Résumé(disponible en anglais seulement)
Over the past few years, interest in the Canadian Arctic has greatly increased and news stories about the region are appearing on an almost daily basis in the worldwide media. Topics garnering public attention include climate change, oil and gas exploration, international boundary disputes, sovereignty issues, and security concerns. The Arctic is also at the forefront of Canadian politics as northern research was discussed extensively in the Speech from the Throne on October 16, 2007. This speech relayed the Canadian government's commitment to addressing northern issues through an increased Canadian presence in the Arctic, scientific research, and improved infrastructure.
New Canadian interest in the Arctic is a step in the right direction to improve the country's knowledge of the north, however working in the Arctic is much different than working in the rest of Canada. Sea ice covers the waterways of the Canadian Arctic for most of the year but there is also considerable seasonal variability of the ice cover, making the prediction of ice cover difficult. It is mostly dark in the Arctic for the months of November through to February with average winter temperatures of -37° C and extreme lows of -62° C. Poor weather and visibility during the winter makes air travel unreliable while shipping of supplies and equipment is time consuming and expensive. Some areas of the Arctic are only accessible by road during the winter months when ice roads allow shipping of items that are too large to be carried by aircraft. Overtaxed or non-existent logistical support also contributes to the increased time and money required to work in the Arctic.
Even with all of these impeding factors, BIO researchers conduct successful field work in the Arctic every year. Two ongoing projects provide important data to support marine geoscience research relating to seabed geohazards, coastal erosion, and continental shelf mapping. These are the Geoscience for Ocean Management program run by NRCan and the United Nations Convention on the Law of the Sea (UNCLOS) program run jointly by the Department of Foreign Affairs and International Trade, Canadian Hydrographic Service (DFO), and the Geological Survey of Canada (NRCan).
