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.5441. The Arctic Great Rivers Observatory project studies the six largest rivers in the Arctic: the Mackenzie and Yukon Rivers in North America, and the Ob', Yenisey, Lena, and Kolyma Rivers in Russia. The research team are interested in understanding how climate change is impacting Arctic rivers. The team take measurements...

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...

Licensed Year(s): 2021 2021 2020 2019 2018
Summary: This licence has been issued for the scientific research application No.4934. The purpose of this study is to develop a method of characterizing the sensitivity and response of streams and rivers to regional variability in permafrost thaw in the Beaufort Delta Region, Western Canadian Arctic. All of the field team members are from within the NWT. This field program will follow the attached E...

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): 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: While data collected during the Environmental Impact Assessment studies (carried out in conjunction with the proposed construction and operation of the Mackenzie Gas Pipeline) are relatively comprehensive in describing the major physical-chemical features of the aquatic environment, they are lacking in the descriptions of the biological features of these environments, and as a consequence, their s...

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: As part of the Mackenzie Valley Gas Project, baseline aquatic studies in the Gwich’in Settlement Area (GSA) will continue in 2005. The work will include additional investigations into fish, hydrology and water quality in rivers and lakes previously visited, as well as summer and fall aquatics studies of waterbodies near the infrastructure sites, access roads, and borrow pits. All of the aquati...
