Sensitivities of high-latitude lakes to climatic & development disturbances
chercheur principal:
Année(s) de permis: 2008 2007 2006 2005
Résumé: 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...

IPY-SCARF: International Polar Year - Study of Canadian Arctic River-delta Fluxes
chercheur principal:
Année(s) de permis: 2008 2007
Résumé: The Arctic Ocean receives much higher river inflows than other ocean basins and this has major implications for sea-ice formation, for nutrient supply to the base of aquatic marine foodwebs, and for optical properties of ice-free areas and ice-pack margins via fluxes of dissolved organic matter and riverine particles. The Beaufort Shelf is strongly influenced by Mackenzie River outflows. However, ...

2006 - 2007 Biophysical and Reconnaissance Studies in the Gwich’in Settlement Area
chercheur principal:
Année(s) de permis: 2007
Résumé: Several biophysical and engineering studies on the feasibility of a pipeline in the Mackenzie Valley have been conducted, and will continue in 2007. Local knowledge, scientific research, and existing technical information are being used to develop a knowledge base for environmental protection plans, engineering design and regulatory processes. Route and site reconnaissance will be by helicopte...
