chercheur principal:Whalen, Dustin JR Année(s) de permis:201620152014
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...
chercheur principal:Vonk, Jorien Année(s) de permis:
2011
20092007 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...
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...
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 ...
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...
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....
chercheur principal:Lewkowicz, Antoni G Année(s) de permis:19941993
1992
1991199019881987 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....
chercheur principal:Pollard, W.H. Année(s) de permis:19941992
1991
19901988 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...
chercheur principal:Melchin, Michael J. Année(s) de permis:19921991
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....
