PurposeResearch
ObjectivesSignificant environmental changes are under way in the Arctic, in particular, a large reduction in sea ice extent and thickness, as well as increasing river discharge. Primary production in the Arctic Ocean is highly seasonal and highest on the shelf and at the receding ice edge. As the summer ice cover shrinks and river input increases, the physical and biogeochemical processes that control both the productivity and the structure of the marine ecosystems it supports are bound to be affected. Yet, our limited understanding of the factors that control the supply and cycling of organic carbon and essential nutrients in Arctic waters prevents us from predicting the longer term consequences of such changes. A better understanding of carbon and nutrient cycling, and their evolution in response to changes in ice cover and river discharge is clearly important to better predict the impact of climate change on the socio-economic sustainability of northern Canadians communities, the carbon sequestration capacity of the Arctic Ocean, and the addition of climatologically active gases (CO2, CH4, N2O, DMS) in the atmosphere. To this end, our proposal aims at: (i) elucidating the mode of addition, removal and cycling of key trace elements which act as micronutrients (Fe, Cu, Zn, Cd) or tracers of sources or processes (Al, Ba, Ga, Mn, Cr, Th, Pa) impacting the carbon and nutrient cycles in the Beaufort and Chukchi Sea (ii) using this information to elucidate the effect of climate change on the productivity, carbon sequestration and trace gas emission in the Arctic Ocean (iii) developing geochemical tracers that will provide a sedimentary record yielding insight into the past evolution of these processes in relation to past climate changes.
