Landscape Response from Altering Ice-Rich Terrain
Principal Investigator: Lamoureux, Scott F
Licensed Year(s): 2018
Summary: The goal of this study is to understand landscape response following ice-rich terrain alteration. The research team will install temperature loggers in 2" PVC pipe from the surface down to 3 m depth to monitor the ground temperature evolution over the summer season in the pits. The team will also use the geophysical technique electrical resistivity tomography (ERT) to measure the amount and st...


Watershed delineation of permafrost disturbance on eastern Banks Island, NWT: a geomatic approach for predicting water quality impacts
Principal Investigator: Lamoureux, Scott F
Licensed Year(s): 2015
Summary: The objective of this work is to investigate the impact of permafrost disturbance on water quality by examining varying sizes of watersheds with different magnitudes of disturbance. The impact of disturbance on water quality will be examined in a number of different research questions: 1) does watershed size impact downstream water quality where there is the same magnitude of disturbance; 2) is wa...


Long term river flow and climate conditions reconstructed from lake sediments
Principal Investigator: Lamoureux, Scott F
Licensed Year(s): 2012
Summary: The research team seeks to obtain sediment cores from two lakes in order to reconstruct past river flow in the region. This work, which builds on similar efforts at "Shellabear" lake, NWT, and work at Cape Bounty (Nunavut), will focus on long term river flow characteristics and the climate factors that control them. The fieldwork involves augering a hole in the lake ice and lowering a tube int...


Evolution of coastal lakes in the High Arctic
Principal Investigator: Lamoureux, Scott F
Licensed Year(s): 2010 2009
Summary: The goal is to distinguish the chemical and physical processes acting on different coastal lakes in order to understand how the systems have developed through time. Water from lakes at both field sites will be sampled for laboratory analysis. This is the fourth year of sampling at Shellabear Lake, and we are testing to see if the lake at Chevalier Bay is also hypersaline. We will take a short...


Climate change reconstructed from lake sediments
Principal Investigator: Lamoureux, Scott F
Licensed Year(s): 2007
Summary: The goal of this project is to collect sediment cores and water samples from a lake, to be analysed as an indication of past snow melt and stream flow in the area. Two personnel will camp at the site for 5 days in late May. In late June, early July and/or late August they will return by helicopter from a neighboring camp in Nunavut for two or three visits, 3-4 hours each visit. A skidoo will be...


Using Tree Rings and Lake Sediment to Reconstruct Streamflow and Climate in the Northwest Territories
Principal Investigator: Lamoureux, Scott F
Licensed 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...


Late Quaternary History of the Richardson Mountains and the Melville Hills
Principal Investigator: Lamoureux, Scott F
Licensed Year(s): 2001
Summary: The research will require fieldwork in the Richardson Mountains between 27 April and 8 May, 2001. Research will involve the development of a high-resolution paleoenvironmental record based on lake sediments from up to six lakes in the Richardson Mountains and the Melville Hills in the NWT. Transportation in the field for the Dempster Highway study will be by snowmobile and snowshoes. If snow cov...
