Discovery Hut and Ob Hill Loop
Here are some pictures and descriptions of two short excursions I went on last week. Last Wednesday night I took a tour of the Discovery Hut, which is maybe a mile from McMurdo on Hut Point. This structure was built in 1901 by Scott’s Discovery expedition, and used later by Scott’s Terra Nova expedition, and two of Shackleton’s expeditions. The Americans dug it out in the late 1950’s when they built McMurdo. It was originally built in Australia. Over the years it has been pillaged, and now is locked and only opened for tours like the one I went on. Even with the age and vandalism, it is extremely well preserved. The first sight (and smell) when one walks inside is a rotting seal, left over from one of the expeditions. With the perennially cold temperatures, it is somewhat preserved, although it was a bit “thawed”, to put it nicely, when I was in there, as it had been above freezing for several days in January. This building was mainly used for storage and rendezvous, especially with the later expeditions, so it is mainly filled with supplies. Here are some pictures from inside:
On the next post I will have some pictures of my field trips to automatic weather stations at Pegasus and Williams airfields.

Life on the ice: Part II
Work
I am here under auspices of the Antarctic Mesoscale Prediction System (AMPS) project. AMPS is a real-time computer model used by the U.S. Antarctic Program in support of their flight, ship, and field operations. It uses the Weather Research and Forecasting (WRF) model for its computations, which is a popular choice for regional applications in the meteorology community. The version used in AMPS has been optimized for polar conditions by some of the other folks in my advisors research group, both past and present.
My purpose here is to work with the forecasters to find out how well AMPS has performed this field season. This is the first season that WRF is used within the AMPS framework, so we are especially interested in what the forecasters have seen. I follow the model forecasts (they come out twice a day) along with the satellite imagery and other observations to gauge how the model is doing for various weather situations. Then I discuss those situations with the forecasters, and often that jogs their memories about a similar situation with the model earlier in the season. I also take any suggestions as far as any additional products they would like to see produced for the operational forecasts, but those will be redirected to the folks that handle the actual production of the model runs (NCAR in Boulder). I am also keeping up with my normal work from back home while I am here, as the work specific to here does not take up all of my time.
I get a lot out of just discussing the weather with the forecasters. Most of them are seasoned forecasters in the Antarctic and have a lot of knowledge of and experience with the weather patterns and other features local to this area. They are much better at interpreting how certain weather pattern will develop, and how to interpret satellite imagery, than I am. In my work I easily get out of the mindset of following the day-to-day weather, so it’s a good jolt of practical application for me. There are four forecasters here right now, and three of them work four 12 hour shifts on, then two days off. One of them works 8-9 hours every day as the briefing forecasters – preparing most of the briefs for the morning flights. Several other forecasters work remotely in Charleston, SC. In addition, there are several weather observers who work at the airfields and at the weather office, handling observations and launching weather balloons. One forecaster and one observer will stay for the winter. Most if not all of the forecasters and observers are ex-military or currently in the reserves, and have served all over the world (Iraq, Afghanistan, Germany, Bahrain, Korea, among other places).
Activities
There are a wide range of activities to keep oneself occupied outside of work. I have been trying to do some running while I am here, although sinus problems have cut into that a bit. There is a building with several treadmills and other cardio machines in it. There is a building with weights and also a bowling alley, but that building has been closed most of the season due to structural issues. There are two bars, one smoking and one non-smoking. Several of the higher-ups in the operations side were in from Charleston last week, and there was a party with brats and burgers at the smoking bar. Being in there was a bit of a shock, as I’m used to the public smoking ban back home. The recreation department always has activities going on, such as the tour of the Discovery Hut that I went on last week (more on that in the next post). There are several trails around the outskirts of the base that are open weather permitting. Last visit I did the Ob Hill hike…last Friday evening I walked the trail around Ob Hill.
New Zealand’s Scott Base is only a few miles down the road, and yesterday I went to visit their station store. The also have an “American Night” at their bar on Thursday nights. There is a church here (Chapel of the Snows), and I went to their Protestant service this morning. On the weather end of things, I’m hoping I can help launch a weather balloon again sometime this week. I had to attend two meetings, both the first Saturday I was here. The first was for recreational travel, which was just a brief video. The second was a refresher course of “happy camper school”, which I first took back in 2006. It was about three hours, and all indoors. I barely remembered anything. I learned that I can’t tie knots, and overall, I would probably be borderline useless in a survival situation.

