Synchrotron investigations at the CLS
Principal Investigator: Laroque, Colin P
Licensed Year(s): 2018
Summary: The goal of this project is to determine arsenic toxicity in the environment through time by using trees and soils from the area surrounding the Giant Mine. This will be done using synchrotron techniques to determine the intensity of toxicity in each year since the contamination started. A 5.1 mm tree borer will be used to take 2 cores from trees within a close proximity to Giant Mine. The res...

Long-term ecological and geomorphological investigations in the alpine tundra of the Mackenzie Mountains, N.W.T.
Principal Investigator: Kershaw, G. Peter
Licensed Year(s): 2018 2017 2016 2015 2014 2012 2010 2009 2008 2007 2006 2005 2004 2003
Summary: This study is to monitor the environmental impacts of disturbances caused by the Canol Project and to measure the effects on permafrost of climate change. The Canol disturbance studies have been underway since the late 1970's and the permafrost studies since 1990. This is year 15 of a 20-year study. Access during the summer is via the Yukon along the Canol Road through Macmillan Pass. Beyond...

Mackenzie Valley Landslide Geotechnical Investigations
Principal Investigator: Nichol, Susan L.
Licensed Year(s): 2005
Summary: The objective is to improve knowledge about landslides in the Mackenzie Valley. The results of this study will enable better environmental impact assessments and help to reduce environmental impacts related to the construction and operation of the proposed Mackenzie Valley pipeline. As well, the results will have a broader application to a wide range of future development activities in the region....

Sustainable Alternatives to Industrial Forestry in the Gwich'in Settlement Area
Principal Investigator: Anderson, David G
Licensed Year(s): 2000 1999 1998
Summary: The Gwich'in Renewable Resource Board (GRRB) is working with the Department of Resources, Wildlife and Economic Development (DRWED) and Gwich'in Tribal Council (GTC) to develop a forest management plan for the Gwich'in Settlement Area. In order to manage the forests sustainably, we must have a good understanding of how fast trees grow and how forests regenerate after disturbances (particularly wi...

Derivation and Analysis of Climatic Information from Tree Rings
Principal Investigator: Jacoby, Gordon C.
Licensed Year(s): 1994 1989
Summary: The researcher will take 5 mm diameter increment core samples from old-aged trees growing near the tree line. This sampling is not harmful to the trees. At two sites the researcher will sample about 10 trees. The samples are processed to produce ring-width and wood- density data for each annual ring. This data will then be statistically compared to meteorological data to make estimates of past cl...

Jack Pine Forest Research
Principal Investigator: Osawa, Akira
Licensed Year(s): 1994
Summary: The researcher will conduct research on jack pine forests along the highways in Wood Buffalo National Park and will also collect stem increment cores from black spruce trees around the latitudinal tree line near Inuvik. This research will consist of remeasurement of permanent plots, foliage distribution and light measurement, establishment of pruning experiment and stem core sampling near Inuvik....

The Relation Between Postglacial History and the Modern Genetic and Morphologic Diversity of Jack Pine (Pinus banksiana) in Western Canada
Principal Investigator: MacDonald, Glen M
Licensed Year(s): 1989 1988
Summary: Dr. Glen MacDonald and his team will be obtaining lake sediment cores, samples of pine needles, cones, seeds and tree-ring cores from 2 sites near Hay River. Fossil pollen from the sediment will be used to document the chronology of pine migration into the NWT following the last ice-age. The study will be used to understand postglacial history of northern plants....

The postglacial history of the northern treeline in the Kazan River region
Principal Investigator: MacDonald, Glen M
Licensed Year(s): 1988
Summary: to obtain lake sediment cores, peat samples, and tree-ring cores in the Kazan river region to examine the postglacial history of the northern treeline in this region...

Licence #4102
Principal Investigator: Jacoby, Jr., Gordon C.
Licensed Year(s): 1984
Summary: To collect core samples from trees for later annual ring studies that will provide information on the climate during the history of the tree....

Licence #2205
Principal Investigator: Elliott, Deborah
Licensed Year(s): 1977
Summary: Ph.D. program: to ascertain the stability of northern treeline....
