Holocene Glacier Fluctuations in Nahanni National Park Reserve, Northwest Territories, Canada
Principal Investigator: Menounos, Brian p
Licenced Year(s): 2017 2016
Summary: The objective of the study is to date the formation of terminal moraines fronting Brintnell Glacier, and analyze the glacigenic signature within the sediments of Glacier Lake in order to develop a robust chronology of glacier change on the Brintnell-Bologna Icefield. This decade to century scale chronology will be compared to regional-to-hemispheric climate proxies to evaluate the climate sensitiv...


Using the past to inform the future: A paleoecological perspective of the impacts of drought and fire on lakes, permafrost and forests
Principal Investigator: Pisaric, Michael FJ
Licenced Year(s): 2017 2016
Summary: The objectives of this research are to examine the frequency and severity of past wildfire and drought (drought-like) conditions in the southern Northwest Territories. Specifically, the research team will examine the following questions: 1) how frequent and severe have fires been in the past; 2) are fires becoming more frequent/severe due to the impacts of climate change; 3) what impact does wildf...


Cumulative Impacts Monitoring of Aquatic Ecosystem Health of Yellowknife Bay, Great Slave Lake
Principal Investigator: Chételat, John
Licenced Year(s): 2015
Summary: The main objective of this study is to investigate the ecosystem health of Yellowknife Bay. We will address the following questions through a field study: 1) What is the quality of water and sediment in Yellowknife Bay (focusing on metals, nutrients and cyanobacteria)? 2) What are the main sources and transport pathways of metals accumulating in the food web of Yellowknife Bay? 3) How much of ...


Cumulative impacts of metal deposition in the NWT: Using lead isotopes to trace local, regional and long-range sources
Principal Investigator: Chételat, John
Licenced Year(s): 2014 2013
Summary: Yellowknife Bay on Great Slave Lake is a water body of cultural, subsistence and recreational importance for the Yellowknives Dene First Nation (YKDFN) and residents of Yellowknife. The ecosystem health of Yellowknife Bay has been impacted by historical mining releases of metals (particularly arsenic), as well as long-range atmospheric transport of metals such as mercury from far-away human emissi...


Using Tree Rings and Lake Sediment to Reconstruct Streamflow and Climate in the Northwest Territories
Principal Investigator: Lamoureux, Scott F
Licenced Year(s): 2002
Summary: The objective of the research is to supplement and extend instrumental climatological and hydrological records in the NWT using dendrochronology (tree-ring) and varved lake sediment analysis. Transportation to the site will be by charter aircraft from Fo...


Coastal Impacts of Climate Change
Principal Investigator: Solomon, Steve
Licenced Year(s): 2000 1999 1997 1996 1995 1994 1993 1992
Summary: The primary objectives of the project are to map the coastline of the Canadian Beaufort Sea in terms of its sensitivity to coastal erosion and monitor changes in the coastline, and to collect information on the morphology of the coast and the sediments which compose it for use in developing and calibrating predictive models of coastal change. In order to achieve these objectives previously proven ...
