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...

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...

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...

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...

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...

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...

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...

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...
