdy rubberized canvas. They have straight walls and no built in floor. Apparently, they are built to withstand ~100 mph winds. We buried all of our BFC sleep kit bags (large duffels containing our sleeping bags and pads) in a heap of snow to make the shell of our quinsy (snow shelter), and cut out snow blocks for a wind wall. Eventually, the instructors left and we were left to our own devices. I took over on digging the tunnel to the quinsy. All said and done, this took about four more hours of snow sawing, and shoveling in very close quarters. Mitch and I were spanked by the time we actually finished the connecting hole, and dug out the bottom of the shelter to fit three people. Originally, we were expecting a shelter that would fit 5 or so people. We ended with very snug space for three. But it totally kept out the wind out, was fairly warm, and the roof glowed a soft, lovely blue.

Sleeping in such a new environment can be a challenge, especially in close quarters with two people you barely know. Fortunately Mitch and May were both great companions, being excited, easy going and good humored about the challenges we had in not knocking off snow onto ourselves, not rolling over into each other or a snow wall and frequently needing to get up, shimmy out of the very skinny access hole and pee. After the day's exhausting work, I was hungry for about 24 hours straight. My tummy growled all night. My muscles all over my body are still sore and tight. I was dry, but needing to pee quite often. I think I slept a total of about 4 hours this night… the same amount I slept both the night prior, and also the night after (writing up this dispatch). My eyes hurt quite a bit as I finish this dispatch. As I type, and I look out the window, the snow is coming down, not hard, but more than a dusting. From what I heard, this is enough snowfall to stop the helicopter flights. The schedule has already been backed up due to the snow yesterday morning. This will probably further delay our helo flight, possibly until tomorrow.

I had lots more I wanted to write about, but we are tentatively scheduled to fly out of here this morning, and I have an hour to pack a lunch and haul all of my bags out to the flight pad. If our flight gets delayed, I'll probably be sending out an addition to this dispatch.

Ciao!

Dave Down Under - Dispatch 1 - Disconcerting Daylight


The latest from Dave...

You can hear it a thousand times, but it is impossible to comprehend how disorienting it is to have the the same sunlight 24 hours a day. You live by being religious to your clock. What time will you go to bed? After dark? Nope. When you will get up? As the sun comes up? Nope. I have now been on Ross Island of the Antarctic Continent for 24 hours... and the daylight has been exactly the same hue and intensity. The only modulations are the cloud cover and direction from which it's beaming. It feels like late evening all day. It's pretty surreal.

I was pretty wrecked by the time I got to bed last night. To quote John (my advisor), I looked "positively shattered." But with full sunlight leaking through the blinds, it was really hard to get to sleep, especially with chatty roommates and being keyed up from a pretty interesting flight. But I managed to get enough sleep to function pretty well today. John worked me pretty hard today. We were packing and schlepping gear all day. We are almost completely packed for our work out in the Dry Valleys, so the hard work is done. I have the day almost completely to myself tomorrow, and most of Monday as well. On Tuesday, I will begin my Happy Camper Training, an extreme weather survival course. We will dig snow trenches and sleep there overnight. This should make for some interesting material to write about.

People here are really quite nice. There's definitely severe clique-ishness to the staff, but they are all here to do a job, and 85% of that job description is to be effective at helping the scientific community. The other 15% is not to go mental. The clique factor is a natural result of working in close quarters with a limited group of people. A few of those people, the staffers, are around for five to twelve months. But most of the people who come through are transients. The scientists. We are referred to as beakers, like the glass beaker, and the term was probably lifted from one of my favorite muppets. As far as name calling goes, I think I like this one quite a bit!

I am about to head out this evening to join the one staffer who has been extremely outgoing and sweet to me. She held a wet rag on the back of my neck as I pinched my nose to stop the leak I sprung on the C-130 flight. She is a semi-retired grandmother. She and her husband have come down for the last five years to work 5 months of the year (the busy part). Sampling the legendary (or infamous) McMurdo nightlife should also be good fodder for writing material.

Dave Down Under - Out of the frying pan, into the freezer


The latest from Dave...

In my life-time, I've managed to do a lot of traveling, and most of this traveling has occurred in decent chunks of time. This is the longest single trip away from home I've had yet. All said and done, I will have been away for at least eight weeks, and probably closer to ten. That has yet to be determined. However, unlike most of the trips I've had, where I've had essentially one region (city, country, etc) that I've focused on, this trip has me in both Australia and Antarctica. The only thing that they have in common is they are both in the Southern Hemisphere.

