This licence is being issued for the scientific research application no. 983.
The objective of this study to examine lakes possibly affected by the proposed Mackenzie Gas Project pipeline, and lakes that can serve as future control/reference sites. The researchers will measure the following: nutrients and metals in lake water and sediments, lake water quality (DO, pH, conductivity, etc.), and ...

Summary:
The research will examine streams possibly affected by the proposed Mackenzie Gas Project pipeline, and streams that can serve as future control/reference sites. Measurements of stream nutrients, metals in stream water, water quality (DO, pH, conductivity, etc.), stream characteristics (flow, width, depth, etc.) and aquatic invertebrate abundance/species composition will be completed. Possible t...

2006 Summary:
This study is designed to determine what the levels of contaminants are in char when these fish return from feeding in the ocean in the summer.
This is the fourth year of a study investigating the contaminant levels in sea-run Arctic char as they return from feeding in the ocean. The reason this study is being conducted is to provide communities with more information on the chemical levels in t...

Summary:
This study is designed to investigate various measures of small fish health at a number of locations along the Mackenzie River. The researchers want to find out if small fish health is different near oil seepages and the islands at Norman Wells than in other parts of the river. Also, the researchers will investigate fish and benthic invertebrate abundance and species composition at selected strea...

Summary:
This study is looking at the contaminant levels in lake trout and burbot in Great Slave Lake and in arctic char after their return from feeding in the ocean. Twenty burbot and twenty lake trout will be collected from the West Basin of Great Slave Lake by...

Summary:
It has recently been learned that predatory fish in some lakes in the Mackenzie Basin have very high concentrations of mercury. This study will try to determine why the mercury concentrations are high. The researcher will fly into Cli Lake. A boat, a depth sounder and a global positional finder will be used to find out how deep the lakes in different spots. The temperature of the water, its acidit...

Summary:
Researchers will collect samples of sediments from the bottom of Great Slave Lake at sites near Hay River, the Slave River delta and the channel region east of the Slave River. This data will allow a better understanding of how fast sediments are deposited on the lake bottom in various regions. Researchers will also collect small animals (invertebrates) which are eaten by fish as part of an over...

Summary:
The Researchers will collect a series of sediment and water samples. These will be analyzed for plant nutrients, concentration of microscopic plant cells, bacteria, suspended solids, dissolved oxygen and organic contaminants. Microscopic animals will also be netted. They will determine the abundance and composition of the animals and conduct experiments to measure their feeding rates and fat cont...
