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...


The ecology and paleoecology of benthic macroinvertebrates in the Mackenzie Delta region
Principal Investigator: Quinlan, Roberto
Licensed Year(s): 2017 2016 2015 2014 2013
Summary: This study will examine the effects of permafrost and flooding on the ecological structure and carbon exchange of contrasting lakes in the Mackenzie River Delta. Patterned ground marked by ice-wedge polygons is formed by freezing and thawing of the soil, which forms cracks into which ice can spread and cause the soil to uplift. These processes have effects on the hydrology and water chemistry of a...


Investigating the cumulative effects of environmental change and human activity in the Tathlina watershed
Principal Investigator: Laidlaw, Shawn
Licensed Year(s): 2013 2012
Summary: The purpose of this project is to: 1) coordinate monitoring and research efforts in the watershed between the community, government, and universities; 2) understand current aquatic health of the watershed using water quality, macroinvertebrates, aquatic furbearers and fish as indicators of ecosystem health; 3) understand historical environmental change and contaminant loading in the watershe...


Paleohydrology and paleoecology of the Slave River Delta
Principal Investigator: Wolfe, Brent BBW
Licensed Year(s): 2007 2006 2005 2004 2003 2002
Summary: This research program focuses on high-resolution reconstruction of past hydrology, ecology and climate of the Peace-Athabasca (PAD) and Slave River deltas (SRD) from natural archives, including lake sediments and tree rings, supported by comprehensive field-based studies of modern hydrology, limnology and aquatic ecology. The PAD and SRD have broad ecological and cultural significance and are ecos...


Paleoecology of Mercy Bay reefs, Frasnian, Banks Island
Principal Investigator: Edinger, Evan N
Licensed Year(s): 2001 2000
Summary: The Devonian patch reefs of Mercy Bay, Banks Island are important as an example of fossil coral reefs that may also be able to provide insight into the nature of a reef ecosystem immediately before a time of global reef collapse. The researcher will fly to the Parks Canada cabin at Mercy Bay and will use a helicopter to travel to 5 camps and stay at each fly camp for a period of 2 days. Equipmen...


Freezing history and depositional setting of massive ground ice in the Canadian High Arctic
Principal Investigator: Bell, Trevor
Licensed Year(s): 1993 1990 1988
Summary: This study will provide a better understanding of permafrost conditions in the high arctic as well as the environmental conditions that lead to permafrost formation. Study sites include the Fosheim Peninsula on Ellesmere Island and May Point and Mokka Fiord on eastern Axel Heiberg Island....


Upper Silurian reef mounds at the Douro-Devon Island formational boundary, Devon and southwestern Ellesmere Islands
Principal Investigator: Dixon, O.A.
Licensed Year(s): 1993 1992 1990 1988
Summary: In the Arctic Islands, we are studying rocks and the fossils found within these rocks that were formed more than 400 million years ago in warm tropical seas. This study is expected to help in describing the temperatures, climate and water depths of these ancient seas. We are also studying the types of fossil corals and sponge-like animals that are not present in our seas today....


Evolution of High Latitude Floras
Principal Investigator: Basinger, James F.
Licensed Year(s): 1994 1993 1992 1991 1990 1989 1988 1987
Summary: The researcher and his team will continue the study of the evolution of plants and climate in the very high latitudes, and will continue to assemble an extensive collection of fossil plants from northern Canada....


Quaternary Geology, West-Central Axel Heiberg Island
Principal Investigator: Lemmen, Donald
Licensed Year(s): 1991
Summary: The Researcher will map, describe, explain the surficial deposits and geomorphology and study glacial history and relative sea level changes. This will involve mapping and surveying as well as the collection of small samples for sedimentological, geochemical and paleoecological analysis....


Quaternary Geology, South Shore of Great Slave Lake
Principal Investigator: Lemmen, Donald
Licensed Year(s): 1991 1990
Summary: The Researchers will collect small samples of surficial materials for sedimentological, geochemical and paleoecological analysis. They will map, describe and explain the unconsolidated deposits, landforms, permafrost and organic cover and study patterns of glacial dispersal and drift geochemistry....
