Ecological and Geomorphological investigations in the alpine tundra of the Mackenzie Mountains, N.W.T.
Principal Investigator: Kershaw, G. Peter
Licenced 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 ...


Retrogressive Thaw Slides in the Richardson Range: Climate Change Indicator
Principal Investigator: Lacelle, Denis
Licenced Year(s): 2000
Summary: This is a study of retrogressive thaw sumps produced by the exposure and melting of massive ice in continuous permafrost (Richardson Range, NWT). These sumps are recently occurring and presumably a result of global climate change. This research will recognize retrogressive thaw slumps that have massive ice, identify the type of massive ice (glacier buried or segregated) and measure the rate of ...


Forestry Research in the Gwich'in Settlement Area
Principal Investigator: Walker-Larsen, Jennifer
Licenced Year(s): 2003 2002 2001 2000
Summary: Forest Fire Effects on Vegetation and Wildlife Habitat use: Research sites will be accessed by helicopter. Sites are located in burns of different ages. In the summer, small teams will complete vegetation plots, assess species composition and percent cover, and assess wildlife abundance. In the winter, helicopter track surveys will be completed. Forest Monitoring (ARNEWS and SI/MAB plots): The...


Sustainable Alternatives to Industrial Forestry in the Gwich'in Settlement Area
Principal Investigator: Anderson, David G
Licenced Year(s): 2000 1999 1998
Summary: The objective of this study is to develop a forest management plan that is sensitive to the priorities identified by the Gwich'in Elders and contemporary Gwich'in forest users. A total of four graduate students and their assistants will work with forestry experts employed by the Gwich'in Renewable Resources Board (GRRB) both to supplement an existing database and to synthesize the material into a...


Ground Ice Investigation
Principal Investigator: Moorman, Brian J
Licenced Year(s): 1998
Summary: The purpose of this research is to gain a better understanding of the origin, distribution properties of massive ground ice in the Mackenzie Delta. Knowing the size and shape of these bodies is one of the keys to determining how they form and how they will respond to climate change or terrain disturbance. The project would involve studying several sites where massive ground ice is present. The ai...


Morphological Study of the Campbell Dolomites Karst, Northwest Territories
Principal Investigator: McGuinness, Michaella
Licenced Year(s): 1998
Summary: The objective of this study is to document and gain a better understanding of the processes that formed the karst (solution-controlled) landforms of the Campbell Dolomites. The data to be collected includes descriptive data such as slope angles and aspect, composition, size , type and angularity of slope material and detailed surveying of the land. Transportation to and from the base camp will be...


Mass movements in the Aklavik Mountains and Water Quality in the Richardson Mountain Catchments
Principal Investigator: LAURIOL, Bernard
Licenced Year(s): 1998
Summary: The aim of the study of mass movements in the Richardson Mountains is to understand the processes of erosion related to climate changes. The site to be studied is located south of Little Fish Creek. The landscape looks like bench forms which are named Cryoplanation terrasses. This site was visited last year for 2-3 hours. Their formation are not really understood but we suspect that the melting of...


Vegetation Survey for the Ikhil Gas Development
Principal Investigator: Sutor, Greg
Licenced Year(s): 1997
Summary: Vegetation communities along the pipeline route and over other parts of the Project area would be provisionally mapped from aerial photographs. A field survey would be undertaken with an emphasis on identifying rare plants. The study area is in the Caribou Hills IBP site 4-9, which was in part proposed because of its rare flora. July is an optimum time for a single survey. Also transect sampling ...


Studies of the Environmental Effects of Disturbances in the Subarctic (SEEDS)
Principal Investigator: Kershaw, G. Peter
Licenced Year(s): 2000 1999 1998 1997 1996 1995 1994 1993 1992 1990
Summary: Access to the site will be along existing seismic lines from Tulita. Transport will involve helicopter, boat, ATV and foot. The research is planned to see what happens after the fire to the permafrost, soils, plants and animals. An unburned site will be monitored to provide comparison with the burned area. Many studies will be done, including measurements of air and soil temperatures, wind spe...


Ice scour disturbance and the structure of arctic marine benthic communities
Principal Investigator: Conlan, Kathleen E.
Licenced Year(s): 1994 1993 1992
Summary: The researchers will investigate the effect that sea ice has on shaping and scouring the sea bottom since these actions may play a major role in determining the sea bottom environment and the types of plants and animals that may live there. They will revisit the 1992 site in order to determine what new scours have appeared: those locations with fresh scrapes on the bottom will be monitored over t...
