About McMurdo Station

I've spent the past couple of days at McMurdo Station setting up our lab and prepping for the field. McMurdo is the largest of the three U.S. research stations in Antarctica. (We also have Palmer Station on the peninsula and one at the South Pole. Also, there are two icebreakers that cruise the Southern Ocean for marine research.)In addition to the three U.S. bases, the U.K. bases are also labeled on this map. There are, of course, many bases owned by other countries across the continent that are not labeled on this map.

McMurdo Station sits on Ross Island in the Ross Sea, at the bottom-center of the above map. (The area is named after James Ross, the earliest explorer to reach land in this area of Antarctica in the mid 1800's.) If we zoom in on the McMurdo area, you can see that, while I am here at McMurdo Station (the red dot), I'm not actually on the mainland of the Antarctic continent. We are, however, on the edge of the permanent ice shelf, an area of the Ross Sea that is frozen on top year-round, so it is frequently considered to be part of the continent. That's why it's shaded a different color in the first map. Below Ross Island (to the north), the Ross Sea is also frequently ice-covered, but it melts back, sometimes as far as McMurdo Station, during the summer months. In the map above, you can see how some of that ice is breaking apart around the island. It is called "sea ice", not the "ice shelf", because it is a different piece of ice than the permanent stuff that makes up the ice shelf.

Also on Ross Island is Mount Erebus: the southern-most active volcano in the world. (The volcano is named after James Ross's ship, The Erebus.) In the second map, Erebus is the black-tipped cone on the right side of the island. Mt. Erebus is always looming in the background here at McMurdo. This is what it looks like from the ground while standing on the ice shelf near McMurdo Station:
In this photo, Erebus is pretty quiet. Some days we see it puffing smoke quite a bit.

Here's an aerial view of McMurdo Station:
McMurdo and the other U.S. research stations on Antarctica are funded and managed by the National Science Foundation. Research here has been going steady since 1956. Contractors and the U.S. military provide the support to operate the bases and make the scientific research possible. Some of the research is to understand the Antarctic region and ecosystems, as well as the region's response to changes in climate. This includes studying glaciers, geology, soils, and oceans. People study the chemistry, physics, and biology of all of those components. Also, Antarctica is the home to a lot of atmospheric and space research, because the atmosphere is thinner here than other parts of the planet. That means that there are a lot of scientists at McMurdo studying a wide variety of topics, plus enlisted military and contracted support staff (usually adventure-seekers). During the summer season (right now), the total number on base is over 1,000 diverse people. You never know what kind of conversation you'll have when you sit down for dinner!

I have two more days to get myself prepared for my field work. On Monday, I should be heading to the Dry Valleys, which are across the McMurdo Sound on the mainland of the continent. Where I'll be heading is labeled with the orange dot on the second map.

Arrival in McMurdo

I have arrived at McMurdo Station, Antarctica!

Today, I woke up early in Christchurch, packed my bags and headed to the airport. There, I boarded a U.S. Air Force C-17 and flew from New Zealand to Antarctica. It's about a 5-hour flight. There was a big crowd on the plane this year: about 60 people. Only half of us were American. We flew down with a lot of Italian and French scientists who headed to their own bases after they arrived at McMurdo.


The runway that we landed on is built on the seasonal sea ice, so it is called the "ice runway". It's rebuilt each year and used until early or mid-December when the ice starts to break up. In my previous years, I've always arrived after the ice runway has been closed, and have landed instead at Pegasus Airfield, located further back on the permanent ice shelf. So, it was a different landing for me this year! The ice runway is much closer to McMurdo Station, so the journey from the plane to the station was much shorter than I'm used to. You can even see the ice runway clearly from our lab window:
Tonight I'll be getting settled into my room and lab. Tomorrow, I begin the preparations for getting out into the field to get my work done. It'll be good to revisit all of the people that help me do that!

