Forest Research in the Mackenzie River Delta
Principal Investigator: Johnson, Art
Licenced Year(s): 2005
Summary: Researchers are currently working on a project at Banks Island where they will measure stumps and logs of 3-million-year-old trees and attempt to understand the species that grew there, how tall the trees were, their diameters and the annual production of wood and foliage. Researchers know the Banks Island trees were spruce, larch and pine. To accurately determine what the ancient trees looked l...


Past climates of ancient forests on Banks Island
Principal Investigator: Williams, Christopher J
Licenced Year(s): 2005 2003
Summary: The objective of this project is to make detailed measurements of fossil plants that grew at high latitudes between 12 and 2 million years ago. The researchers will use these and previously obtained data to test the hypothesis that until about 28 million years ago arctic wetland forests were high biomass forests dominated by deciduous conifers, but by 12 million years aga, these were replaced by ...


Ecophysiological Reconstruction of High Latitude Fossils
Principal Investigator: Jagels, Richard
Licenced Year(s): 2000
Summary: The NWT component of this study is to examine how the anatomical features of wood from the genus Larix, vary with changes in latitude. This will be compared to work done on Axel Heiberg Island, Nunavut where a fossil forest of mummified wood approximately 45 million years old was found. Certain features of wood can provide clues to assess winter temperatures but these features vary with latitude....


Evolution of high latitude floras
Principal Investigator: Basinger, James F.
Licenced Year(s): 1994 1993 1992 1991 1990 1989 1988 1987
Summary: The researchers will continue to examine the fossil plants that are contained in sediments that are 40-70 million years old. Sites include the northeastern region of Axel Heiberg Island and the Stenkul Fiord region of central Ellesmere Island. A trip to Bathurst Island is scheduled to verify a more recent discovery of fossilized plants. The data collected wil contribute to our knowledge about t...


Studies on the Arctic Fossil Forests
Principal Investigator: Gruchy, C.G.
Licenced Year(s): 1990 1989 1988 1987
Summary: To determine the nature and extent of several Arctic fossil forests; map stumps and logs. To remove some mummified wood for conservation research at CCI. To search for forest areas. Reconnaissance of other possible fossil forest areas and of reported Mesozoic fish locality....
