While water and sediment quality monitoring in areas of industrial developments is an integral part of water management programs to ensure protection of ecosystems, absence of long-term measurements can make it challenging to define reference conditions effectively. As a contribution to the Marian Watershed Stewardship Program (MWSP), this research uses paleolimnological approaches to establish ba...

The objectives are to draw together multiple sources of information so that we may (1) examine change in lake area in this ecoregion, (2) assess amount of meadow habitat lost to rising water levels in core bison range, (3) investigate whether recent changes are part of a longer-term cycle and evaluate the causes of this change, (4) determine a way to document and integrate local and traditional kn...
Principal Investigator:Laidlaw, Shawn Licenced Year(s):
The purpose of this project is to:
1) coordinate monitoring and research efforts in the watershed between the community, government, and universities;
2) understand current aquatic health of the watershed using water quality, macroinvertebrates, aquatic furbearers and fish as indicators of ecosystem health;
3) understand historical environmental change and contaminant loading in the watershed u...

The objective of this research is to study the impacts of climate change on boreal and aquatic ecosystems in the Mackenzie Delta region. By doing so, the researchers hope to gain a better understanding of the effects of long-term climate change on these ecosystems. Their study will utilize dendrochronological and paleolimnological methods to examine spruce forests and lake sites situated in the in...

Melting permafrost can alter soils and surface runoff. The effects of such changes have been modeled but never evaluated experimentally. Arctic lake productivity is not well articulated and sensitivities to disturbance (e.g., climate change, water withdrawal for development use) remain unpredictable. The objective of this study is to develop a hydrologic model for melting permafrost conditions, as...

This ongoing research project will formulate a history of the frequency and magnitude of floods, droughts, and corresponding ecological responses in the Mackenzie Basin Deltas over the past 1000 years. Fieldwork in 2004 will focus on continued sampling a...

The Researcher will continue to investigate lakes on the unglaciated terrain of Fosheim Peninsula to determine the former environments of high and low arctic lakes. By analyzing the physical and chemical properties of the sediments, as well as the preserved biological remains within them, the nature and timing of rapid environmental changes at the close of the last glaciation may be explained....
