Drivers and constraints of ecological change in the western Arctic
Principal Investigator: Lantz, Trevor C.
Licensed Year(s): 2022 2021 2019 2018 2017
Summary: This licence has been issued for the scientific research application No.5277. The objectives of this research are: 1) Use remote sensing (Landsat, QuickBird, InSAR, Airphotos, UAVs, etc.) to document regional landscape change (tundra fire, infrastructure, saline flooding, slumps, subsidence, vegetation change, lake drainage / expansion, etc.); and 2) Use field sampling and monitoring to determi...


A Multi-scale Assessment of Cumulative Impacts in the Northern Mackenzie Basin
Principal Investigator: Lantz, Trevor C.
Licensed Year(s): 2016 2015 2014 2013 2012
Summary: This project has three main objectives: Objective 1: To use satellite imagery (Landsat, QuickBird, InSAR, etc.) to document the rate and extent of landscape change (slumps, subsidence, vegetation change, etc.) in the northern Mackenzie Basin. To quantify landscape disturbances and vegetation regeneration patterns since 1985 Landsat satellite images will be obtained, that will provide refle...


Amendment - Hydro-ecological Responses of Arctic Tundra Lakes to Climate Change and Landscape Perturbation
Principal Investigator: Wrona, Frederick J
Licensed Year(s): 2011 2010 2009
Summary: The overall objective of this research is to improve our 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 research activities related to this research component dealing with fish. All other research activities related to this work were revi...


Long-term ecological and geomorphological investigations in the alpine tundra of the Mackenzie Mountains, NWT
Principal Investigator: Kershaw, G. Peter
Licensed Year(s): 2018 2017 2016 2015 2014 2012 2010 2009 2008 2007 2006 2005 2004 2003
Summary: Permafrost landforms are shrinking in response to climate warming. The researchers want to measure the amount of change each year and to measure the temperature of the permafrost year-round. In addition they want to measure the rate of plant recovery on disturbed areas resulting from the CANOL Project (1942-45). Access during the summer is via the Yukon along the Canol Road through Macmillan ...


Permafrost monitoring and collection of baseline terrain information in the Mackenzie Valley Corridor, NWT
Principal Investigator: Smith, Sharon S
Licensed Year(s): 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006
Summary: The objectives of this research are: • To provide baseline knowledge of permafrost and terrain conditions (specifically ground temperature and permafrost active layer thickness) and improve characterization of terrain sensitivity in the Mackenzie Valley. • Monitor ground temperature and active layer to detect changes in permafrost conditions resulting from surface disturbance or climate change a...


Environmental Studies Across Tree Line
Principal Investigator: Kokelj, Steven V
Licensed Year(s): 2012 2011 2010 2009 2008 2007 2006 2005
Summary: This licence is being issued for the scientific research application no. 978. The objectives of this research are to: 1) Monitor permafrost conditions in the Mackenzie Delta region; 2) examine freeze-back of the active layer and associated strength properties of freezing soil; 3) examine the influence of shrub removal on frozen ground and snow conditions at abandoned drilling-mud sumps; 4) inve...


Sensitivities of high-latitude lakes to climatic & development disturbances
Principal Investigator: Prowse, Terry D
Licensed Year(s): 2008 2007 2006 2005
Summary: Climate change in the Canadian Arctic is expected to have far-reaching impacts on the hydrology and ecology of freshwater ecosystems. These systems are particularly sensitive to climate change because many cryospheric and hydrologic processes respond to relatively small in changes in climate, which in turn affect landscape biogeochemical processes and associated ecological responses. Hence, the pu...


Permafrost and climate change, western Arctic Canada
Principal Investigator: Burn, Chris R
Licensed Year(s): 2022 2021 2020 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998
Summary: The researchers hope to measure ground temperatures to find out how they are changing as a result of climate change. They will try to find out how the thickness of the snow cover affects the amount of ground warming that has occurred over the past 35 years. The researchers will study the cracking of ice wedges to find out if they are cracking less now than they did in the 1970s and 1980s. The...


Surficial Geology Mapping Fort Norman (96C), Blackwater Lake (96B), Mahoney Lake (96F)
Principal Investigator: Duk-Rodkin, Alejandra ADR
Licensed Year(s): 2003
Summary: This project aims to obtain a better understanding of the sensitivity of slopes to disturbance from development, especially in the context of progressive climate warming. It will also identify baseline levels for natural and anthropogenic contaminants,...


Ecological and Geomorphological investigations in the alpine tundra of the Mackenzie Mountains, N.W.T.
Principal Investigator: Kershaw, G. Peter
Licensed Year(s): 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993
Summary: The main objectives of this study are to: 1. determine the status of permafrost land forms in the study area, and 2. determine the long-term recovery after abandonment of the CANOL No.1 project. Access during the summer is via the Yukon along the Canol Road through Macmillan Pass. Base camp is owned by Old Squaw Lodge at Camp 222. Beyond the base camp mountain bikes and foot will be the means ...
