Summary: The objectives of the field program are to quantify egg deposition by depth on available habitat for fourteen known or suspected representative shallow reefs and for ten representative deep water reefs in Nonacho Lake, also to conduct mercury sampling in Lake Trout from this lake. At each of the known or suspected lake trout spawning reefs, a total of 10 numbered egg nets will be buried in cobb...

Summary: For several years, studies have been conducted to find out if contaminant levels are changing in lake trout and burbot in Great Slave Lake. The researchers have been seeing some changes with mercury levels increasing and HCH levels declining in these fish. However, there have been other changes in the fish, especially lake trout which appear to contain less fat and to be feeding closer to shore th...

Summary: The objective of this research is to investigate metals levels, particularly lead and zinc, and hydrocarbons in soils near the old CN rail bed to Pine Point mine, and Highway 5 to the Tamerlane R-190 advanced exploration site. Specific objectives are to 1) Determine levels of metals, particularly lead and zinc, and hydrocarbons on and adjacent to the old CN railbed; 2) Establish levels of metals, ...

Summary: The overall objective of the Phase I ESA is to identify and document any actual or potential environmental risks associated with the subject properties and provide recommendations for further assessment and/or risk management. The two main goals needed to meet the objective are: 1) Produce a Records Review Report of existing site information; components of the records review will be to identify ...

Summary: The objective of this study is to conduct a site investigation of the Outpost Island Mine, to further determine current environmental and physical conditions. This will include the identification and quantification of environmental impacts in soil, sediment, surface water and groundwater, and the identification of any hazardous or non-hazardous materials left on site. The research team will b...

Summary: The objectives of this project are to determine the levels of lead (Pb), zinc (Zn), iron (Fe) and copper (Cu) in edible plants in the area between Pine Point, a site of a closed Pb/Zn mine, and Fort Resolution; to determine the levels of lead (Pb), zinc (Zn) and iron (Fe) and copper (Cu) in edible plants along the railroad track between Pine Point and Hay River; to use data collected on an interce...

Summary: The monitoring objectives of this project are: to conduct a targeted scientific program to analyze heavy metals and trace elements and stable isotopes in vegetation (caribou food); to correlate the results in vegetation with concentrations in caribou from a related NCP program [Gamberg 2006]; to test if contaminant patterns in caribou tissues will vary with patterns observed in lichen/moss, or wil...

Licensed Year(s): 2006
Summary: Sampling of water, sediment, benthic invertebrates, fish inventories, and fish habitat mapping will be done. Water will be collected for chemical analysis, and limnology measurements taken. Sediment will be collected for chemical analysis and particle size analysis. Benthic invertebrates will be collected for taxonomic identification. Fish species, presence and relative abundance will be determine...

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: Currently, there is no information about the bioavailability and toxicity of metals in the Slave River delta. The goal of this research is to examine metal cycling pathways in the delta and to assess the role of aquatic vegetation for metal accumulation...
