Journal Entry

We've been here at Lake Joyce for a week now! Time sure flies. I'd love to share some photos and a bit about our living conditions here in camp.

Endurance tentOur Endurance tent – for cooking and hanging out.

Our first priority was to get our "endurance"-style tent set up. This is our communal tent where we cook, eat, and hang out. Its about 21 feet by 8 feet, and has many, many guy lines anchoring it down. The wind here gets really fierce, and the other night there was a particularly powerful windstorm. We were in the endurance tent when it happened and we could hear gravel pelting the outside of the tent. Inside the tent is crowded with stuff. At one end is a Coleman two burner stove on a table with a small heater underneath, and a second table for prepping our food. The other end has a camp chair for each of us and boxes of food stashed where ever they will fit. We also have a station of buckets for different kinds of wastes, which must be separated before they can be sent back to McMurdo. Outside the tent, we have a white box for storage (“the freezer”), some propane tanks for the stove and heater, and also a portable solar installation for recharging radios and computers. We call this tent "upstairs" as compared to the tent down on the ice where we have a lab set up ("downstairs").

Also in our camp is a tent for each of us. These are very sturdy North Face four season tents. They've also been anchored down very well. Even so, Megan's tent was nearly airborne the other night during the windstorm. While in mine that night, I could feel the wind getting under the tent and rocking me in my sleeping bag. Our tents aren't heated but I've been staying warm. I have a ridiculous amount of stuff on me at night that includes a fleece liner sleeping bag and two regular sleeping bags rated to -40°F, and Big Red coat on top of that. You'd never find me in there!

Personal tentsSome of our personal tents.

The last tent to be set up is our Scott tent. A Scott tent is a style of tent shaped like a pyramid and named after Antarctic explorer Robert Scott. Our Scott tent is the toilet tent. Our toilet is a box, with toilet seat on it and a bucket inside (classy, right?). Before getting the Scott tent up, the box was just sitting behind a big rock and while it did have a spectacular view, everyone agrees that the tent was a welcome addition. The big drums on the side of the Scott tent are for liquid wastes that must be flown by helicopter back to McMurdo Station.

We've had a long and successful day of drilling in the ice. It's nearly dinner time and my turn to cook, so I'm going to go make some dijon chicken with rice now. Yummy!

Maxwell P, Spr…

How much wind would it take to knock over the "endurance"-style tent?

Kevin E Spring…

I know that Antarctica is usually always cold but because you're closer to a lake is it colder?

Edison V

Hi. I was wondering, do the big drums that store the waist ever stink up the place? Thanks in advance.

Erick o spring…

Have you encountred a live laeopard seal lion

The photos of your camp are wonderful in revealing the absence of snow ... I understood the concept of the Dry Valley before but the photos really do demonstrate how unexpectedly free of snow and ice it is.

Mitchell H

How do you cook inside the tent?

Dawn

I can answer some of these questions since I'm the one who sent the team Lucy is on to Lake Joyce.
If an endurance tent is well anchored to the ground with ropes and rocks, it won't get knocked over until the wind is strong enough to bend aluminum poles that are about an inch in diameter with walls about 1/8 of an inch thick. They are really strong. However, if the wind gets under the tent and lifts it up, the ropes won't hold very well and if they come loose, the tent will collapse. Thus, having lots of heavy things - like canned food - around the inside edge of the tent, plus rocks on the outside "skirt" are really important.

Dawn

Lakes cool their surroundings when the water at their surface evaporates by absorbing heat from the atmosphere. The same thing happens when ice on a lake surface "sublimates", in other words it goes from ice to water vapor. However, the rate of sublimation is much lower than the rate of evaporation for most lakes. And the ground is really really cold. Thus, I don't remember ever noticing that it was colder as I got closer to an ice-covered lake. (I'm the professor who sent Lucy and the rest of the team to Lake Joyce and I've been to similar lakes several times before, although I'm not there now.)

Dawn

The drums don't stink for two reasons. First, the waste in them tends to freeze this time of year because it is so cold. This is actually something that is VERY important to pay attention to because pee, like water, expands when it freezes. You never want to fill up a barrel so full that it overflows when it freezes. Because water expands about 10% when it freezes, always switch to a new barrel when it's about 80% full.
Second, the hole at the top of the barrel is small and you can always put the cap on. That keeps any smell that might form when the weather is warmer from bothering camp.

The team cooks on a propane stove. In most cases, it is dangerous to cook with a gas stove inside a tent because CO2 and CO can accumulate. At high enough levels, these gases can and have killed people. Thus, the Antarctic field training always teaches the team how to keep good ventilation in the tent. Even when it is very cold out, they will have the vents open whenever they are using the stove. This is EXTREMELY important to remember, no matter where you are camping out.

How cold is it in the tent

Julissa Fajard…

What happens when the wind is too strong? Does the tent collapse and what happens to the people living inside? Where do they go?

Annelise M, Sp…

I was wondering how many tents you sent up in total, and how long it took to set them all up? I'm thinking it probably took you a few days.

