Principal Investigator: Baltzer, Jennifer L
Licensed Year(s): 2023
Summary: This licence has been issued for the scientific research application No.5567. This project has two primary objectives: 1) To investigate the differences in shrub productivity traits between undisturbed and disturbed tundra sites to better understand the impact of shrub expansion and disturbance on ecosystem function. 2) To investigate the impact of shrub productivity trait differences on deco...

Summary: The goal of this research is to understand how landscape processes influence the quantity and quality of soil carbon in the Mackenzie Delta Region. Particular attention will be paid to the depth distribution of soil carbon and how it is affected by differences in vegetation and soil forming processes. Key environmental differences that will be examined include forest vs. tundra and delta vs. uplan...

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 reflec...

Summary: Since the 1970s, the oil and gas industry has drilled at least nineteen exploratory wells in the Kendall Island Bird Sanctuary. Observations at associated drilling mud-sumps have been made; however, there remains a paucity of field data describing site conditions. It is also appreciated that construction of the proposed Mackenzie Valley pipeline will stimulate the development of Niglintgak and Tag...

Principal Investigator: Callow, Lin
Licensed Year(s): 2004
Summary: The objective of these trials is to evaluate the performance of Low Ground Pressure Vehicles (LGPV) on frozen tundra without surface preparation. The effects of LGPV passage on soil, permafrost, and vegetation will be monitored and the details of each tr...

Principal Investigator: Hutchinson, Tom
Licensed Year(s): 1999
Summary: The purpose of this study is to re-measure the occurrences of vegetation, identifying all the different species and measuring them quantitatively in places that were measured 13 years ago. The focus this time will be on the ability of the tundra ecosystem to recover when a strong chemical stress ceases. The team will be flown in early August from Inuvik to the old DEW Line landing strip at Mallo...

Principal Investigator: Karlqvist, Anders
Licensed Year(s): 1999
Summary: The overall goal of the expedition Tundra Northwest 1999 is to study geographic variation of terrestrial and freshwater ecosystems of the tundra. By using the CCG icebreaker Louis St. Laurent for transport and as a scientific platform the the expedition route will include a longitudinal gradient from Baffin Island to the northern coast of Alaska and a latitudinal gradient through the Canadian Arc...

Principal Investigator: Henry, Gregory
Licensed Year(s): 1995 1994 1993 1991
Summary: Using the latitudinal treeline, the Researchers will examine plant communities in forest, treeline and tundra communities. They will determine locations for permanent plots to monitor long-term changes in vegetation as a response to predicted global warming....
