1. Hierarchy of stress tolerance for flowering plants in extreme polar desert. 2. Initial phase of primary succession following glacial retreat. 3. Life of plants in extreme environments. 4. Baker Lake experiment.
Principal Investigator: Svoboda, Josef
Licensed Year(s): 1994 1993 1992 1991 1988 1987
Summary: The aim of projects 1 and 2 is to learn how plants returned to the arctic following the retreat of the ice sheet that covered Ellesmere Island some 8000 years ago. This research will also help to determine what effect climate warming will have for the plant communities of the high arctic. Project 3 will involve the filming of plant life in the high arctic. Project 4 is part of an on-going study...


Palynological studies in the Mackenzie Observatory
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....


Long-term Stability of Arctic Island "Oases"
Principal Investigator: Gajewski, Konrad
Licensed Year(s): 2008 2004 2001 1994 1993 1992 1991 1990
Summary: This study will investigate the long-term stability of the arctic "oases" of Polar Bear Pass and Hot Weather Creek by the pollen analyses of lake sediment cores. The sediment that accumulates in the bottom of lakes provides a history of the conditions in the lake. The pollen incorporated in the sediment can be interpreted to give an idea of the climate and vegetation for the past several thousand ...


Field Sampling and Collecting of Tertiary Sediments in the Geodetic Hills Fossil Forest Locality, Eastern Axel Heiberg Island, NWT, for Plant Macro-Fossils
Principal Investigator: Gruchy, C.G.
Licensed Year(s): 1990 1989 1988 1987
Summary: The Researcher and team will study the Geodetic Hills Locality. They will collect plant macrofossils to identify and classify the fossil pollen and to determine botanical affinities, deduce and describe the paleoecology and the paleoenvironment....


Mesoscale climates and paleoclimates in Baffin Island
Principal Investigator: Jacobs, John D.
Licensed Year(s): 1994 1993 1992 1991 1990 1988 1987
Summary: Dr. Jacobs is returning with his students to continue his investigation of changes in climate and environment over the last 8000 years....
