Water Ecosystem Monitoring using Earth Observations
Principal Investigator: Chamberland, Joseph
Licenced Year(s): 2016 2015
Summary: The research project Water Ecosystems Monitoring using Earth Observation aims to define an Earth Observation (EO) driven monitoring program to provide information towards monitoring environmental indicators of northern ecosystem health. Once the project is done information on water indicators including water temperature, suspended sediment concentrations, water levels, and ice quality and will be ...

Climate change reconstructed from lake sediments
Principal Investigator: Lamoureux, Scott F
Licenced Year(s): 2007
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...

Testing for Pre-Holocene Lacustrine Sediments in the Canadian High Arctic
Principal Investigator: Smith, Rod
Licenced Year(s): 1994
Summary: This study will test the hypothesis that pre-Holocene (older than 10, 000 years) lake sedimentary records exist within modern lake basins found on Ellesmere Island. Recent research has not been able to penetrate beyond a layer of course sand and pebbles. Recent technological improvements in the coring apparatus should allow the full penetration of this material, as well as the hypothesized older...

Persistent organic contaminants in the Great Slave Lake ecosystem
Principal Investigator: Evans, Marlene S.
Licenced Year(s): 1995 1994
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...

Study of Contaminants and Bio-indicators of Environmental Change in Arctic Lakes
Principal Investigator: Smol, John
Licenced Year(s): 1994 1993 1992
Summary: The Researchers will sample lakewater and lake sediments from several study sites near Resolute and in the High Arctic near Alert. At each lake they will analyze the water chemistry and collect lake muds. The lake muds contain a historical record of past pollution (black carbon particles) as well as biological indicators (for example, diatom algae) of environmental change....

Exploration Geochemistry of Gold, Slave Province, NWT
Principal Investigator: Fletcher, W.K.
Licenced Year(s): 1992
Summary: The research will involve the collection of soil, lake sediments and waters. Soil and lake sediments will be sieved to give different size fractions (sand, silt, clay, etc.) and each fraction analyzed for gold to determine which size fraction is best to use in gold exploration....

An Initial Test of Sediment Magnetic Susceptibility and its Paleolimnological Implications, Truelove Lowland, Devon Island, N.W.T.
Principal Investigator: Child, M.M.
Licenced Year(s): 1992
Summary: The Researcher will measure the magnetic susceptibility of lake sediments on Truelove Lowland....

Arctic Quaternary Geologic Field School
Principal Investigator: Retelle, Michael J.
Licenced Year(s): 1991
Summary: The field school introduces students to the processes operating in the modern physical environment in a glaciated terrain....

Holocene Paleoecology of the Central Canadian Arctic Islands
Principal Investigator: Gajewski, Konrad
Licenced Year(s): 2008 2004 2001 1994 1993 1992 1991 1990
Summary: The Researcher will collect lake sediment cores from Somerset Island and northwest Cornwallis Island. The pollen and sediment characteristics will be analyzed in a laboratory to reconstruct the vegetation and climate history of the past 8000-9000 years of these regions....

Investigation of Frost Heave in Lake Bottom Sediments
Principal Investigator: Burn, Chris R
Licenced Year(s): 1990 1987
Summary: The research team will monitor the amount of heave that occurs in lake-bottom sediments during winter, after water freezes to the bottom of lakes, because these environments are the best for examining the hydrology of frost heaving....
