Principal Investigator: Vieira, Gonçalo
Licensed Year(s): 2023
Summary: This licence has been issued for the scientific research application No. 5639. The goal of this research project is to better understand the characteristics of various different lakes, how their characteristics vary, as well as their potential relation to permafrost thaw events in the recent or distant past. The frequency of occurrence across space and time as well as the variability of: 1) opt...

Licensed Year(s): 2021
Summary: This licence has been issued for the scientific research application No.4966. The purpose of the proposed project is to improve the understanding of the effects of road development on lakes in Canada’s north. To achieve this purpose, the research team will pursue two objectives: 1) to determine if changes in water quality caused by road dust affects invertebrate communities (bugs and waterfleas...

Licensed Year(s): 2011 2010 2009
Summary: The overall objective of this study is to develop a model that can be used to look at the vulnerability of small arctic lakes and ponds to changing climate. Lake Ice Study: Lakes 5A, 5B and Noell Lake (MAP-2 of the original licence application) will be visited in mid-April to measure lake ice. Holes will be made in the ice using an ice corer. Ice thickness and composition will be determined by...

Summary: The overall objective of this research component is to improve the knowledge on present-day food webs/productivity in small Arctic pond/lake systems, in order to better predict changes that could occur under changing climate. The methodology described below pertains to all new research activities related to this new research component dealing with fish. All other research activities related to ...

Principal Investigator: Prowse, Terry D
Licensed Year(s): 2008 2007 2006 2005
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...

Principal Investigator: Douglas, Marianne
Licensed Year(s): 2002 2000 1999
Summary: The overall goal of the research is to more fully understand the present-day water quality of arctic lakes and ponds, and to attempt to determine if the water quality of these sites are changing as a result of, for example, recent climatic change or othe...

Principal Investigator: Lamoureux, Scott F
Licensed Year(s): 2001
Summary: The research will require fieldwork in the Richardson Mountains between 27 April and 8 May, 2001. Research will involve the development of a high-resolution paleoenvironmental record based on lake sediments from up to six lakes in the Richardson Mountains and the Melville Hills in the NWT. Transportation in the field for the Dempster Highway study will be by snowmobile and snowshoes. If snow cov...
