Summary: The objective of this research is to determine the spatial correlation between surface properties and active-layer thickness. Six sites have been established across the treeline, between Inuvik and Swimming Point. At each site, shallow temperature cables are installed in the active-layer and near-surface permafrost and air temperatures are monitored by data logger. During this project, the res...

Summary: The Permanent Monitoring Plots will provide experimental data on forest growth and progression, cumulative impact monitoring, and will provide data for territorial and national reporting requirements. Most plots will be accessed only by helicopter. At each site, a 400 square metre plot (11.28 m radius) will be established with rebar as a centre post. All trees, shrubs and other vegetation will...

Summary: The 2005 terrestrial studies in the Inuvialuit Settlement Region (ISR) will include vegetation classification, rare plant surveys, and landform, soil and permafrost investigations. The studies will be conducted by three- or four-person crews supported by helicopter and based in Inuvik. A local assistant will be hired as part of each survey team. Air calls from a helicopter will be used to map ...

Summary: The goal of this project is to understand the complex linkages between biogeochemical cycles, vegetation, disturbance and climate across the full summer temperature gradient in the Arctic in order to better predict ecosystem responses to changing climate...

Summary: There are three main parts in the researchers' project: 1) investigating changes in vegetation cover in the Inuvik region during the past 10,000 years using fossil pollen and stomata preserved in lake sediment; 2) investigating the importance of disturb...

Summary: Since the 1970's, the oil and gas industry has drilled at least 19 exploratory wells in the Kendall Island Bird Sanctuary (KIBS), but there is a shortage of field data describing environmental conditions at the well-sites and drilling-mud sumps. In Marc...

Summary: The researchers will travel to Cape Bathurst Peninsula by charter from Inuvik and spend 2-3 days. They will collect a small number of representative specimens of Braya populations along with a general collection of associated plant species. All plant spe...

Summary: This research is a study of the changes in the climate and vegetation across the Canadian Arctic for the past 10 000 years. By studying lake sediments, the researchers will determine how climate changes in the past affected the vegetation of the region....

Principal Investigator: Siciliano, Steven D
Licensed Year(s): 2003
Summary: This study will: (1) assess sulfate-reducing bacterial diversity and mercury transformations; and (2) analyze the toxicity of contaminants deposited on vegetation and soil to wildlife that may digest it. Little is known about transformations of mercury...
