Summary: This study examines (1) the regeneration dynamics of White spruce in the Mackenzie Delta and Black spruce on seismic lines; (2) the potential for seeds to disperse on snow; (3) pollen dispersal; and (4) pollen production. Study sites in the Mackenzie D...

Summary: 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 ...

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....

Principal Investigator: McIntyre, David J.
Licensed Year(s): 1992 1990
Summary: 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....

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: Short, Susan K.
Licensed Year(s): 1982
Summary: 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....

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....
