Canadian Arctic Archipelago Paleoenvironments: Beaufort Sea Bowhead Whale History Component
Principal Investigator: Dyke, Arthur
Licenced Year(s): 1998
Summary: The objective of the work in western Victoria Island is to start establishing a postglacial history for the Beaufort Sea bowhead whale. We have done this very successfully for the Baffin Bay bowhead whale. This is a study of geological fossils, not of living whales, nor of bones at archaeological sites. This information will be used to find out how much sea ice cover has changed through time. A 2 ...


Multi-year study of high arctic periglacial processes and related quaternary history
Principal Investigator: Washburn, A.L.
Licenced Year(s): 1994 1993 1992 1991 1990 1988 1987
Summary: The researcher will continue the long-term investigation of how the landscape has changed since the glaciers left 10 000 years ago. In particular, this study is examining the effects of frost and permafrost on the landscape. The researcher will be returning to several sites visited in previous years in order to check earlier observations....


Expedition Fiord: Sedimentary Environment Since the Ice Ages.
Principal Investigator: Gilbert, Robert
Licenced Year(s): 1993 1992 1991 1990 1988
Summary: The researcher wishes to recover cores of sediment about 2 meters long from the sea floor near Expedition Fiord. These cores will provide confirmation of past acoustic surveys and direct evidence of changes in the physical and biological environment of the fiord. Seven sites in the fiord will have sediment cores removed....


Quaternary Geology of Hudson Strait
Principal Investigator: MacLean, Brian
Licenced Year(s): 1993 1990
Summary: The Researcher and his team will be travelling through Hudson Strait by research ship to take samples of the deposits and sediments in the Strait. They will be investigating the history and conditions of the area based on the sediments record in order to detail the late glacial and post glacial conditions of the Strait....


Quaternary Geology of Northwest Baffin Island
Principal Investigator: Dyke, Arthur
Licenced Year(s): 1990
Summary: The Researcher and his team will make maps of land features and material that rests on rocks....


Quaternary Geology and Geomorphology, Southern Melville Peninsula, NWT
Principal Investigator: Dredge, Linda
Licenced Year(s): 1990
Summary: The Researcher and her assistant will map the terrain and take soil and rock samples for laboratory studies....


Reconstruction of post-glacial vegetation and climate in the Inuvik and Tuktoyaktuk area
Principal Investigator: Ritchie, J.C.
Licenced Year(s): 1988 1987
Summary: Dr. Ritchie is looking at live plants and the remains of plants at the bottom of lakes to see how plants and weather have changed since the glaciers left the Inuvik and Tuktoyaktuk area 10,000 years ago....


The postglacial history of the northern treeline in the Kazan River region
Principal Investigator: MacDonald, Glen M
Licenced Year(s): 1988
Summary: to obtain lake sediment cores, peat samples, and tree-ring cores in the Kazan river region to examine the postglacial history of the northern treeline in this region...


The relationship between postglacial history and the modern genetic and morphologic diversity of jackpine (Pinus banksiana) in the Mackenzie River valley
Principal Investigator: MacDonald, Glen M
Licenced Year(s): 1989 1988
Summary: to obtain lake sediment cores, samples of pine needles, cones and seeds, and tree-ring cores from 10 sites along the Mackenzie River between Norman Wells and Fort Simpson in order to document the chronology of pine migration into the Mackenzie Valley following the last ice-age and to test hypotheses regarding postglacial history of northern plants and distributions of genetic diversity...


Licence #7118
Principal Investigator: Green, John M.
Licenced Year(s): 1987
Summary: To continue the ongoing study designed to investigate the postglacial dispersal patterns of freshwater and anadromous fishes by determining genetic relationships between fish populations inhabiting the rivers. Tissue samples will be collected and the genetic variations will be determined through analysis for selected proteins....
