T02. Arctic Canada Geosciences from Land to Sea: Climate, Tectonics and Sedimentation
Patrick Lajeunesse (UniversitÃ© Laval, Canada)
Thomas Lakeman (Dalhousie University, Canada)
This interdisciplinary session aims at bringing together Arctic geoscientists who characterize the geology and geomorphology of Arctic Canada in order to understand its evolution in relation to climate, tectonics and surface processes on different space and time scales. We are seeking papers documenting how Arctic basin dynamics relate to on land processes and boundary conditions. In this respect we welcome contributions from marine, lacustrine and terrestrial environments in the Canadian Arctic and adjacent regions on geodynamics, tectonics, erosion and sedimentation, glacial geology and geomorphology, paleoclimatology, paleoceanography, hydrogeology, natural hazards, natural resources, sediment fluxes, sea level change, permafrost or coastal dynamics.
T03. Arctic Ecosystems as Sources and Sinks of Greenhouse Gases: Analysis at Multiple Scales
Neal Scott (Department of Geography, Queenâ€™s University, Canada)
Howard Epstein (Department of Environmental Sciences University of Virginia, Unites States)
Paul Treitz (Department of Geography, Queenâ€™s University, Canada)
Arctic ecosystems play a significant role in the global carbon cycle, and changes in climate regimes could influence net exchange of other greenhouse gases. Changes in the climate system are becoming apparent in some parts of the Arctic, and are predicted to continue into the future. Controls over net greenhouse gas exchange occur at various scales, including impacts of soil moisture on soil microbes, changes in vegetation distribution, permafrost thawing, and landscape disturbance. To predict how these changes may influence climate in the future, it is important to understand key processes that regulate greenhouse gas exchange, and the ability to quantify relevant ecosystem properties over various spatial scales. This session will bring together scientists working to understand both critical processes controlling net greenhouse gas exchange in Arctic ecosystems at fine scales, but also those developing better techniques to quantify ecosystem properties such as soil moisture regimes and vegetation distribution that influence net greenhouse gas exchange. Bringing these two groups together should help identify the key biophysical variables needed to predict future changes in net greenhouse gas exchange, but also highlight the potential for tools such as remote sensing to provide these biophysical variables, and associated uncertainty, over various spatial scales. Results from this session will not only contribute to improved understanding of the current greenhouse gas balance of Arctic systems, but also improve predictions under future climate.
T04. Education in Inuit Nunangat in a time of change
Lars Kullerud (University of the Arctic, Norway)
Mary Simon (National Committee on Inuit Education, Canada)
Thierry Rodon (UniversitÃ© Laval, Canada)
The National Committee on Inuit Education (NCIE) final report (2012) was a rare achievement in Canadian politics and public policy: it was an Inuit initiative that led to consensus among federal, territorial, provincial and Inuit jurisdictions on a crucial matter of shared responsibility. Since the publication of the report, the Amaujaq Centre for Inuit Education has been formed, Nunavut Minister of Education Paul Quassa has secured partial private sector funding for a university in Nunavut. Acknowledging these achievements, this session will focus on the future. As the NCIE pointed out, a strong, resilient, effectively bicultural education system, suited to the Inuit societies it will serve, is essential for sustainable development in Inuit Nunangat. What steps must now be taken by Inuit organizations and governments, and by other Canadian governments, to bring this about?
The first part of the session, will be open for the presentation of papers on Arctic education. The second part will be led by the Amajauq center for inuit education to engage a dialogue on future directions in inuit education research. Finally the session will close with a panel including Inuit leaders in the field of education and Arctic education researchers.
T05. Arctic Ocean Acidification
Richard Bellerby (Norwegian Institute for Water Research, Norway)
Jeremy Mathis (National Oceanic and Atmospheric Administration -NOAA, United States)
Jan RenÃ© Larsen (Arctic Monitoring and Assessment Programme - AMAP, Norway)
The proposed session is dedicated to â€œMonitoring, Modeling and Predicting Circumpolar and Regional Arctic Systemsâ€
