Project Description: The researchers hope to measure ground temperatures to find out how they are changing as a result of climate change. They will try to find out how the thickness of the snow cover affects the amount of ground warming that has occurred over the past 35 years. The researchers will study the cracking of ice wedges to find out if they are cracking less now than they did in the 1970s and 1980s. The researchers will travel to Illisarvik and Garry Island by snow machine and helicopter, and to Herschel Island by Twin Otter. They will travel to Paulatuk by Aklak Air. At each site they will conduct surveys with levelling equipment, and measure ground temperatures with data loggers and on thermistor cables. In the winter the researchers measure snow depths by probing, and lake-ice thickness by drilling a hole. They determine if ice-wedges have cracked by recording circuits of breaking cables. The camps are located at Garry Island and Illisarvik, have only a few people, and are self-contained. The study will be conducted at: Garry Island 69 29.78 N 135 45.41 W Illisarvik 69 28.78 N 134 35.59 W Air Temperature Stations: Red Lake 68 44.88 N 134 15.46 W Bar C 69 02.21 N 134 38.75 W Seal Lake 69 12.19 N 134 41.67 W Dennis Lagoon 69 21.69 N 134 41.80 W
