ALISON (Image 3) A group of home-school students at the Aurora Pond observatory site in Fairbanks, Alaska. In the foreground are two parents taking snow samples that will be weighed and their density determined. In the background, children measure snow depth and temperature. Note the line of stakes that marks the measurement transect. The site is part of the ALISON (Alaska Lake Ice and Snow Observatory Network) program, a science education and scientific research partnership between the University of Alaska, Fairbanks, and the K-12 education community in Alaska. Aurora Pond is located in the Aurora subdivision of Fairbanks, Alaska. Situated by the Johansen Expressway, the pond is actually a gravel pit that flooded after highway construction. It is about 200 meters by 200 meters in size and the water depth varied between 9.3 meters and 17.66 meters beneath the ice along the 100 meter measurement transect used in 2001-2002. Measurements taken at the observatory will be used for numerical modeling to simulate the variability of lake ice growth and decay at the present time and during the period of meteorological record in the different climate zones of Alaska, and to understand the factors responsible for that variability in order to predict the response of the ice to future climate change. This research was supported by National Science Foundation Office of Polar Programs grant OPP 03-26631. (Date of Image: February 2004) [One of 8 related images. See Next Image.]
