| Résumé | (disponible en anglais seulement)
New motivation and significant funding for geological study of the Arctic Basin is being driven by a fascinating marriage of international politics and science
under the United Nations Convention on the Law of the Sea. Canada has a sovereign interest, under Article 76 of the Convention, to define an Extended Continental Shelf along the Arctic margin offshore of Banks and Prince Patrick islands. Researchers
have long desired to collect the first seismic data in this region in order to better understand its geological evolution, but the vast Arctic icepack poses formidable technical challenges. Efforts mounted since 2005 by the Geological Survey of
Canada have culminated in the succesful development of a seismic system capable of reliable operation from icebreakers in polar icepack regions. The system was used in 2007 and 2008 to collect nearly 6000 km of high quality data. This ongoing program
is but a recent example of the long tradition of collaboration amongst researchers from several countries to explore the frontiers of science. The United Nations Convention on the Law of the Sea is a noteworthy human achievement that codifies mutual
benefits between the international scientific and political realms. |
