Our field work in northern Greenland during winter is nothing less than brutal. We arrive on heavy, military cargo planes or on small aircraft capable of landing directly on the sea ice. Most of the time, we sleep in unheated nylon tents in ambient air temperatures that drop to -30°C or lower in April. We use snowmobiles to travel across vast areas to look for signs of wolves, bringing cross-country skis as backup for use in areas where snowmobile use is not allowed by the authorities or to help us get home, if the snowmobiles break down or are lost. Some areas in North Greenland are so devoid of snow that walking is the only form of ground transportation feasible. The challenges are many: Fierce storms, frost bite, frost burns, mechanical breakdowns, immense distances, stuck or overturned snowmobiles or sledges, overflow (water on the sea ice), open leads, rough or impassable sea ice, early breakup, avalanches, polar bears, injuries, illness, and other hazards are daily facts of life. A speedy evacuation in case of an emergency is by no means a sure thing even in today’s world of satellite phones. We are completely on our own! Only the most prepared, competent, self-sufficient, and experienced individuals succeed in this environment.
