Summary

The Arctic Ocean is a vital component for survival of life in the Canadian Arctic. It controls weather and moderates climate, and Arctic food webs are linked to the productivity of polar waters. Marine mammals and fishes can serve as indicator species for arctic environmental health but little is known about their movements and interactions and the influence of the environment. This research will use existing and novel tagging technology to examine large-scale marine migration of key arctic fish and marine mammal species, their local movement in coastal waters, stock mixing as ice patterns change, and zoogeography relative to fossil fuel exploration and future shipping activities. Such research is critical in the face of current and forecasted changes to climate and ice conditions.
