Long-term aquatic ecosystem change at the southern limit of permafrost
Principal Investigator: Korosi, Jennifer B
Licensed Year(s): 2019 2018
Summary: The goal is to reconstruct long-term environmental change (hundreds to thousands of years) by examining chemical and biological fossil remains preserved in lake sediment cores, in order to better understand how thawing permafrost impacts lake ecosystems. 1) Water chemistry and plankton survey The research team will collect lake water samples from the study lakes to analyze for water chemistry...

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
Licensed Year(s): 2019 2018 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...

Hydrological and contaminant studies in the Marian Watershed, NWT, to enhance community-based cumulative effects monitoring
Principal Investigator: Wolfe, Brent BBW
Licensed Year(s): 2016
Summary: 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...

Investigating the cumulative effects of environmental change and human activity in the Tathlina watershed
Principal Investigator: Laidlaw, Shawn
Licensed Year(s): 2013 2012
Summary: 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...

A Paleolimnological Approach to Environmental Reconstruction on the Pre-Foxe Terrain, Cumberland Peninsula, Baffin Island
Principal Investigator: Wolfe, Alexander P.
Licensed Year(s): 1992 1991 1990
Summary: The bathymetry of 3 lakes will be determined with a portable echo sounding device. The deepest part of each lake will be cored. Ice thickness and water quality will be monitored. Samples of modern sediments will be taken for comparisons with fossil material preserved in the cores....