Life on the ice: Part I
So I’ve been here for over a week now, and have adjusted to life here at McMurdo. Outside of some computing issues (more on that in the next post) and sinus problems, my stay has been uneventful. The weather has been beautiful – there were a few cloudy days earlier this week, but otherwise sunny and low 30’s during the day, and sunny and low 20’s at night. The sun is above the horizon 24 hours a day, but there is a small diurnal cycle, and the sun angle lowers a bit at night. I think that “dusk” conditions begin to appear in late February before the dark winter begins to set in around late April. This docile weather is nice for outdoor activities and just everyday life here, but boring for me. There’s a hint of something in the forecast models on Sunday and Monday, but it’s a little early to have a good idea on that. There was some atmospheric wave activity over the terrain features south of here the other night:
The horizontal line of clear skies is the descending air on the lee side of Minna Bluff. It’s exciting for me to see something like this in person, that I’ve seen on satellite imagery from home many times.
Enough about weather (for the most part)…below are some details about my time here so far.
Accommodations
There are several dorm buildings here, with several categories of comfort. I am in 203c this year, which is slightly different than 208, which I was in back in 2006. In 208 I had one roommate until he moved out about 10 days into my stay, and we shared a bathroom with another room. There was a TV and mini fridge. Here, I also have one roommate, but there is a communal bathroom for the floor, a mini fridge, but no TV. It’s slightly smaller as well. It seems to be the place where they are putting many of the short-timers and non-PI science people. It’s not too bad. I really haven’t watched much TV, I’ve been reading instead, which is probably good. I just met my roommate two days ago, as he was in the field for all but three nights. He is manager of the ice core drilling group at the University of Wisconsin-Madison. He went north today, so there’s a good chance I will have the room to myself for the rest of my stay. The base is clearing out, as the field season is wrapping up and the place closes for the winter in under a month. At peak this season there were about 950 people, down from the nearly 1200 there have been for some seasons. Only about 150 people remain for the winter. Here are two pictures of the room:
Food
Food is one of the major topics of conversation here. There are four meals here – breakfast, lunch, dinner, and “mid-rats”. Mid-rats is midnight rations. It is only available from 12:00-12:30 AM for those that work night shifts. The next half hour is open game. My hours here are approximately 1 PM to 1 AM, so I can stay out of the way of morning flight briefings in the weather office. So lunch is my breakfast, dinner is my lunch, and mid-rats my dinner. Sometimes they check ID cards at mid-rats, but I just go with the weather office employees and it’s no problem.
The conversation tends to drift towards the negative end of things. That is, if there’s a good meal, it’s not really mentioned, but people don’t hesitate to bitch about a bad one. Then the conversation turns to how people would prepare something similar themselves, or some variation of it they really like. Now, I can see this from those that have been here all season. After several rotations of the same meals, it might get old pretty quick. I think it’s the lack of choice that gets to people. Personally, I absolutely love it here. First of all, it is FREE. This is saving me several hundreds of dollars for the time I am here. You can have as much as you want – just take what you eat, and eat what you take. And I don’t have to make it or do dishes afterwards. Just show up, like pigs at a trough. Second, the desserts are fantastic. This is a widely accepted opinion, even from the seasoned personnel here. Cheesecake, pies, cookies, on down the line. Delicious. Plus, there is a soft-serve ice cream machine (“Frosty Boy”), which I have probably frequented too much for my own health. Toppings are also available.
The mains tend to center around whole foods (a lot of chicken, to the disgrace of some), and at least to short-timers like me, there’s enough rotation. There is always some kind of bread, a wide variety of fruit, and fresh vegetables as long as the planes are flying between here and Christchurch. There is also a sandwich line. There is no soda in the dining hall (only for purchase from the station store), but a wide variety of juice. The only knock might be the lack of actual milk (it’s powdered).
I can’t get over some of the quality of food they get down here. Earlier this week we had cherries. Those are what, like $6 per pound back home, and only seasonal in early summer? And one night they had tenderloin cutlets, cooked perfectly (light red to pink on the inside). I never buy that back home because it is so expensive. Sunday brunch is usually amazing, with a wide selection of pastries. I am already looking forward to surf and turf (shrimp and prime rib) on Sunday…I remember that meal fondly from last time.
Check in next time for details of my work and other activities going on here…
