Organic carbon cycle in the Mackenzie delta lakes
Principal Investigator: Lattaud, Julie
Licensed Year(s): 2020
Summary: This licence has been issued for the scientific research application No.4698. The project will study the dynamics of deltaic lake ecosystems over the past century through the application of recently developed molecular (lipid biomarker) and isotopic (radiocarbon and stable isotopes) proxies to lake sedimentary records. This will unravel the impact of old carbon input into aquatic ecosystems. Ra...

Climate change impacts on lake ecosystems of the western Canadian Arctic
Principal Investigator: Korosi, Jennifer B
Licensed Year(s): 2019
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 ...

Testing for Pre-Holocene Lacustrine Sediments in the Canadian High Arctic
Principal Investigator: Smith, Rod
Licensed 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...

Palaeoenvironment of Truelove Lowland (Devon Island) as Determined from Lake Sediments
Principal Investigator: Smith, Rod
Licensed Year(s): 1988
Summary: Rod Smith and Louise Hollingsworth are part of Dr. King's research party working on the Truelove Lowland. They will be extracting columns of soil from the bottoms of the larger lakes to determine what the climate was like long ago. They will also collect soil samples from the areas surrounding the lake for comparative purposes....

Changes in sea level along the Iqaluit coastline
Principal Investigator: Andrews, John T.
Licensed Year(s): 1988 1987
Summary: Raoul Miller and Mark Adams, two students of Dr. Andrews, will be continuing his work to see how sea level, climate, and vegetation have changed over the years. As in other years, they will be taking samples from the bottom of lakes near Gold Cove and along the coastline....
