NWT Streams and Rivers of the future: How permafrost thaw and groundwater activation are changing water resources (CIMP226)
Principal Investigator: Wright, Stephanie
Licensed Year(s): 2024 2023 2022
Summary: This licence has been issued for the scientific research application No.5294. The purpose of this study has four objectives: 1) Assess the spatial and temporal patterns of hydrologic change (groundwater and surface water) in the La Martre River and Trout River catchments (O1); 2) Identify the drivers, processes, and feedbacks responsible for the hydrologic changes identified in O1 and how they ...


Composition of natural dissolved organic carbon in streams along latitudinal transect
Principal Investigator: Turetsky, Merritt R.
Licensed Year(s): 2011
Summary: The goal of this research project is to measure the concentration and composition of natural dissolved organic carbon in rivers along a latitudinal transect from central Alberta to southern NWT. Data on water quality will be combined with spatial data that describes the drainage basins of the sampled rivers, e.g. ecosystem composition, size, slope, recent fire impact and permafrost conditions. The...


Active Layer Monitoring Network in the Mackenzie Valley
Principal Investigator: Nixon, Frederick M
Licensed Year(s): 2008 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993 1992 1991 1990
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...


Active layer moisture and carbon dynamics in the wetland-dominated zone of discontinuous permafrost
Principal Investigator: Schincariol, Robert A
Licensed Year(s): 2007
Summary: An improved understanding of the thaw and drainage processes, and exchanges of energy and moisture that control the flow of water in the vast wetland region of Canada is needed to improve weather and climate change predictions. Large-scale experiments on soils of the Central Mackenzie River basin will be used to elucidate moisture and carbon transport processes in the active layer. Laboratory base...


Implications of climatic change on water-based recreational activities in Nahanni and Jasper National Parks
Principal Investigator: Staple, Tamara
Licensed Year(s): 1993
Summary: The research in Nahanni National Park includes the setting up of programs to monitor water depth and vegetational changes along the river. Changes in water depth influence the ability of navigating the river, especially in areas of rapids, and has implications on the level of expertise required by visitors travelling the river. Monitoring vegetation along the river will provide information about...


Vegetation Response to Global Warming in the Mackenzie River Basin: Interations Between Northern Boreal Forests, Wetlands and Regional Hydrology
Principal Investigator: Nicholson, Barbara
Licensed Year(s): 1992
Summary: The Researcher will map the present distribution of boreal and subarctic wetlands in the Mackenzie River Basin. Wetland vegetation and water chemistry will be described for areas immediately surrounding permanent weather stations. The ecological relationships between climate, wetland water chemistry and wetland species distribution will be analyzed. A predictive indicator model will be built to pr...
