April weather was somewhat significant being the coldest April on record averaging -80.7F which was lower by 0.2F than the previous record set in 1998 (records began in 1957). On top of that, we set the second earliest mark in reaching -100F ever recorded dipping to -100.7F on April 13th. It’s only typical that as soon as April ended, we are on a streak of warm and unsettled weather. For instance, temperatures today are supposed to rise into the -30s Fahrenheit. It’s amazing to me that you can have a range of about -65 degrees without any daily help from the sun. If things keep up, which they look like they will for the near future, we are on pace for the warmest May ever! I wonder what is in store for the rest of the winter?

The station atmosphere was much quieter however. We only really had only one major event which was a glycol leak in the power plant. The power plant uses a 60/40 glycol to water ratio to cool the diesel generators. The waste heat from the generators transferred to the glycol mix is then run throughout the station to heat the building. My knowledge of how the whole system works is very limited but as I understand it, a thermostat broke open and created a geyser of glycol. It then landed on some of the exhaust manifolds causing it to vaporize and create a huge cloud in the power plant. This triggered the fire alarm. Luckily it wasn’t one of the loops that carry the bulk of the glycol or it could have been a much worse mess. Over the summer, we had so many false alarms that you kind of become desensitized to it always thinking it’s a false alarm. But when you hear the automated alarm system say that smoke was detected in the power plant, and that it’s not a drill, it really gets the adrenaline pumping. As you can imagine, the power plant is one of the locations on station where you could have things really go wrong.

Everyone on station is assigned to an emergency response team and mine is the fire team. Because we are on are own down here, it is our responsibility to deal with these situations. The fire team had some firefighting training back in Denver before we came down Antarctica and we also try to do some training on our own once a week to keep methods fresh. But we are by no means professionals. Needless to say, I was very relieved to find that the power plant was not engulfed in flames and nobody was injured in the incident. The heart rate definitely jumped initially with the thought that I might actually have to go in and drag someone out of a flaming building. We don’t have fire hoses so all we have are fire extinguishers to use on station (there are fixed water and CO2 suppression systems at various locations however). With all the luxuries that the station has, it’s easy to slip into a false sense of security. These types of incidents are reminders that we are still in a dangerous environment.

There are not any traces of the sun on the horizon any more. When the moon is out, it is like a floodlight on the South Pole. It’s amazing how bright it is. It sure makes walking to the observatory every day much easier. Now the moon has gone below the horizon and it’s extremely dark but the stars are incredible. Yesterday walking back from the Atmospheric Research Observatory (ARO), I was lucky enough to see an iridium flare coupled with a really nice aurora. An iridium flare is when the solar panels of a satellite are at just the right angle that it reflects the sun’s light at you. It does it for just a few seconds as it passes overhead. Unfortunately I did not have my camera ready for a photo.

Well that about does it for the update. Seven months down, six to go!

MCMURDO STATION, ANTARCTICA– Today I had the opportunity to interview Lieutenant Mosher of the McMurdo Station Fire Department. He gave me a tour of the whole firehouse and showed me all the fire trucks they use. We had a lot to talk about because I was really interested in what separated this Fire Department from all others that we’re familiar with back home. I even got to wear all the gear the firefighters use daily. The real reason was that I really wanted to go for a ride in one of the fire trucks out on a call with them…

Antarctic Fire Department, McMurdo Station Firehouse.

An important distinction that Lieutenant Mosher made was that the firehouse at McMurdo Station is the only one around. This means that here at McMurdo, the men and women who protect everyone who live and work down here have no back up if something serious happens. The fire department is the last line of defense to keep this station running. The firefighters don’t just fight the rare fire that happens, they also know how to make sure the power and heating plants are operational. If those went down in an accident, it would be entirely catastrophic for the entire community.

