International Cryosol Tour
Principal Investigator: Tarnocai, C.
Licenced Year(s): 1991
Summary: This tour and the associated meetings will focus on the genesis, classification and management of permafrost soils (Cryosols) and the possible effect of climate change on these soils....


Fossil and Modern Coleopteran Ecology in Arctic Canada
Principal Investigator: Morgan, Alan
Licenced Year(s): 1991
Summary: The Researchers will collect sediment samples. Insect fossils will be extracted and analysed. The insect communities recovered will provide an indication of the climatic conditions in the area at the time the sediments were deposited. The age of the sediments will be determined with radiocarbon or other dating methods....


Geology of Cretaceous and Tertiary Strata, Bylot Island, Northwest Territories
Principal Investigator: Burden, Elliott
Licenced Year(s): 1991 1990 1988 1987
Summary: The Researcher and associate will collect samples of shale and sandstone from cliffs. They will be taken to Memorial University to be analysed for their remnant magnetization. This research applies in regional correlation studies of marine and terrestrial strata and in site specific studies of the geologic development of this part of the Arctic....


Hierachy of Stress Tolerance for Flowering Plants in Extreme Polar Desert and Secondary Metobolites in Prostrate Willows in Sverdrup Pass, Ellesmere Island
Principal Investigator: Svoboda, Josef
Licenced Year(s): 1994 1993 1992 1991 1988 1987
Summary: The Researcher will continue an ongoing program in Sverdrup Pass: Ecology of polar oases. The study will assist in understanding the origin, development, maintenance and future of these isolated ecosystems in the midst of a polar desert....


Trophic Relationships and Energetics of Arctic Cod in High-Arctic Marine Food Chains
Principal Investigator: Hop, Haakon
Licenced Year(s): 1991 1990 1988
Summary: The Researcher and his assistant will collect Arctic cod. Samples of these will be taken and studied to investigate the feeding ecology of Arctic cod and the energy flow through Arctic cod from zooplankon to marine mammals and sea birds....


Devonian Carbonates and Reef Development
Principal Investigator: Pedder, Alan E.H.
Licenced Year(s): 1990
Summary: The Researcher will collect 1/2 to 2 kilogram samples of limestone. These are sent to a lab for processing which leaves small fossils of calcium phosphate. These are studied to determine their age and the conditions of the life of the fossils....


Enivronmental Studies of the Ice-Bearing Region in Canadian Arctic
Principal Investigator: Fujino, Kazuo
Licenced Year(s): 1990
Summary: The Researcher and field team will conduct a geological survey and topographic traverse survey around the massive ground ice. They will take samples for ecological study and geochemical analysis....


Productivity of Marine Mammal Food Chains in the Northwest Passage
Principal Investigator: Welch, Harold
Licenced Year(s): 1993 1992 1991 1990 1988 1987
Summary: Dr. Welch and his project personnel will continue work on a study which began in 1984. The objective of the study continues to be the quantification of food web leading to marine mammal and bird production in the Canadian Marine Arctic....


Genetic Variation and Population Structure in Boreal and Subarctic Mire Sedges (Carex, Cyperaceae)
Principal Investigator: Waterway, Marcia J.
Licenced Year(s): 1990
Summary: The Researcher and her team will sample approximately twenty different species of sedges in a range of wetlands between Edmonton and Yellowknife. They will find out the range of conditions in which each species grows best and will determine whether broad tolerance results from inherited variability or from the ability of individuals of each species to tolerate different conditions....


Bluenose Lake Natural Resources Survey
Principal Investigator: Scotter, George
Licenced Year(s): 1990
Summary: The Researcher and team will carry out this survey at the request of the community of Paulatuk. They will summarize the existing knowledge of the natural resources of the Bluenose Lake Region. A total of about 20 stops will be made to examine the vegetation, soil, wildlife and physiogeography and to collect plant and soil samples....
