FRIDAY, September 30, 2011

Hi kids! Paglagivsignin! That means "We welcome you all!" in the native language of the Inupiat people of Barrow.

Barrow is 4 time zones behind the time zone of east Tennessee. When it is noon in Knoxville and you are getting ready to eat lunch, it is 8:00am in Barrow and I am just finishing my breakfast!

My internal alarm clock went off early this morning and I went for a walk. The sun had not risen and it was still dark. And what do you think I saw? A whale! Well, not one that was alive, but the jawbone of a whale. Bowhead whales are common in the Arctic Ocean and can often be seen off shore. The jawbone in the picture is from a whale that was almost 60 feet long and weighed 120,000 pounds. Even baby whales can be 10 feet long at birth and weigh 1,000 pounds.
Now that you know so much about the bowhead whale, it should be clear why high school students in Barrow are called the Whalers. The Whalers are just like any high school; they even play sports just like students at Karns. They play basketball and football. Their football field is not like the one at the Karns high school. Because of the harsh climate here in Barrow grass would never grow. So the Whalers have artificial turf that they roll out along the beach of the Arctic Ocean and play football with other schools in Alaska. Can you imagine doing this in Tennessee? And if that is not unusual enough, the field is blue! Do you know any other football teams who have a blue field? (Mrs. Roberts - the correct answer is Boise State University). Tonight the Whalers are playing an away game in Seward, Alaska. The Whalers have a winning record this year. I hope they win tonight!

Finally, I wanted to share a couple of pictures of the tundra and one showing where we stayed this week. Snow now covers the tundra and we had a great week in the Arctic. We learned about the ecosystems of Alaska; the plants and animals of the Arctic and how they cope with a harsh climate; and; and how kids in Barrow are a lot like those in Knoxville.

Have a fun weekend!

Mrs. Roberts - Are the students enjoying hearing about life in Alaska? I am having fun sharing my week with them. The world is a big place and there is so much to see! I am lucky that as a scientist I can visit these places and experience so many new things.

Researchers in our group continue to use special instruments to look at ice and soil below ground. Did you know that soil in the Arctic is frozen? You can dig a hole to roughly 15 inches before you hit solid ice. The instruments that we have can tell us where frozen soil is located and how deep it is. Students from the high school came today and watched us work for a while. One of our scientists talked to them and explained how some of our equipment works. They were very interested and surprised that we could "see" things buried deep in the ground.
We took a break this afternoon and drove around the town of Barrow. None of the streets are paved; all of them are dirt. Do you know why? Concrete streets like we have in Knoxville would crack and buckle in the cold environment of Barrow. Can you imagine the size of an Arctic pothole in the streets of Barrow?

In driving around town, we saw several interesting signs and paintings. These appear all around town; some are even painted on the sides of buildings. People in Barrow are proud of their town and emphasize that by putting colorful signs where people can easily see them. I like the one of the walrus; there are others of whales, seals, and polar bears. I still have not seen, however, a polar bear.
We also stopped along side the Arctic ocean. The water is cold and only the hardiest of animals can live there. Our group stood in the water for a few minutes. I have been to the coast in South Carolina and Florida, this is quite different. No one ever goes swimming in the Arctic ocean because it is just too cold. When you stand on the beach of the Arctic Ocean, the North Pole is still more than a thousand miles north. We live on a very, very big planet!
I will talk to you again tomorrow. I hope you are ready to hear about the local football team; the Whalers. I will also try to find a few surprises for you as well! Study hard and stay tuned...

WEDNESDAY, September 28, 2011

Yesterday was a great day to get an introduction to what it will be like to be a scientist in Barrow. We worked a long day in cold, windy, and snowy weather. Ground that was soft and spongy just a few days ago has now frozen. We walked on boardwalks and matted trail to protect fragile tundra, but were able to complete much of our sampling without any disturbance to the tundra. We collected soil samples and put them in small containers so we can analyze them later in the laboratory. We stored them in a cooler, but then found out that we had no refrigerator to get them cold. What do you think we did to keep them cold? Can you think like a scientist?

Scientists on our team are trying understand how land forms in the Arctic are controlled by things underground. Over the last few days we have used various imaging techniques, much like x-rays are used to image bones when they are broken, to see ice and frozen soils.
A third grade class from Ipalook Elementary School came to our research site to see what we were doing. They were a great group. They listened and then we showed them some of our equipment.

While the students were visiting us on the tundra we just happened to see a fox. We had seen many of these over the last few days. They are very curious animals. Can you see how the color of their fur helps them blend into the snow-covered tundra?

The students got back on the bus and we talked a little more about what it is like to live in Barrow. They liked their teachers and their school, although some of them liked the cold weather and others did not. Remember that I wrote about the mascot of the Ipalook Elementary school? Today I learned that the High Schoolers are called the Whalers; students at the middle school are the Wolves; and the mascot of the elementary school is the Arctic Fox! I ended my talk with the students by telling them that I was also writing to Mrs. Roberts' class of third graders in Knoxville. They all thought that was pretty neat. All the students here say "hello" and they wanted me to tell you that you are always welcome in Barrow. If you come, however, dress warm and be prepared for cold weather. The students also said to study your math, reading, and science!