At the time of this typing, I am in Christchurch, New Zealand. The United States Antarctic Terminal of the Christchurch airport to be specific. Our flight into McMurdo Station has been delayed by a few hours, so we're all hanging out in a range of cloths. The stupid, new people didn't pack comfy cloths to change into. The smart or experienced people brought standard clothing to change into in the event of a delay. So here I sit typing, in wool socks, insulated Carhart bibs, and thankfully, a short sleeve T-shirt. My ultra warm boots are off. I am uncomfortably warm. But I think there are a handful of people who have it even worse. Next time (God permitting) I will do things a little differently!

This trip started on November 21th, when my adviser, John, and I flew from Seattle to Sydney, Australia. Our end goal was sample analyses at Australia National University (ANU) in Canberra. However, we had a planned layover in Sydney so we could spend some time with John's parents. I only got to meet John's mother, as John's father was in the hospital recovering from a hip replacement. John's mother is a lovely woman, and we had a very nice, albeit short visit in the Sydney suburbs. My favorite aspect of the stay was the fantastic birds that had been trained to show up at 9am and 5pm for daily feedings. Magpies, Kookaburra's, Rainbow Lorikeets all congregated at such close proximity that I sometimes had to back off because my lens wouldn't focus that closely.

Early the next morning, we were off onto another plane to Canberra, where we would be working on our low level Cl-36 samples. The reason I was there in particular was my seawater samples that required long runs, and my experience running particle accelerators allowed me to be of assistance while we ran overnight. Keith, the director of the accelerator facility, hosted John and I. Our first couple of days in Canberra were relatively quiet. I packed sample cathodes and read quite a bit. When we were scheduled to start up, on a walk through, I noticed a water puddle underneath a primary bending magnet. This delayed our startup a bit. After the cooling water hoses had been replaced, we started turning everything else on. After the initial tuning of the accelerator, something dropped out. The power supply associated with the very same magnet died. This problem was one that killed our ability to run that day, and most of the next. After more reading and simply keeping myself busy, we finally got up and running, and Keith started teaching John and I how to run the accelerator. This allowed us to run overnight and make up for some of the time we lost to the break down. We ran my seawater chlorine samples all night, and processed some of the data. The quality of the data exceeded our expectations. Keith had done a superb job of letting the sample chamber bake out lingering chlorine from past runs, and by running the samples for some time, we were able to get excellent statistics. These samples probably have the lowest Cl/Cl36 ratios ever successfully measured with this statistical quality. Ever. So this is pretty exciting, and John and I made it through a fairly long night on coffee and the excitement of getting such fantastic data! That morning, Keith showed up at 8am to relieve us. We went home and slept for about 4 ½ hours, and went back in to the lab to see the rest of the results. All in all, it was a pretty exciting couple of days. My MS is pretty well ensured, with the last few months of paper writing, and this data collection. John thinks another paper to a prominent journal is in order, and there is much more work to be done that will fit in nicely with my PhD pursuits. John left for Sydney to spend time with family on Saturday, and I stayed with Keith through Sunday to wrap up logistics and help out in the lab.

Monday morning (Dec 1st), I dropped off my cold weather gear at a freight service to ship it to New Zealand, and then I was off in my rental car to Jervis Bay to go hunt down wildlife and check out the famous coastline. I enjoyed being lazy while there. Belinda, the owner of the backpacker I was staying in, found me lazing on the couch with my laptop quite often. It was nice to have a leisurely schedule of going out and taking pictures, chilling on the couch sorting pictures, going out for dinner and beer (by myself unfortunately), and hanging out with Tim, Maria, Vanessa and the other Swiss girl who's name I don't recall at the moment. I went out on a whale watching cruise, and only saw dolphins, spent copious amounts of time at Booderee National Park where I saw heaps of birds, an echidna and kangaroos. On my way back (Dec 4th), I swung by Pigeon House Mountain, and did a high speed ascent. I surprised myself by doing ~1,500 vertical feet in 46 minutes. And it was a lovely hike. On a clearer day, the views would have been spectacular.

That evening, I flew to Brisbane where Tracy, and ex-girlfriend lives. She and her husband Adrienne picked me up at the airport and we all went out for a late dinner and beer. Upon leaving the plane, I was hit by the wall of heat and humidity. Canberra and the coast were still warming up, but Brisbane was already there. This marks the beginning of about three weeks of continuous sweating! Tracy and Adrienne took me out to Fraser Island for off-roading adventure and stunning beaches (I got to drive on fluffy sand beaches which are notorious for bogging inexperienced drivers). We also went out to the Mt. Coot-tha Botanical Gardens, the Glass House Mountains, and a handful of other city activities, including checking out the in-city riverfront rock climbing wall. Yup, ~50 feet high, the wall extends ~200 meters along the riverfront, and affords what looks like ~50 routes, maybe more.

