Principal Investigator:Tomkins, Jessica Licenced Year(s):2006
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...
Principal Investigator:Wolfe, Brent BBW Licenced Year(s):2007200620052004
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...
Principal Investigator:Beierle, Brandon Licenced Year(s):
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...
Principal Investigator:Gajewski, Konrad Licenced Year(s):20082004
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...
Principal Investigator:Wein, Ross Licenced Year(s):
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...
Principal Investigator:Smith, Rod Licenced Year(s):
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...
Principal Investigator:Wolfe, Alexander P. Licenced Year(s):19921991
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....
Principal Investigator:Overpeck, Jonathan Licenced Year(s):19931991
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...
Principal Investigator:MacDonald, Glen M Licenced Year(s):
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....
Principal Investigator:Beaudet, Hector Licenced Year(s):1989
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....
