Upper Cretaceous paleoenvironmental reconstruction of the gateway between the Boreal and Western Interior Seas: The Boundary Creek and Smoking Hills Formations, NWT
chercheur principal: Schroder-Adams, Claudia J.
Année(s) de permis: 2012
Résumé: The main objective of this research project is to improve the stratigraphic framework of the Cretaceous Western Interior Sea region and the understanding of the paleoenvironmental setting of a Cretaceous aged oceanographic gateway between the Boreal Sea and the Western Interior Sea that flooded large parts of North America. The proposed localities have the type section of the two targeted forma...

Quaternary History of the Summer Island area, Tuktoyaktuk Coastlands
chercheur principal: Murton, Julian B
Année(s) de permis: 2008
Résumé: The objective this geological research is to reconstruct climate and environmental history of Richards Island before the last ice age using sediment and peat samples. Fieldwork around the Mason Bay camp will be carried out on foot and a small boat along the coastal bluffs in Summer Island, Richards Island and Hadwen Island. Fieldwork will be carried out by clearing slumped sand from coastal bluff...

Environmental Change in the Western Canadian Arctic Islands
chercheur principal: England, John H
Année(s) de permis: 2012 2010 2009 2008 2007 2006 2005 2004 2003 2002
Résumé: This licence was issued for the application no. 822. The objective of this research is to determine how the environment of Banks Island has evolved during the past several hundred thousand years to present, especially whether Banks Island served as a biological refugia during previous glaciations. The researchers aim to understand and reconstruct the extent and dynamics of past glaciers, past c...

Neoproterozoic Keele Formation, Mackenzie Mountains, NWT and its relation to to major Late Proterozoic glaciations.
chercheur principal: Day, Edith
Année(s) de permis: 2001
Résumé: The research team will be flown from Norman Wells to the base camp at Moose Horn River by helicopter. Moves to fly camps (Stoneknife River and Black Wolf Creek) will also be made by helicopter. The camp will consist of one sleeping tent per team member and one cooking tent. The research team will walk to data collection sites on foot. Data collection will consist of measuring rocks with a rule...

The origin of deformed massive ice, Pleistocene Mackenzie Delta, Western Canadian Arctic
chercheur principal: Murton, Julian B
Année(s) de permis: 1999 1998
Résumé: The main objective of the proposed research is to establish the origin of massive bodies of underground ice at two key massive-ice localities in the Mackenzie Delta area: i) Cliff Point, Liverpool Bay and (ii) near Eskimo Lakes. The research will be carried out by an interdisciplinary team of scientists examining the geology, glaciology and chemistry of the ice and adjacent sediments. The research...

Impact of fire and climate change on a boreal lake
chercheur principal: Moser, Katrina
Année(s) de permis: 1993
Résumé: The researcher will collect samples of sediment and water from small lakes along Highways 5 and 6 between Fort Smith and Hay River. She will be identifying different species of diatoms (small organisms that live in the water) and conducting a number of chemical analyses on the water. Additional data will be collected on the timing of the most recent fire as well as the area's geology and plant c...

Palsa Evolution in Alpine Tundra (PEAT)
chercheur principal: Kershaw, G. Peter
Année(s) de permis: 1992
Résumé: The researcher and his team will determine the current status and contemporary characteristics of palsas (frozen peat mounds), and their environments within this mountainous study area. As well, they will quanititatively describe the processes affecting the evolution of these periglacial features and the potential changes in the status of these and related forms under global change models....