Valerie flew in on Thursday the 10th, and had a meeting at University of Queensland with a colleague who is doing similar research on Friday. Saturday afternoon Tracy, Val and I all drove down to Evans Head, and small town south of Byron Bay. We got down there that evening so we could be up bright and early for our kayak tour of the Evans River estuarial region. Sergio, a friend of Tracy and Adrienne's runs kayak tours there, and we got a very personalized tour, and learned a tremendous amount about the local eco system. On our way back home, we stopped in the famous Byron Bay, a hippie enclave turned beach resort hotspot.

That night, we repacked and prepared for our 6am flight to Cairns. Stacy and Daniel picked us up at the airport and we drove up to Port Douglas where they have an apartment. I think I've rambled a little too much at this point, so I'm going to save the juicy details of our time in the Daintree for my post to the website, so here's the quick version:

I got to see two adult and three baby cassowaries, a goanna (monitor lizard), Boyds Forest Dragons, fruit bats, praying mantises, stick insects (one of which walked over my face), crazy spiders, and amazingly camouflaged katydids. Almost all of which I was able to photograph to some extent. We all went out to snorkel on the Great Barrier Reef, where we saw sting rays, a cuttlefish, giant clams (one was almost three feet long), stunning coral, and a usual assortment of amazingly colorful fish. Daniel and I also did a creek walk up to a beautiful set of waterfalls.

Ok, I'm all typed out. Sorry for making this so long. I'll be posting more details and pictures on the web site some day… not sure when.

I hope everyone is well!!!

Ciao!

Dave Down Under - Introduction


Greetings! David Argento here. Sean has asked me to send some dispatches from my upcoming field research trip to Antarctica so I thought I'd provide a little introduction...some information about me and this trip.

I am a graduate student at the University of Washington. I originally came from a background in Physics, and have a decent amount of experience in radiation field. I came back to the school when I found a research professor, Dr. John Stone, who was using radiation effects on rocks to date the length of time they had been at the surface of the earth. The field is referred to as Cosmogenic Nuclides, and beyond simply dating a rock, we can infer erosion rates, and uplift rates on the rocks. By dating the rocks, we can often date the greatest extent of a glacier by dating the rocks left in moraines, and ice sheet maximums. The source of this radiation is outside of the solar system. It is being actively researched by high-energy physicists and astronomers. So while the absolute source of this high-energy radiation is still uncertain, one thing is quite well established: it is remarkably reliable, and seems to have been quite stable in its magnitude for the last billion + years. We are only dating rocks out to ~2 million years maximum under ideal conditions, so this works out quite nicely.

An important aspect of this line of research for me is the outdoor component. I like reading; I like working on computers. But I also need an outdoors outlet, and it seemed like this avenue would bring just that. Unfortunately, for a variety of reasons, the bulk of my work over the last three years has been on computers. This all changed in dramatic fashion this last year. I have spent three weeks in Montana, two weeks in Sicily, a week in Rome, a week in Australia and now four weeks in Antarctica. This is all the research time, and does not count the fun traveling I was able to do because of it.

My advisor and I are about to head out to the McMurdo Dry Valleys, a region that is considered hyper-arid. It seems counter intuitive, since damn near the whole continent is covered in snow, but the vast majority of precipitation is dropped outside of these regions. So these valleys are essentially perma-frosted deserts. Because of the ultra-low precipitation, there is also ultra-low erosion. This results in rocks that are saturated in the radio-isotopes that are formed from cosmic radiation, because they’ve been “baking” as long as possible. So we're going to a spot to collect deep rock cores for calibration purposes.

The primary question we are looking to answer is just how significant the different radiation types are compared to each other. The bulk of the radiation we care about is neutrons. We tend to think about these the most, because they cause the greatest amount of isotope production at the surface of the earth. Muons (massive, energetic versions of electrons) are quite prevalent in number, but they’re kinda slippery. The don’t interact with matter as strongly as neutrons do. So while they don’t produce as much of the isotopic signal at the surface, they survive longer in their dive into the earth. Hence, they form a considerable signal of these isotopes much deeper in the earth when compared to neutrons. We will be taking deep (20-30 meters) rock cores at two separate sites, to be able to sample two types of rock at similar locations, and hopefully gleaning good empirical insight to these phenomena.
