Journal Entry

What have I been doing? So far I have been pretty busy. The CosRay building is being decommissioned. It is fairly far away from the station and is difficut to maintain so they are shutting it down. The placement of the CosRay building wasn't an accident though. McMurdo Station used to have a nuclear reactor. The CosRay building was moved to the opposite side of Observation Hill so there was a mountain in between the neutron monitors and the reactor. They didn't want to detect the neutrons from the reactor and the mountain provided shielding. The reactor has since been removed to eliminate any chance of affecting the environment. However the neutron monitors are still producing good data and remain the longest continuously running experiment in Antartica. So they want to keep them running. They are being shipped to the South Korean station, Jang Bogo. Jang Bogo is a comparable distance from the magnetic pole so it's a good fit. Even though Jang Bogo is only about 350 km away the neutron monitors will be shipped to New Zealand and then over to Jang Bogo as that there are no regular shipments between the two stations.

Neutron Monitors While InstalledNeutron Monitors While Installed (They just look like a big box, right?!)

The process of pulling apart the neutron monitors is no small task. Remember the neutron monitors are completely enclosed in polyethylene to screen out low energy neutrons and polyethylene is heavy (as my back can attest to.) Oh yeah, each set of detector tubes has about 10 tons of lead. And there are two sets.

Neutron Monitor Cross SectionThis is what is in the box. Each peace of lead is 200 pounds.

Yup, we moved twenty tons of lead on a handcart two hundred pounds at a time. I think I need a nap.

All Packed UpOne set of monitors filled up this shipping container. They had to go get a bigger forklift to move it.

Hey Mr. Thuma, when did you find out the station was being shut down (was it out of he blue?) ?Have you encountered any wildlife?

Armando Caussade

What's your daily routine like?
I am amazed at all the hard work that you, Jim and the team and putting in.

Take care Eric, and thanks for sharing your experience and explaining everything so clearly.

Best!

Dante Prince

Is the experiment using the neutron monitors the only experiment you're carrying out while you're away?

Eric Thuma

Because it was a little over a mile away from the main part of McMurdo Station

Eric Thuma

Well, its not all packed up yet. But after it its i will be still be working with scientists on related projects

Eric Thuma

For the most part but some of the same scientists work on a project at the south pole called IceCube. That is a neutrino detector. So I am learning a lot about that.

Eric Thuma

Thanks Jan. I'll do my best to keep them up. I didn't believe Tim when he said they would take two hours to do but, guess what?! They take two hours to do!

Eric Thuma

There really hasn't been a typical day yet. But I'll try to break it down in a journal. Generally, we get up go to work at CosRay for a bit, walk back for lunch, more work at CosRay, back for a late dinner. Then in the evenings there have been a number of interesting science talks that we have attended. I haven't had much chance for socializing or sightseeing yet but I'll be doing as much as I can after the detectors are squared away.

Lauren Erickson

What different types of animals have you seen so far?

Gaird Brock

Hi, Thuma!Do you guys have any snowmobiles, or those giant sno cat things that they drive in the beginning of National Treasure? If not, then how do you get to places that are further away?
Also how much free time do you get each day?

Eric Thuma

I have seen a lot of seals. And there is this bird down here called a Skua. Its like a huge brown seagull. They want your food.

Eric Thuma

Mostly I have been getting around on foot or bu truck. But there are snowmobiles, trucks with tracks, and larger tracked vehicles.

Armando Caussade

Awesome!
Thanks for taking the time to respond to this query.

And do not forget to go out one "night" at 12:00 am and experience the midnight sun!

Eric Thuma

I will but not tonight We are at condition 2 so I'm staying inside. Maybe I'll get a cup of coffee at the Coffee House.

How many people are down there and how long do they stay typically? Does everyone have many jobs (ie, scientist/researcher and driver/cook/etc)? Or are some people there just to do the latter jobs? (Love the journals!)

Eric Thuma

There are about a 1000 people at McMurdo in the summer. It goes down to a couple hundred for winter overs. South pole station has a much smaller compliment it goes from a couple hundred in the summer to about 40 winter overs. Many people have multiple jobs but there are people who exclusively work one position. Some things get done by everyone for example everyone pitches in to keep living spaces clean. The length of the stay is variable. One of the fuel guys told me that he was down for 6 months but I've seen scientists in and out in two weeks. I guess it depends on what they are doing. Say hi to Aidan for me!

Lily Nowland

Why was the CosRay building so hard to maintain?

Evan Ziehl

If you shipped away the project you are working on, what are you going to do for the rest of your time?

Janet Warburton

Wow. Looks like you are working hard! 10 tons of lead in those boxes? That's amazing. Thanks for posting the great journals!
