Licensed Year(s): 2024 2023 2022
Summary: This licence has been issued for the scientific research application No.5554. The objectives of this project are to improve the understanding of methane cycling in Mackenzie Delta lakes and how it is affected by the changing water levels and to decipher the impact of water level changes on the ability of the Mackenzie Delta to affect riverine carbon and nutrient flow to the ocean. Improve un...

Summary: This licence has been issued for the scientific research application No.5155. The objective of this project is to complete on ice snow depth, ice thickness and composition survey along with collection under ice core water quality information. Sample locations from previous years are located using a handheld GPS. On ice snow depth is measured using a tape measure. An ice auger is used to pene...

Summary: This licence has been issued for the scientific research application No.5057. The objectives include: 1) Creating a series of maps showing the thaw slump activity along the Beaufort Sea Coast near Tuktoyaktuk; 2) Developing detailed water, vegetation, and ground temperature maps of the study sites using drones; 3) Examining the effects of thaw slumping on the water quality of landscape-level r...

Licensed Year(s): 2019
Summary: This licence has been issued for the scientific research application No.4544. The objectives of this research are: 1) To investigate the environmental chemistry of the borrow pits and immediate surrounding areas to determine what, if any, environmental risk do the elevated concentrations represent; 2) To investigate the environmental chemistry of an undisturbed area around the Inuvik to Tukto...

Summary: The Objectives of this research are to: 1) Improve our understanding of microbial carbon-processing in Mackenzie Delta lakes and how it is affected by the changing water levels; and 2) Decipher the impact of water level changes on the ability of the Mackenzie Delta to affect riverine nutrient flow to the ocean. Specific activities for the coming field season include the following: (Goal 1) I...

Licensed Year(s): 2015
Summary: Thaw slumps are one of the most dramatic thermokarst features in permafrost regions. The number of thaw slumps on Banks Island has more than tripled in recent decades and it is likely that this change is altering terrestrial and aquatic ecosystems. This multidisciplinary research project investigates the short- (1960s-present day) and long-term (Medieval Warm Period to today) impacts of permafrost...

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...

Licensed Year(s): 2007 2006 2005 2004 2003
Summary: Project a: essentially fifth year of research (sixth-year if associated work in 2000 is counted), and seeks to continue heretofore successful investigations into the nature, substance and long-term effects of contact between Copper Inuit and Europeans/Eurocanadians in the 19th and 20th centuries utilizing sociocultural, archaeological, and economic methodologies, b. Project seeks to initiate a col...

Summary: The active layer, overlying the permafrost layer, is the surface earth material that thaws and re-freezes each year. Active layer thickness and character can influence hunting, fishing, forestry, gardening, transportation and construction. Changes in the active layer can contribute to landslides which may damage structures, hamper transportation, affect water quality, and influence surface and sub...

Licensed Year(s): 2005 2004 2003 2002
Summary: From 2001 to 2004, aquatics studies were done in the Niglintgak, Taglu and Parsons Lake lease areas and along the proposed gathering pipeline. In addition, aquatic studies at proposed infrastructure sites and borrow pits were initiated in 2004. The 2005 studies are a continuation of the work done in previous years. The work will include additional investigations into fish and fish habitat, hydrolo...
