Palynology, stratigraphy and sedimentology of the Christopher, the Hassel Bastion Ridge Strand Fiord and the Kanguk formations on Amund Ringnes and Axel Heiberg Islands
chercheur principal: Hills, L.V.
Année(s) de permis: 1993 1992 1991
Résumé: The purpose of this research is to examine the fossil spores, pollen and dinoflagellates found in the sediments of Amund Ringnes and western Axel Heiberg Islands. Additional data will be collected on the rock formations and mineral content of the areas. This research provides information on the past life history of the region as well as information about the petroleum potential....


Climate change and postglacial paleoenvironmental history of peatlands in the Mackenzie Delta area
chercheur principal: Vardy, Sheila
Année(s) de permis: 1993 1992
Résumé: This research is part of an international project that is aimed at documenting the history of changes in the treeline during the Holocene era. While much is known about the environment and climate of this era, little is known about the development of peatlands during this time. I will collect data on peat layering, pollen and fossils in order to determine how the peatlands developed during this ...


A late Cretaceous and Paleogene arctic paleoclimate record: the sedimentary sequence at Strand Fiord, Axel Heiberg Island, NWT
chercheur principal: Tarduno, John A.
Année(s) de permis: 1993
Résumé: For much of the Earth's history, the arctic has had a mild climate, quite unlike the conditions that now exist. Evidence that supports this past climate are fossil plants and animals (including crocodiles and tortoises) found in the arctic. The Earth's magnetic field has changed over time and these changes are contained in the fossils. This research will try develop a technique to age these fos...


Holocene paleoecology of the central Canadian Arctic Islands
chercheur principal: Gajewski, Konrad
Année(s) de permis: 2008 2004 2001 1994 1993 1992 1991 1990
Résumé: This ongoing project examines how vegetation has changed in response to changes in climate. I am using the history of vegetation, as recorded by the fossilized pollen that is present in lake sediments, to determine how vegetation in the arctic has changed over thousands of years. Fossilized pollen is collected by taking core samples from lake bottoms on Prince of Wales and Bathurst Islands. Pre...


Paleolimnology and sedimentology of lakes on the unglaciated terrain of Fosheim Peninsula, Ellesmere Island
chercheur principal: Wolfe, Alexander P.
Année(s) de permis: 1992 1991 1990
Résumé: The Researcher will continue to investigate lakes on the unglaciated terrain of Fosheim Peninsula to determine the former environments of high and low arctic lakes. By analyzing the physical and chemical properties of the sediments, as well as the preserved biological remains within them, the nature and timing of rapid environmental changes at the close of the last glaciation may be explained....


Tertiary Palynostratigraphy of the Beaufort-Mackenzie Basin
chercheur principal: McIntyre, David J.
Année(s) de permis: 1992 1990
Résumé: The Researcher and his assistant will collect rock samples for study of the fossil pollen to determine age, correlation with similar material from wells and to determine past climate and environments....


Field Sampling and Collecting of Tertiary Sediments in the Geodetic Hills Fossil Forest Locality, Eastern Axel Heiberg Island, NWT, for Plant Macro-Fossils
chercheur principal: Gruchy, C.G.
Année(s) de permis: 1990 1989 1988 1987
Résumé: The Researcher and team will study the Geodetic Hills Locality. They will collect plant macrofossils to identify and classify the fossil pollen and to determine botanical affinities, deduce and describe the paleoecology and the paleoenvironment....


Treeline plant population response to postglacial climatic change in North Central Canada.
chercheur principal: MacDonald, Glen M
Année(s) de permis: 1987
Résumé: To use fossil pollen and plant macrofossils from small lakes to reconstruct the response of plant populations in the treeline zone to climatic change. Modern pollen surface samples from small lakes in the treeline zone will be collected to aoid in the interpretation of the fossil pollen samples. The study area will include the boreal forest, forest-tundra and tundra zones near Yellowknife (115 W...

Licence #2776
chercheur principal: Short, Susan K.
Année(s) de permis: 1982
Résumé: To analyze changes in the modern and fossil pollen assemblages of the Central Canadian Arctic through the collection and analysis of modern moss samples and peat and lake sections....