Gearing Up

Today I went to the U.S. Antarctic Program office in Christchurch to be outfitted for gear I will need in Antarctica. I wear a lot of my own personal clothes and gear, but I also use a lot of special issued gear. The board in the picture shows the variety of clothes they give us: everything from long underwear and socks to coats and hats. We have to try on all of the clothes to make sure they fit.


Because Antarctica is very cold, we have three layers of clothes for warmth. We wear polypro long underwear pants and shirts , and then two layers of fleece. On top of the warm clothes, we have a wind-proof layer of overall pants. Here you can see me wearing my long underwear shirt and pants, topped by my wind pants.The boots I'm wearing are called "bunny boots". They are very insulated and water-proof to make sure our feet stay warm and dry. The insulation makes these boots very bulky and heavy, so walking in them can become hard!

On top of everything, we wear a down parka with a fur-lined hood. The giant red parkas is nicknamed "Big Red". There is a also a light-weight, red wind-breaker, which is called "Little Red". Big Red is very warm, but it is very large and bulky. Unless it's very cold, I prefer to wear Little Red for my field work.


Once we have picked out all of our clothes, we pack everything into the two orange duffel bags. Those two bags contain all of the gear and clothing we will use for the next two months!

Our flight to Antarctica is scheduled for very early tomorrow morning. We have to leave the hotel by 6 A.M. Let's hope the weather over McMurdo stays good so that we can get out of here on time!

In Christchurch, New Zealand

I have landed safely in Christchurch, New Zealand. This marks the end of the first portion of the journey. I will spend a couple days here getting prepared (and enjoying some summer weather) before I head down to McMurdo.

Check out this photo I took as we were flying over New Zealand near Christchurch. It's a beautiful country!


The river that you see running through the middle is called a "braided river". It's a series of smaller channels of water that twist together and are separated by sand bars. This type of river is found in areas where the ground is easily eroded to create a lot of sediment (which creates the sand bars) and where there are rapid changes in the amount of water flowing in the river. The mountains in the background are geologically young, and easily erode to create that sediment.

Braided rivers are common here in New Zealand, but also in Antarctica. Here's a photo I took a few years ago when I was flying over the Onyx River in the McMurdo Dry Valleys of Antarctica, where you see the same braided pattern:


(You'll notice one thing unique about Antarctica: there are no trees, roads, or houses to give you a sense of size, like you have in the New Zealand photo. This photo was taken from a helicopter pretty high up, but you wouldn't know that if I didn't tell you!)

And I'm off to Antarctica!

I'm about to head to the Phoenix airport to begin my journey towards McMurdo Station, Antarctica. First, I'll fly commercially to Christchurch, New Zealand. I have a short hop from Phoenix to Los Angeles, followed by a very long flight to Auckland, New Zealand and another short hop to Christchurch, New Zealand. It'll take a total of 24 hours from the time I leave my home in Phoenix until I arrive in Christchurch, but because of the International Date Line, I'll land there 2 days later.


Check out this interactive map if you want to find out more about my travel plans.

I'll be in Christchurch, NZ for 2 days before I finish the trip and fly to McMurdo Station in Antarctica. While in Christchurch, I'll get fitted for all of my Extreme Cold Weather gear, receive some safety training, and of course enjoy some of that great New Zealand summer weather!

Let's hope the weather is good for our travels and that we don't encounter any major delays! The next time I post, it'll be from Christchurch, NZ!

Getting packed to leave the U.S.

My departure for Antarctica is approaching quickly! I leave for Antarctica on December 3. I'm finishing all of the work that needs to be done at ASU before I leave and getting my personal gear packed up.