Anna R., Sprin…

What is your favorite part about being at Lake Joyce? What is your least favorite part? Thanks so much if you do decide to answer this! I hope you're having a great time so far, and I can't wait to hear more about it through more journal entries!

Jasper E. Spri…

Hello Ms.Coleman. I have a question about your Lake Joyce camp. Does the sun ever set there, does it always stay light? Thank You.

Suzanne Cable …

Lucy, Kim and Suzanne are hard at work conducting citizen science on the hot and humid island of Bonaire (off the coast of Venezuela in the Caribbean Sea). While you are searching for stromatolites in water under ice, we are searching for super sized and one of the world's largest algae growing on pneumatophores on red mangrove trees. The turtles and pretty reef fish are stunning too. Tomorrow we continue our quest for seahorses. We love your reports of life near the ice and anxiously await your next report. Send more pictures soon. How large is your algae there? What's the most colorful stromatolites you've seen so far? Do they look like the stromatolites from Glacier NP? Have you seen any seahorses yet? Lots of love. Wish we were there with you, Kim and Suzanne

Samantha,S , S…

How wide are the drillings in the ice and What kind of tool do use to drill in the ice? Why do you need to drill in the ice?

Nuelle J, Spri…

How did you find out that the microbial communities are the same as they were a billion years ago?

Martin soto

Is it fun and exciting studying in Antarctica or is it frustrating some times.

Lucy Coleman

Hi Julissa,
Our tent is very firmly anchored, and unlikely to collapse. If it did, we'd still be able to crawl out and regroup in one of our smaller tents.

Lucy Coleman

Hi Mitchell,

We have a propane Coleman two burner stove that's quite easy to use. We need to be careful to not let carbon monoxide accumulate as a result of using the stove, but we have a detector in the tent that will tell us if levels get unsafe. Clean up is a bit of a challenge too. We want to wash our dishes but we can't generate a lot of wastewater that would have to be flown out with us. Its a balancing act!

Lucy Coleman

Hi Jasper,
The sun doesn't set, it just makes a big circle around the sky everyday. However, at one point in the evening it does go behind a mountain, and we are in shadows that feel much colder than when the sun is shining.

Lucy Coleman

Hi Anna,
I am having a great time! I love learning more about how scientists do science, being in a wilderness setting, and getting to know some really smart and fun people. My least favorite part is not having a flushing toilet.

Lucy Coleman

Hi Annelise,
Well, our endurance tent and 5 personal tents took about 5 hours to set up, but we were doing other things at the same time, like moving materials to better locations. The Scott tent took an hour to set up, but that was a couple of days after we got here. A lot of our set up had to do with making sure everything was lashed down outside or organized inside the endurance tent. The temperature in the tent varies from about 40°F to 0°F, but those are just guesses because we don’t have a thermometer in here.

Susan Steiner

Seems like I was just reading about your "lasts" before leaving McMurdo, and now here you are CAMPING in ANTARCTICA! wow...We are following your expedition up here in the mountains of Western North Carolina!

Jason Springs School

Have you encountered any wild life near Lake Joyce?

michael spring…

since you guys are in Antarctica and there is snow everywhere, why is there no snow in Lake Joyce camp. Is it summer over there?

Lucy Coleman

Susan – Thanks for following! I sometimes can't believe we made it to this point either. Thinking of you in N. Carolina....

Lucy Coleman

Jason –One of the things that makes this place so interesting scientifically is that there are no animals around to disrupt the microbes in the lake. If you go closer to the coast, you could see wildlife that is dependent on the oceans but we are a bit too far away from it where we are to see any life forms besides each other.

Lucy Coleman

Martin – Good question! It is very fun, and it's also challenging. If something doesn't go the way we want it to, we really need to be self-reliant and figure it out. It's a good confidence-building exercise, and having a good attitude about things really helps our team function well.

Lucy Coleman

Nuelle – We can't say that these microbial communities are the same because they are separated by billions of years of evolution. However, we are more interested in learning about the behaviors of these microbes, and if we learn about the behaviors of the modern microbes, we can better interpret the behaviors of microbes in the past.

Lucy Coleman

Samantha – We use a device called a jiffy drill, which creates a hole through the ice that is either 5 inches or 10 inches wide. We need to drill through the ice so we can see the microbes that live on the bottom of the lake.

Lucy Coleman

Hi Sunbonnet girls! You'd LOVE it here, but you can think of me while you bask in the warm sun – it sounds delightful! Good luck hunting pneumatophores! The microbialites here are nothing like the stromatolites of Glacier. These grow to a height of maybe ten inches, and form very different shapes, with webs and peaks. Very different, but very cool. It makes me happy to know you are following our expedition – thank you for that!! Can't wait for our next adventure. XO Lucy

Lucy Coleman

Michael –It is summer here… but that isn’t why there’s no snow where we are. We’re in a pretty unique part of the continent, where mountains block storm systems from depositing snow. Additionally, it's so dry here that any snow that falls is likely to sublimate, which means it turns from a solid to a gas without melting first. It appears to disappear over time.