A big "hello" to Mrs. Roberts and her third grade students at Karns Elementary school in Knoxville!

Here's an update of my trip so far...

Susan Hubbard and her team of scientists from Lawrence Berkeley National Laboratory arrived in Barrow on Saturday. They have been sorting gear, purchasing supplies, and have started to take a few initial measurements in the field. The weather has been cold and windy with some snow and freezing rain. Temperatures dipped into the twenties last night. These are typical conditions in Barrow for late September. Staying warm and dry will be our challenge this week!

Last night I checked into the dormitory-style housing that scientists use when in Barrow. There are three hotels in town, but those are almost always filled by tourists and oil company employees. Tourists come to see rare and endangered birds that live in the area and in hopes of spotting polar bears that come ashore from the Arctic ocean. Maybe I will see a polar bear this week! One did come ashore during my last visit and it created some excitement, with many local residents coming down to see the bear as it swam onto the beach. Because of its proximity to the National Petroleum Reserve, oil and natural gas exploration are also important activities in the Barrow area.

Our research team visited Barrow in August and had a photographer with us who took some really neat pictures. Wooden boardwalks are often used by scientists as they walk to and from their field sites in the tundra. These ecosystems are sensitive and damage due to repeated walking on the tundra can take years to recover. No vehicles are allowed on the tundra during the summer. In the winter, snow machines and other vehicles with big, spongy tires can be used on the tundra because the ground is frozen and covered by snow.

Although the Arctic tundra looks really different than the forests of eastern Tennessee, ecologists are finding that plants and animals in Alaska have many ways of coping with the extreme climate. Plants grow close to the surface of the ground, for example, to avoid the harsh influence of high wind and blowing snow. Animals like the snowy owl, fox, caribou, and reindeer also make their home in the tundra. Although it looks like a harsh environment, these animals get everything they need from the tundra.


1. You notice that there are no trees in the tundra. The nearest trees to Barrow are hundreds of miles to the south. Locate north, south, east, and west on a map of Alaska. What ocean is north of Barrow and what country is to the west?

2. Where do birds like the snowy owl live on the tundra and how do they stay safe from other animals?

3. Plants are adapted to the cold temperatures and short growing seasons in the Arctic. Animals are too. Can you think of ways that animals use to protect themselves in the winter?

This week our team travels to Barrow, Alaska. Scientists from the Lawrence Berkeley and Oak Ridge National Laboratories in California and Tennessee, respectively, are conducting research to better understand processes that form polygonal ground in tundra ecosystems. Thousands of square miles in the Arctic are covered by networks of polygons that fill with water early in the year after the snow melts. Polygons are formed by a well-developed system of ice wedges in the ground and are a striking feature of the landscape, particularly when seen from the air. This is just one of many examples where nature creates intricate designs on the earth's surface. Although a common landform in the cold regions of the world, polygons are sensitive to disturbance and warming temperatures, and scientists want to know why.

Our team will also be sharing our experiences in Barrow this week with Mrs. Roberts and her third grade class of students at Karns Elementary School in Knoxville, Tennessee. Students in Mrs. Roberts’ class are learning about ecosystems, climate, and landforms around the world and our week in Barrow will provide a good opportunity to highlight all of this, and more. We are looking forward to daily postings to this site and with sharing thoughts and pictures with students while in the Arctic.
Today (Monday) is a travel day; a long one. I leave Knoxville, travel to Chicago, Seattle, Anchorage, and then after flying for more than 16 hours and traveling almost 4100 miles, I will land in the small city of Barrow. Barrow is the northernmost city in the United States and it sits right on the Arctic Ocean. It is 320 miles north of the Arctic Circle. Barrow is home to 4600 residents, many of who are Native Inupiat Eskimo people. I have visited Barrow several times in the last year and like the town and people. It is, however, remote; you can only reach Barrow by airplane or boat. You cannot drive to Barrow from other cities in Alaska. So it is very different than living in Tennessee. The record low temperature for Barrow is -58 degree Fahrenheit. Because it is so far north, the sun never rises above the horizon between mid-November and mid-January. This 2-month period is known as polar night. Snow machines are the best way to get around in the winter. I will share more facts about Barrow later in the week. Wait until you hear about the Barrow High School Football Team – the Whalers!

1. Find Alaska, and then Barrow, on a map of the North American Continent. Can you determine the location of Barrow by its latitude and longitude?

2. Locate the Arctic Ocean. See if you can also find the Arctic Circle on the map or better yet, a globe of the Earth. Compare it to the Equator.

First geophysical field campaign!

The NGEE geophysical team had their first field day today, with an objective to explore subsurface soil variability just prior to freeze in a field site in Barrow that displays different thermokarst characteristics. Baptiste Dafflon, Craig Ulrich, John Peterson and Susan Hubbard from LBNL were joined by Alessio Gusmeroli from UAF. We arrived to a dusting of snow and what seems like an incipient freeze – everyone was bundled for field work. After hauling lots of equipment out to the site, we collected surface electromagnetic data along some key transects and tested the ground penetrating radar responses. We initiated the collection of active layer depth, temperature, and TDR moisture probing along the geophysical transects. Tomorrow Stan Wullschleger from ORNL will join us, and we will start the electrical data acquisition. We are exciting to see what these data yield!