Lieutenant Mosher and I also talked about how the extreme environment effects how the firefighters do things differently down here in Antarctica. Usually, we’re used to firefighters spraying water on fires. Down here, if they did that, the water would freeze so fast, that a really large mess would be made. To combat this, the firefighters put glycol into the water so that it doesn’t freeze. Because the regulations for environmental protection are so stringent here, any water with glycol that is sprayed onto the ground surface, whether snow or rocks and dirt, must be cleaned up afterward. So of course the first priority of the fire department is to keep everyone safe and to address any situation as it comes up. But then, after a fire situation has been completed, they must become a Hazardous Waste Team and remove the contamination by putting the chemical-soaked snow or ground into containers that will be shipped off of Antarctica for proper disposal in the United States.

Many of the vehicles that are used on station closely resemble the fire trucks and ambulances that I’m used to seeing at home. The major difference with these is that they have really big tires and are elevated off of the ground to be able to get through the snowiest of conditions. It’s the other vehicles that were really interesting to me. Some of the trucks the McMurdo Fire Department uses have tracks instead of wheels. These are really useful in really bad weather conditions or when the firefighters have to go up or down really big hills or rugged terrain. The vehicles that the Fire Department uses out at Pegasus Field where the airplanes land are unlike anything I’ve ever seen. These trucks are huge, massive even. They have tracks like a military tank has and are highly articulated so they can maneuver in just about any direction.

Finally Lieutenant Mosher let me get suited up in all the gear that the firefighters wear. He took me up to the loft of the firehouse where there is a huge storage of clothing in all different sizes. First he had me try on a helmet to make sure that it fit. And little by little, I started looking like a real fireman. It’s very important that this specialized clothing fit just right.

Trying on a helmet.

The clothes that the firemen wear are really heavy because they are composed of multiple layers. And it’s hard to move around in them. One layer is for warmth. Another is fire-resistant. The outside layer defends against tears and rips. It must be really hard to be a fireman and have to carry heavy hoses and all their equipment while wearing these clothes. I think many firefighters, not just here at McMurdo Station, are in very good physical shape partially because of this.

No firefighter would be complete if they didn’t wear an air tank on their back. The mask on their face not only keeps them protected from the heat of a fire, but it also supplies fresh air to them if they have to run into a burning building. The smoke and fumes from a fire make it very difficult for a firefighter to advance into it if someone is trapped inside and needs to be rescued.

When Lieutenant Mosher got me all suited up, from the loft I could see the big garage door open. A truck was coming back to the firehouse! Maybe this would be my chance to hop a ride for the next call. After all, I had all my fireman gear on already.

As I climbed down the ladder of the loft, I started getting really excited that I would be able to go out with the fire department on the next call.

But then Lieutenant Mosher explained to me that it’s not just about riding around in a big truck. Every fire fighter at the McMurdo Station Fire Department has to help out with all the chores necessary to keep the firehouse functioning. So, wouldn’t you know it, Lieutenant Mosher asked me to sweep the floor of the garage where they keep all the trucks. Of course I agreed because I wanted to experience what it was like to be a firefighter in Antarctica.

Once I was done with sweeping, I again was really thrilled because I thought “Now’s my chance!” But Lieutenant Mosher told me that all the trucks have to get cleaned everyday. And then he said that once a week, the trucks get an extra special cleaning, and that today was the day! So he handed me a bucket of soapy water and a sponge and off I went to scrub the trucks down. The other firefighters who were around the station house at the time thought it was really funny that the “newbie” was doing their job of making sure everything was clean and tidy.

My chance finally came. After I finished my chores, I was able to get on a truck and go out on a call.

Full gear on and ready to go out on a call with Lieutenant Mosher.

I want to thank Lieutenant Mosher for taking of his time to spend with me to answer my questions about how the McMurdo Station Fire Department is different than other stations back home. It was a nice treat to be able to experience what it’s like to be a firefighter in Antarctica, and I have the utmost respect for the men and women who put their own lives at risk to keep all of us safe on station.

Stay tuned….a video of my day at the McMurdo Station Fire Department will be coming soon!
