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...

This is the continuation of a multi-year project to determine the long-term (1000's of years) vegetation history. Researchers will collect sediment samples from the bottom of a series of small lakes. Samples of the upermost sediment will be collected with a dredge or short corer. In the lab pollen will be extracted and identified. This data will be entered on a databank to be used to determine th...
Principal Investigator:Hills, L.V. Licenced Year(s):
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....
Principal Investigator:Vardy, Sheila Licenced Year(s):
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 ...
Principal Investigator:Tarduno, John A. Licenced Year(s):
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...

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:Gould, William Licenced Year(s):19941993
The research involves the collection of lichens and spruce tree seed and pollen for analysis. The researchers will analyze the lichen samples for pollutants and will study the seed and pollen collections as part of a climate change study....
Principal Investigator:Wolfe, Alexander P. Licenced Year(s):
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....
Principal Investigator:Bouchard, Michel A. Licenced Year(s):
The Researchers will study the ejecta which is material formed as a result of the explosive impacting and throw out of rocks at the moment of meteorite impact. They will also investigate the pollen content of the glacial sediments trapped within the crater rim....
Principal Investigator:McIntyre, David J. Licenced Year(s):1992
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....
