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...

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 ...

Summary: In the summer of 2005, the researchers wish to visit two locations on Prince Patrick Island to examine some unusual rock formations referred to as cold-water seep mounds in order to better understand how they were formed. The work will consist of a 2-pe...

Summary: Early Eocene (~55 million year-old) rocks of the Eureka Sound Group preserve a time when the Canadian High Arctic had a warm, temperate climate, and was home to reptiles and a diverse mammalian fauna. To date, the Eureka Sound fossil vertebrate fauna ha...

Summary: The purpose of this project is to recover remains of ice-age mammals from Banks and Melville Islands, in order to determine when and for how long animals such as woolly mammoths managed to live in this part of the Arctic. There is suggestive but meager e...

Summary: This research is a study of the changes in the climate and vegetation across the Canadian Arctic for the past 10 000 years. By studying lake sediments, the researchers will determine how climate changes in the past affected the vegetation of the region....

Principal Investigator: D'Arrigo, Rosanne
Licensed Year(s): 2004
Summary: The overall goal of the project is to develop tree-ring records from old growth trees at northern treeline locations in Canada and Alaska. This information is used to reconstruct Arctic and Northern Hemisphere temperatures over the past several centuries...

Licensed Year(s): 2003
Summary: The goal of this project is to collect a sample of the Acasta Gneiss from the Slave Craton to be used to represent the peoples and indigenous communities of Canada on the grounds of the Smithsonian Institution's National Museum of the American Indian in...
