Summary:
The objectives of this research is to:
1) determine if thaw slumping results in the loss of a large-bodied zooplankton species (Daphnia) from lakes; and
2) measure polychlorinated biphenyl concentrations in lake sediments near the Distant Early Warning Line site in Tuktoyaktuk, to assess whether legacy contamination is still evident.
The research team will be collecting sediment cores from ...

The purpose of the study is to continue investigating whether contaminant levels are changing in fish in the Northwest Territories with a focus on Great Slave Lake which the research team has been studying since the early 1990s. The plan is to collect lake trout from Great Slave Lake (Hay River area and Lutsel K’e area). The research team also plans to collect burbot from the Lutsel K’e and Fort R...

Summary:
This is a study investigating the contaminant levels in sea-run Arctic char as they return from feeding in the ocean. The aim of this study is to provide communities with more information on the chemical levels in these fish. By making these chemical measurements in char and comparing them with chemical levels in marine mammals, there would be a possibility to demonstrate that char is a good food ...

Summary:
This project aims to obtain a better understanding of the sensitivity of slopes to disturbance from development, especially in the context of progressive climate warming. It will also identify baseline levels for natural and anthropogenic contaminants,...

This study is based on earlier research conducted by the Department of Fisheries and Oceans which found that fish in many lakes in the Mackenzie River Basin had high mercury concentrations. This study examines the environment in which the fish live in o...

1994 Summary:
The researchers will collect samples of sediments from the bottom of Great Slave Lake at sites near Fort Resolution and Lutsel K'e. This data will allow a better understanding of how fast sediments are deposited on the lake bottom in various regions. Researchers will also collect invertebrates and fish samples as part of an overall study of contaminants in the lake's ecosystem....

Summary:
The project is to see how different organic contaminants change with different preparation methods of the important fatty foods used by the Inuit. The research will focus on food prepared for eating. Samples (aprox. 120) will be collected and prepared by a research assistant from the community. The study aims to find the best ways to prepare these food items to reduce exposure to these contamin...

Summary:
Amituk Lake and the east coast of Cornwallis Island is a research site for documenting the occurence and movement of organic and inorganic contminants from winter snowpack into a freshwater lake. Numerous tests for snowpack water content and chemistry are carried out before snowmelt begins. Chemical and flow measurements are also taken at 6 streams and the lake outlet....

1993 Summary:
There is only limited information on contaminant trends in arctic ecosystems. This long-term study is examining the amounts of contaminants present in arctic ice caps. By taking core samples from ice caps, the researchers are able to measure the levels of contaminants that have been deposited by precipitation over many years. This study will also improve our understanding of the levels of conta...
