an Inuvialuit community located on the shores of the Beaufort Sea, east of the Mackenzie Delta, at 69°27N, 133°05W, and it is the most northern com-munity on mainland Canada. The population was esti-mated at 979 in 2000, with approximately 88 % of the population being Inuvialuit. The community has tra-ditionally developed along this narrow spit of land reaching out into the Arctic Ocean providing open ocean on one side, and a sheltered harbour on the other side (Fig. 1). The Hamlet of Tuktoyaktuk has a mean annual tem-perature of 10°C, with a mean summer temperature of 4°C, and the mean winter temperature is 29°C. The ocean freezes in late October, and the ice breaks up in late June. The tidal variation in the area ranges from 35 to 60 centimetres on average.
