Today the sun was back out, the wind was calm and the snow and ice of McMurdo Sound had regained the brilliance that we have become accustomed to here. It’s my last day in Antarctica – tomorrow I will board the LC-130 and head back home. Until that time though, I’m going to enjoy the time I have left and see how the test site has changed since Monday.

Commuting to Work

I boarded the Delta at 7:15 with the drillers, a couple of electricians, John, Tim, Mike, and Betty of the WISSARD team, and Kathy, our excellent and good natured driver. A Delta is big, heavy, and not terribly fast, but it does get there. On the rough areas in the road it bucks and bounces, but its huge tires absorb a lot of the shock and smooth out the ride as much as possible.

Delta at Transition
This Delta is hauling people out onto the ice road after leaving McMurdo. It has stopped at the transition to knock dirt off the underside of the vehicle to keep the dirt from breaking down the ice on the road.

The trip out to our test site takes about 45 minutes. The route goes from Derelict Junction out to Highway 1, over the pass and down to Scott Base, then after a brief stop at the transition to knock dirt off of the underside, we ease slowly over the cracks in the ice that mark the end of land and beginning of the ice shelf. This is the roughest part of the ride – the transition requires constant maintenance by the road crews because here the road is always moving and breaking. They bring new snow and ice in to fill in holes and try to level it out, but it’s just plain rough. Once across, the road smoothes out and the gentle rocking and swaying of the Delta tends to make everyone a little drowsy. Some of us fall asleep.

Riding in Delta
Here's our morning crew riding to work in the Delta. Tim is really passed out!

Changes

When we arrive at the WISSARD site, I take a quick look around to see what’s changed. There are not big changes, but many little ones that you need to look for. The LARS (Launch and Recovery Sled - the work deck above the snow) has new equipment mounted on it, safety railing is being installed, and the UV (ultraviolet light) purifier is down in the drilling well. Around the deck more of the labs and control containers have been put into place and ramps installed to connect them to the LARS for easy access.

Rudy and Winch
Rudy, an engineer from DOER, working on the hydraulic motor and winch that will be used to lower the test instruments into the drill hole.

In the RCU (Reel Control Unit), the big hose that carries the hot water has been rolled onto its roller and fed into the crescent overhead, looking ready to go and start drilling! The big generators aren’t running yet, but they are closer and most of the wiring has been completed. Later in the day we will hear the deep-throated rumble as they are brought to life and tested. Electric power is critical to keep everything running.

Crescent
This is called the crescent. It guides the hose down to where the drill hole will be underneath it. The hose carries the hot water that actually melts the ice away and makes the hole down thr. The water is 80C (that's around 190 degrees Fahrenheit)

Big Gen
This is one of two big generators that supply electric power to the drilling system. There's not a lot to see here, but that big diesel engine has to work to turn the generator and produce electricity.

Inside the WISSARD container Tim and John are reconstructing wires by soldering sections together. They had worked on this much of yesterday and still had a ways to go before the wiring harnesses were complete.

Soldering bench
The soldering bench where John and Tim were rebuilding cables.

Mike and Rudy were working on the equipment and instrumentation, making changes and repairs. I worked on putting up a fan to get fresh air into the soldering areas and bolted a brace onto the “smart” winch. Dave, our videographer, showed up about 10:45 and I showed him around the site. He was looking for material to use in the documentation of our work. He wants to show an audience some of the parts of science that isn’t often seen – things like just making sure the bolts are tight.

Dave Monk
Dave Monk and the tractor he just got done video taping.

Dave

I need to tell you a little about Dave Monk. He lives in Chicago and is a professional videographer. He was asked to be a part of WISSARD to document what goes into a big science project and to include some of the other aspects of life away from home, family, and the towns that many of us are familiar with. He has the eye of an artist and the skills of a story teller. He’s also a lot of fun to be around. He sees what we are all doing and how we are living from a totally different viewpoint. He makes us aware of it too. Because of Dave, we open our eyes up and see much, much more of what we do every day.

Moving lab
The tractor is dragging the sled-mounted lab sideways to get it into position. The drivers of those big tractors have amazing skill and ability in placing those long sleds exactly where they need to be. It's way better than watching Dancing With the Stars because here the dancer is a tractor.

He’s also unpredictable. One day as we were making a group photo he was crouched down in the front row, and right as the picture was being taken he leaped out and across the snow, like a cat pouncing on its prey. I caught part of the move in the picture. If he’d been the one taking the picture he would have expected a silly move like that and caught the whole thing.

Dave Jumping
Dave Monk - clown and expert videographer. Can you tell which one he is?

Dave, being a videographer, also likes catching people doing things or in motion. I guess that makes sense since he is taking moving pictures. We often got orders to walk toward the camera, don’t look at the camera, don’t skip, or do anything else silly. He got many minutes of John and Tim soldering; he and I got video of blasting to break up the ice at the ice pier; he would watch seals for long periods of time, just waiting for them to move (they don’t move much up on the ice – just sleep). If it’s possible to be hyperactive and infinitely patient at the same time, that’s Dave.

Subtle Changes on the Road to Success

Overall the test site was moving ahead and pretty much keeping on schedule. The changes were subtle, but important to the overall success of the project. All the little things have to be working. That means the drill need to work and so do the data collection tools that the scientists rely on. To understand the data, you also need to do chemical analysis. The labs have to have electricity and water in them. You also need places for everyone to eat, sleep, and even play when they have time off. You’ve seen some of my earlier journal entries that talk about all of these things. Every change I’ve seen is important if the project is going to be successful!

Chem Lab
The inside of the chemistry lab. It's inside a long trailer like a semi-truck trailer, but it has better equipment and more capability than the chemistry lab in my school. They can do wet chemical analysis, radioactive isotope analysis, sprectroscopy, you name it.

Mike LeBaron and Tractor
This is me wishing I could go play on the big tractor. It's bigger than anything I drove on a farm when growing up. Note that I've carefully color-coordinated my outfit to match the tractor.
