Watershed delineation of permafrost disturbance on eastern Banks Island, NWT: a geomatic approach for predicting water quality impacts
Principal Investigator: Lamoureux, Scott F
Licenced 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...

Permafrost Disturbance Susceptibility Mapping
Principal Investigator: Lamoureux, Scott F
Licenced Year(s): 2014
Summary: The goal is to produce permafrost disturbance susceptibility maps for the region surrounding Sachs Harbour identifying areas with low, moderate and high susceptibility to future permafrost disturbance. A 25 km radius around Sachs Harbour will be systematically mapped to identify and map permafrost disturbances. GPS will be used to map the perimeter of identified permafrost disturbances. Soil s...

Long term river flow and climate conditions reconstructed from lake sediments
Principal Investigator: Lamoureux, Scott F
Licenced 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...
