Climate forcing factors and the record of climatic variability in the western Canadian Arctic during the past 2000 years
Principal Investigator: Tomkins, Jessica
Licenced Year(s): 2006 2005
Summary: The idea of the study is that researchers use the layers of sediment in a lake-bottom to figure out what the climate was like every year from last year to 2000 years ago. The researchers want to 1) look at cores of lake-bottom sediment that show layers...


Paleohydrological and Paleoecological Reconstruction of the Mackenzie Basin Deltas
Principal Investigator: Wolfe, Brent BBW
Licenced Year(s): 2007 2006 2005 2004 2003 2002
Summary: This project will formulate a history of the frequency and magnitude of floods and droughts and corresponding ecological responses in the Mackenzie Basin deltas over the past 1000 years. Fieldwork in 2003 will focus on assessing seasonal variability of l...


Late Quaternary hydrological and climatic history of the lower MacKenzie River basin
Principal Investigator: Beierle, Brandon
Licenced Year(s): 2002
Summary: The research team will obtain sediment cores from a series of lakes near Reindeer Station and Inuvik for the purpose of reconstructing the hydrological, climatological and geomorphic history of the lower Mackenzie River basin. The research will require fieldwork between 15 April and 25 April. Research will involve the development of a high-resolution paleoenvironmental record based on lake sedime...


Environmental History of the Central Canadian Arctic.
Principal Investigator: Gajewski, Konrad
Licenced Year(s): 2008 2004 2001 1994 1993 1992 1991 1990
Summary: The research team will be transported to the base camp site by PCSP Twin Otter, where a small camp will be set up. The camp will consist of one sleeping tent per team member and one cooking tent. All non-burnable garbage will be packed out, and human waste buried at the camp sites. The research team plans to access 6-8 lakes within walking distance of the base camp. Lake sediment cores will be col...


Fire regimes in the western boreal forest and post-fire dynamics of the forest: implications for forest fire management and climate change.
Principal Investigator: Wein, Ross
Licenced Year(s): 1995
Summary: The researchers will sample 200-300 forest stands in Wood Buffalo National Park and surrounding areas as well as in the Fort Simpson area. A number of measurements will be taken in each site as well as soil cores and sections of decomposing logs and snages. These will be taken to the U. of A. for analysis. In addition, sediment cores will be taken in lake sediment and/or peatlands for stratigra...


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...


A Paleolimnological Approach to Environmental Reconstruction on the Pre-Foxe Terrain, Cumberland Peninsula, Baffin Island
Principal Investigator: Wolfe, Alexander P.
Licenced Year(s): 1992 1991 1990
Summary: The bathymetry of 3 lakes will be determined with a portable echo sounding device. The deepest part of each lake will be cored. Ice thickness and water quality will be monitored. Samples of modern sediments will be taken for comparisons with fossil material preserved in the cores....


High-resolution paleoclimatic time series from annually-laminated lake sediments: Baffin Island and Northern Labrador
Principal Investigator: Overpeck, Jonathan
Licenced Year(s): 1993 1991 1989
Summary: Mr. J. Overpeck and his team will collect samples of mud from the bottom of Ogac Lake. In their laboratory, they will then examine the chemistry, texture, and fossils in this mud in hopes of documenting how the southern Baffin Island environment (mainly c...


The Relation Between Postglacial History and the Modern Genetic and Morphologic Diversity of Jack Pine (Pinus banksiana) in Western Canada
Principal Investigator: MacDonald, Glen M
Licenced Year(s): 1989 1988
Summary: Dr. Glen MacDonald and his team will be obtaining lake sediment cores, samples of pine needles, cones, seeds and tree-ring cores from 2 sites near Hay River. Fossil pollen from the sediment will be used to document the chronology of pine migration into the NWT following the last ice-age. The study will be used to understand postglacial history of northern plants....


Quaternary history of Lake Hazen Basin, Ellesmere Island
Principal Investigator: Beaudet, Hector
Licenced Year(s): 1989 1988 1987
Summary: Dr. Beaudet and two students are investigating where the glaciers where long ago. They will also be extracting cores of sediments to see how the climates and plants differed between then and after the glaciers melted....
