Beaufort Sea Coastal Geoscience Research 2013
chercheur principal: Whalen, Dustin JR
Année(s) de permis: 2016 2015 2014 2013 2012
Résumé: The primary objective of this research is to ensure safe and sustainable industrial and community development by improving the understanding of coastal and nearshore seabed processes and properties. The research provides the means to improve the knowledge of physical conditions in the coastal zone in order to help government agencies, corporations, and local residents understand, mitigate and redu...


Deltaic Lake Sediments as Recorders of Past Carbon Export from Arctic River Drainage Basins
chercheur principal: Vonk, Jorien
Année(s) de permis: 2011 2009 2007
Résumé: The research project goal is to collect surface sediments, bank and levee sediments, particulate sediments and shallow sediment cores from lakes in the Mackenie River Delta, and to evaluate their utility as potential archives of information concerning past permafrost stability by assessing down-core changes in the age and supply of terrestrial carbon. In 2007 and 2009, teams led by Prof. Tim Eglin...


Lake 5A Mesocosm Study - 3rd Amendment to Hydro-ecological Responses of Arctic Tundra Lakes to Climate Change and Landscape Perturbation
chercheur principal: Wrona, Frederick J
Année(s) de permis: 2010
Résumé: The overall objective of the Lake 5A mesocosm study is to better understand the impact of permafrost thaw shoreline slumping (an analogue for a warming climate) on the bottom components of the aquatic food-web in small Arctic tundra lakes in order to better predict the effects of a warming climate on food-web structure, function and productivity. To assess the direct and indirect effects of per...


Circumpolar Flaw Lead (CFL) System Study - Part 1 (Ship-based research)
chercheur principal: Barber, David G.
Année(s) de permis: 2008 2007
Résumé: The Circumpolar Flaw Lead (CFL) system study is designed to examine the importance of climate processes in changing the nature of a flaw lead system and the Arctic marine environment in the Northern Hemisphere, and the effect these changes will have on the marine ecosystem, contaminant transport, carbon fluxes, and greenhouse gases. Using the Canadian Research Icebreaker (CCGS Amundsen), the team ...


Using Tree Rings and Lake Sediment to Reconstruct Streamflow and Climate in the Northwest Territories
chercheur principal: Lamoureux, Scott F
Année(s) de permis: 2002
Résumé: The objective of the research is to supplement and extend instrumental climatological and hydrological records in the NWT using dendrochronology (tree-ring) and varved lake sediment analysis. Transportation to the site will be by charter aircraft from Fo...


Joint services expedition to the Blue Mountains, Ellesmere Island
chercheur principal: Smith, Roger F.
Année(s) de permis: 1994
Résumé: The researchers will conduct a variety of research activities at the study site. Projects include surveys of insects and plants, monitoring glacier movements, collecting data about the area's rocks and soils, assessing changes in the area's climate and environment (using fossils of microscopic marine organisms, chironomids, as indicators), and investigating radio-wave propagation....


Impact of Climatic Change on Earth Surface Processes, Fosheim Peninsula, Ellesmere Island
chercheur principal: Lewkowicz, Antoni G
Année(s) de permis: 1994 1993 1992 1991 1990 1988 1987
Résumé: The overall aim of this research is to establish links between climate and the activity of geomorphic processes so that predictions can be made about the possible impact of any climate change. This project will help to understand how the climate affects the processes that move soil down slopes into rivers and eventually to the sea....


1. Permafrost and Ground Ice of the Expedition Fiord Area; 2. An investigation of the Origin and Nature of Massive Ground Ice on the Fosheim Peninsula
chercheur principal: Pollard, W.H.
Année(s) de permis: 1994 1992 1991 1990 1988
Résumé: This research involves the field investigation of natural exposures of massive ground ice and bodies of surface ice. Sites identified in previous field seasons will be visited and samples of ice, water and sediment will be taken for further analyses. The results of this research will help in the interpretation of climate change and the assessment of both natural and human induced terrain disturban...


Paleontology and Stratigraphy of the Ordovician - Silurian Boundary on Northeastern Cornwallis Island, N.W.T.
chercheur principal: Melchin, Michael J.
Année(s) de permis: 1992 1991 1990 1988
Résumé: The Researcher and his assistants will carry out fieldwork which involves the collection of fossils (most of which are microscopic), rock samples, photographs and notes on the outcrops on northeastern Cornwallis Island. The work is to lead to a better understanding of the environmental changes brought about by changing climate....
