Biodiversity changes since the last Ice Age reconstructed from lake sediment cores
Principal Investigator: Herzschuh, Ulrike
Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5941. Our aim for this study would be to better understand the climate history and paleoecological since the last glacial maximum at the margin of glaciated regions and to help compare regions between formerly glaciated and unglaciated regions in terms of changes in biodiversity, the movement of the tree line and the effec...


Tracking environmental change in the Neoproterozoic Sheepbed and Keele Formations, Mackenzie Mountains, Northwest Territories, Canada
Principal Investigator: Sperling, Erik A
Licensed Year(s): 2014
Summary: The objective is to collect high quality and high resolution stratigraphic and sedimentological data of the Sheepbed and Keele Formations at their type localities, along with accompanying samples for geochemical and petrological analysis. Specifically, the overall goal is to understand how these formations at their type sections relates to their correlatives throughout northwestern Canada, and det...


The Search for Early Fossil Sharks in Lower Devonian rocks of the Mackenzie Mountains, NWT
Principal Investigator: Wilson, Mark V.H.
Licensed Year(s): 2013 1998 1996 1990
Summary: The 2 objectives of this research project are: 1) to recover some of the oldest-known body fossils of sharks and their relatives as well as other associated fossils. The anatomy of the fossil species will be described in detail and published in international journals. These fossils will allow identification of fragments of related species found at other sites worldwide, and will allow the researc...


Neo-proterozoic glacial events, Mackenzie Mountains northwestern Canada
Principal Investigator: Narbonne, Guy
Licensed Year(s): 2001 1999 1998 1996 1994 1992 1991 1989 1988
Summary: This study looks at aspects of the earth's history. The Ice Brook Formation in the Mackenzie Mountains and the Sheepbed formation are rock units that will be studied. Members of the field party will be transported to base camps by helicopter and camp moves will be done by helicopter. Ground work is to be done on foot. Data is collected through photography of rock outcrops, measurement of stratigra...


Paleoclimatic Significance of Laminated Lake Sediments from the Canadian High Arctic
Principal Investigator: Retelle, Michael J.
Licensed Year(s): 1992 1991 1990
Summary: The researchers will attempt to reconstruct climate and past environmental conditions through recovery and study of sediment cores from lakes at Taconite Inlet, northern Ellesmere Island. They will also monitor conditions under which the lake sediments are presently accumulating....


INSTAAR Geological Fieldwork 1992, Northwest Territories, Canada
Principal Investigator: Kaufman, Darrell
Licensed Year(s): 1992
Summary: Three field parties will continue investigations related to past glacial activity in the eastern arctic during the last deglaciation (12,000 - 8,000 years ago). They will also research the geologic record of environmental changes preserved in lake sediments....


Glacimarine Sedimentation in Canon Fiord, Ellesmere Island
Principal Investigator: Gilbert, Robert
Licensed Year(s): 1993 1992 1991 1990 1988
Summary: The Researcher will use a special type of echo sounder to determine the depth of the water and the thickness of the sediments beneath down to bedrock. The instrument also shows the patterms of sediment distribution around the fiord. From this, an assessment can be made of where the sediment has come from, how much there is and how the patterns of sedimentation have changed during the entire perio...


Sedimentology diagenesis and economic potential of Devonian sediments, eastern Franklinian Miogeosyncline, Bathurst Island
Principal Investigator: Brand, Uwe
Licensed Year(s): 1993 1992
Summary: The Researchers will study sedimentary rocks and fossils that were formed more than 350 million years ago in warm tropical seas. The study helps to interpret the ancient environments and will outline which rock units were most favourable to generating and hosting economic mineral deposits....


Paleolimnology and sedimentology of lakes on the unglaciated terrain of Fosheim Peninsula, Ellesmere Island
Principal Investigator: Wolfe, Alexander P.
Licensed Year(s): 1992 1991 1990
Summary: The Researcher will continue to investigate lakes on the unglaciated terrain of Fosheim Peninsula to determine the former environments of high and low arctic lakes. By analyzing the physical and chemical properties of the sediments, as well as the preserved biological remains within them, the nature and timing of rapid environmental changes at the close of the last glaciation may be explained....


An Investigation of the Chemical Paleoenvironmental Record Preserved in the Sediments of a Shallow, High Arctic Emergent Lake, Truelove Lowland, Devon Island, N.W.T.
Principal Investigator: Smith, I.R.
Licensed Year(s): 1992
Summary: Mr. Smith will continue to investigate the paleolimnological record of Middle Beschel Lake....
