Summary: 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...

Principal Investigator: Jette, Helene
Licensed Year(s): 1995 1993 1992
Summary: This project continues to examine the history of plant communities in the Mackenzie River and Delta regions over the past 15,000 years. Using a hand auger, core samples of sediments are taken from lake bottoms and the sediments are analyzed for the presence of pollen and diatoms. Radiocarbon dating, a technique used to estimate age, will estimate when certain species were present in the past....

Licensed Year(s): 1994 1993 1992 1991 1990 1989 1988 1987
Summary: Begun in 1985, this project will continue the study of plant evolution in high latitudes and the exploration for fossils in rocks of the Eureka Sound Group of Axel Heiberg and Ellesmere Islands. This season the field work will expand to Strathcona Fiord area and to east central Axel Heiberg Island. This information is used in the interpretation of global climatic change and the evolution of temper...

Principal Investigator: Smith, Derald
Licensed Year(s): 1988
Summary: Dr. Smith and his two students are trying to find out the extent of a glacial lake that once stretched from the Redstone River to Fort Good Hope. They are collecting samples of ancient, buried plant material from river cutbanks to see how old these deposits are and to determine what kinds of plants once grew along the western shores of the lake long ago....

Principal Investigator: Ritchie, J.C.
Licensed Year(s): 1988 1987
Summary: The sampling of lake sediment for subsequent laboratory analysis of pollen and other contained material, with the final aim to reconstruct postglacial vegetation and climate....

Principal Investigator: Gruchy, C.G.
Licensed 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....

Principal Investigator: Ritchie, J.C.
Licensed Year(s): 1979
Summary: To examine and sample unconsolidated sediments of small unnamed lake for future laboratory analysis and dating. The ultimate objective is to reconstruct the past vegetation and climate of the area....

Principal Investigator: Ritchie, J.C.
Licensed Year(s): 1978
Summary: To examine and sample the unconsolidated sediments of various small lakes in an area surrounding Hyndman Lake (50 km. radius) ESE of Inuvik, for the purpose of making laboratory analyses of Carbon - 14 age, pollen stratigraphy and other microfossils. The ultimate objective is to reconstruct the past vegetation and environment of the area....
