Année(s) de permis: 2013 1998 1996 1990
Résumé: The objectives of the research are 1) to collect remains of Silurian and Devonian fishes, and 2) to collect remains of Silurian trilobites. Activities are limited to travel, residence at camp locations and collection of fossils. Helicopters will be used to access camp sites. We plan to land at Avalanche Lake on July 15, spending 6 days collecting fossils at Avalanche Lake, followed by one day of t...


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.
chercheur principal: Svoboda, Josef
Année(s) de permis: 1994 1993 1992 1991 1988 1987
Résumé: 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...


Cambrian sedimentology and paleontology
chercheur principal: Pratt, Brian R.
Année(s) de permis: 1995 1993
Résumé: The Cambrian period is an interval of geologic time that is poorly known in arctic Canada. Previous studies have been very basic and almost no fossils have been recovered. Sections of sedimentary rock will be measured in detail, with attention focused on the structure of the sediments as well as the presence of fossils. A map will then be constructed showing the layers in which fossils occur. ...
