Summary: The Circumpolar Flaw Lead (CFL) system study is designed to examine the importance of climate processes in changing the nature of a flaw lead system and the Arctic marine environment in the Northern Hemisphere, and the effect these changes will have on the marine ecosystem, contaminant transport, carbon fluxes, and greenhouse gases. Using the Canadian Research Icebreaker (CCGS Amundsen), the team ...

Summary: The objective of this study is to develop a hydro-ecological model for small Arctic lakes to assess the vulnerability of their ecosystems to disturbances, such as climate change or water withdrawal. To quantify geochemical loadings to lakes, a model is being developed by monitoring lakes and their contributing catchment (surface water flow). A climate station will be set up at 2 - 6 sites to mo...

Summary: The goal of this study is to collect lake sediment cores from shallow lakes to quantify the impact of past climate change on the vegetation and lakes of the area. Sediment cores from the bottom of 2 lakes in the region will be collected. A 10 day camp of 3 people will be set up at 71°43'12"N, 122°02'31"W. Transportation will be by Twin Otter to the camp, and by walking to the lakes. No gas powe...

Summary: The goal of this project is to collect sediment cores and water samples from a lake, to be analysed as an indication of past snow melt and stream flow in the area. Two personnel will camp at the site for 5 days in late May. In late June, early July and/or late August they will return by helicopter from a neighboring camp in Nunavut for two or three visits, 3-4 hours each visit. A skidoo will be...

Summary: The purpose of this study is to investigate how might climate change-related risks be better integrated into disaster management (prevention, preparedness, response, recovery) legislation, agreements, policies and planning, especially in relation to risk management of built infrastructure in the Canadian North. The Project Team will conduct regional/local stakeholder engagement sessions in thre...

Summary: The objectives of this project are: 1. Assess the present and future adequacy of surveillance tools to support northern managers’ ability to identify and monitor acute and chronic diseases, exposures, and other health determinants related to climate change and economic development impacts. 2. Assess the applicability and use among northern managers of current risk management frameworks (RMF), wh...

Summary: The active layer is the earth overlying permafrost that thaws from the surface and re-freezes each year, and it responds to climate change. Active layer thickness influences vegetation and soil conditions, potentially influencing hunting, forestry, etc. and it’s, thickness, texture and moisture content affects foundations. Changes in the active layer and thaw depth can contribute to slope instabil...

Summary: The impact of climate change on forest ecosystems in the Mackenzie Delta is being studied using dendrochronology. Earlier studies indicate a negative relationship between tree growth and summer temperatures. Summer temperatures may be exceeding the physiological threshold of northern trees or perhaps the trees are drought stressed. Manual and automatic dendrometers will be used to measure tree gro...

Summary: This project will partner with the community of Ulukhaktok and involve community youth as researchers to develop an understanding of how social change and climate change interact to affect the functioning and well-being of arctic communities, specifically for younger generation community members. The research methods in this study will be applied via an open and evolving process directed in col...

Summary: The Mackenzie Delta is sensitive to both climate warming and human development. This project will contribute to a better understanding of ground temperatures in the Mackenzie Delta and will provide a baseline from which to assess future changes and cumulative impacts. Ground temperatures will be collected from the southern, central and outer delta regions. In the summer, about 30 boreholes (l...