Here's my partially-packed suit case. There are normal things in there that everyone packs when they travel: clothes, socks, and shoes. You can see that there aren't a whole lot of clothes. Really, there's just one stack of pants and shirts. We aren't able to bring down a lot of stuff, even though we're there for a long time. I only bring down a few pairs of pants and a couple of shirts, but several sets of under-layer clothes (like long johns and undershirts). Most of the clothes in the stack are fleece, silk, or polypro for warmth. I don't have to pack pajamas, because I always sleep in my long johns. I also pack lots and lots of warm socks. I can tolerate wearing dirty pants and shirts when I'm in the field, but dry socks are like gold! You can see thick socks crammed in all of the corners of the suitcase. (My grandmother has given me most of those socks over many Christmases.) And of course I pack hats, mittens, and hand warmers (just a few, for those really, really cold moments). I also always pack sandals. Those are handy for when you come inside after being out in the field and you want to take off your giant boots and let your feet air out. In the lid of the suitcase there are also some books to read and my notebooks from previous years on the ice. In the small pocket I have things like my camera, batteries and the charger, and my iPod. There's a Christmas present in the suitcase, too. I will be at one of the field camps for Christmas, and every year we play the "gift game". There's something good inside the gift I'm putting in...

The red backpack will be my carry-on during the flight. It has all of my toiletries as well as some warm-weather clothes for my time in New Zealand. I carry all of that stuff on the plane so that, if my luggage gets lost, I can still take a shower and put on clean clothes after the long flight across the Pacific! It also has my passport and other travel documents so that I can get into New Zealand.

There are still a few things that need to be packed. I have to include my eyeglasses, sunglasses, underwear, and other things I'm still using at home. I'll finish packing tonight and tomorrow morning, then I'm off to the airport! Let me know if you notice anything important missing from the suitcase, so that I can make sure to pack it before I go.

Welcome to Season 4!

Welcome to another field season of research in Antarctica with the polar soils research group!

I am making preparations to leave the U.S. and head to McMurdo Station on December 3. It is a busy time of preparations for me! I have a lot of work to finish up, travel plans to arrange, and supplies and equipment to gather. One big difference from the past three seasons is that I am now based at Arizona State University, so I am far away from my fellow teammates at Dartmouth College. That makes preparations a bit more complicated. But, in just a couple weeks, I'll be on my way.

If you are new to the Polar Soils blog, here is some information that might be useful to you:

Where we go:
When most people think of Antarctica, they think of ice. When you're on the continent of Antarctica, it's referred to as being on the "ice." However, the area we study is a polar desert called the McMurdo Dry Valleys, where the glaciers have retreated. Just like deserts in the U.S., such as the Sonoran Desert where I now live, there's very little precipitation, so there's actually bare soil, not just ice and snow! The red dot on the map shows where McMurdo is located:

What we do:
Our research is in the field of soil biogeochemistry, which is just a big word that means we study the way nutrient elements move in the soil. We are especially interested in carbon, nitrogen, and phosphorus, since these three elements are so important for all forms of life. We study how the living organisms influence nutrients in the soil. All of the animals in the dry valleys are microscopic (except for the scientists, of course). While other areas of Antarctica have penguins and seals, the dry valleys' largest animal is a nematode. A predatory nematode is the top of our foodchain- the equivalent to a lion in the Serengeti! We also study the mosses growing in the dry valley soil. Mosses are the only plants growing in the dry valleys and the only living things you'll find above the soil- the equivalent to the redwood forests in America!

Who we are:
Our research team is a little bit different from last year. There are four soil scientists going to Antarctica from Dartmouth. The leader is Dr. Ross Virginia, a professor at Dartmouth who has been going to Antarctica for many years. Also on the team are me (Becky, a professor at Arizona State University), Jenn (a graduate student at Dartmouth College), and Mike (a professor at Indiana University of Pennsylvania).

While on the ice, we will continue to work very closely with another group of scientists from Colorado State University led by Dr. Diana Wall that specializes in the nematodes (they have a special nematode blog). Together, all of us study the nutrients and biology of the McMurdo Dry Valley soils.

About the blog:
Our blog is designed to be an educational tool for elementary and middle school classrooms, but all readers are welcome to follow along! Teachers interested in using the blog in their classes are welcome to contact me (contact information available through my website, listed under my Profile on the bottom-right).
On the right-hand side, there are some links with additional information that is useful for both kids and adults. Many links are added throughout the season, so keep an eye on them!
