Global warming is already having a profound impact on Arctic climate. An observed consequence is the reduction of the annual ice cover at the periphery. The objective of this research program is to improve our understanding of the connections between the diminishing ice cover and the local ecosystems in the Canadian Arctic. We are particularly interested in the exchange of water between Beaufort Sea and Baffin Bay, through the Northwest Passage. We will also study some of the physical processes controlling the circulation and mixing in the region: eddies, upwelling and vertical convection at ice formation time.

全球变暖已经对北极气候产生了深远的影响。一个观察到的后果是减少每年的冰覆盖在周边地区。这项研究计划的目的是提高我们对加拿大北极地区冰盖减少与当地生态系统之间联系的理解。我们对博福特海和巴芬湾之间通过西北航道进行的水交换特别感兴趣。我们还将研究控制该地区环流和混合的一些物理过程：涡旋，上升流和成冰时的垂直对流。
