13 November, 1997First morning on the ice at Siple Dome came very quickly. The sun was up all night and must have been tired since I could not find it when I awoke. The clouds had come down instead to blanket the already white ice. The cloud that covered the ground is called fog both at home and here. You can make a type of fog if you breath on a real cold glass or on the car window when it is cold outside. The water vapor in the air forms clouds just like your breath on a cold glass. When it hits the earth we call if fog. I love to walk in the clouds at home, how about you? It was colder than I would have liked it to be (-18 degrees Celsius or -2 degrees Fahrenheit) but with my fur and nice clothes I was able to stay nice and warm. At the South Pole this morning the temperature was around -37 degrees Celsius or -34.6 degrees Fahrenheit. I was sure glad that I wasn't there. Humans here look real funny in the cold. The bundle up in great big red coats with hoods that have fur around them. They wear snow pants which they call wind pants and huge gloves and boots. They also mush wear things on their faces if on a snowmobile or in the wind. They look like giant red snowmen but they say they are warm. We did drive out to our work site and get it ready to start work in the morning all day long. In order to get there, we must drive a snowmobile and you often get covered in snow and hoar frost that falls from the sky because it is so cold. I looked more like a snowman after the ride out and back into camp. Because we were not able to do much this morning, I got to talk with Chris Shuman and Xin Chen who work at NASA Goddard Flight Center. They are studying how the ice moves in streams around Siple Dome. Siple Dome is a type of hill with over 1000 meters of ice beneath it. Around the Dome there are streams of ice just like streams of water that are moving from a higher area that has lots of snow on it. The streams are called A, B, C, and D. There may be more but I forgot!!!! Chris and Xin are studying Ice Stream D. It moves very rapidly in the center (sometimes over a 100 meters per year) and much slower on the edges (1 to 10 meters per year). Stream C does not move at all. They are going to set out flags on the ice stream and find out where they are located by a system called GPS. The GPS is the Global Positioning System and they use satellites to find out exactly where they are. GPS is the system used in cars to find where they are and are often used by people who hunt, fish, or just hike. They will leave the flags there for a whole year and then come back next year to see how far they have move. If you would like to find out more about Chris and his adventures try http://igloo.gsfc.nasa.gov/~shuman/home.html Something you may like to try similar to what Chris and Xin are doing is find a stream near your home and measure off two meters on the bank. Be careful around water that you do not fall in. You may want an adult to be with you. You will need a stop watch or a watch that has a second hand so that you can time something moving in the water. Place an object like a stick in the water at the first point that you measured and start you stop watch when it hits the water . Walk down the bank or have a friend with a second stop watch at the other end help time how long it took for the stick to get to the other end. If you divide the distance ( the length of the stream that you measured) by the time off your stop watch, you will have found the speed of the stream where the stick moved.Return to E.
