Résumé: Uniform permafrost and ground surface temperature measurements are one of the more important databases for long-term climatic study as well as remote sensing ground truthing data. Consistency in sensor depth, casing and drilling methods helps in comparison of the spatial and temporal distribution of the permafrost and seasonal conditions. The proposed partnership with the schools aids continuous m...

Résumé: The objective of this research is to understand how climate change is affecting permafrost in the western Arctic, particularly in the outer Mackenzie delta. The research team also intends to investigate the ice content of the ground and how this may affect terrain stability. The research team wishes to study changes in ground temperature at various locations in the western Arctic, ranging from Her...

Résumé: Long term goals of this research: 1. Identify and quantify the physical, chemical and ecological processes that affect contaminant transfer in Arctic aquatic food webs in response to observed and predicted Climate Variability & Change (CVC) in the Husky Lakes Watershed (HLW). 2. Provide people and regulators of Inuvik and Tuktoyaktuk with tools to effectively monitor selected highly valued compo...

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...

Résumé: The objective of this study is to measure the changing volume of the ice cap, to maintain an automatic weather station and to measure how much the climate is changing. The snow sampling tells how clean the snow and thus the air above it and whether it is changing. There is an automatic weather station on the ice cap, which provides a year-round record of snowfall and temperature. Because of we...

Année(s) de permis: 2012 2011 2010
Résumé: The goal of this project is to take part in the establishment of long-term observation network to measure concentrations of two important greenhouse gases (ozone and carbon dioxide) as well as bromine oxide, a key chemical reagent determining the presence of ozone accompanied with full set of meteorological data and detailed geographic information across the Arctic Ocean and Hudson Bay. Data acqu...

Année(s) de permis: 2011 2010
Résumé: There are two objectives associated with this research. The first is to establish vegetation and permafrost monitoring sites in the region. The establishment of these permanent monitoring sites will improve our understanding of base-line environmental conditions in the region. The second goal for the 2010 monitoring season is to build local capacity for monitoring vegetation and permafrost in t...

Résumé: The central aim of the ArcticNet marine-based research program is to study on a long-term basis how climate induced changes are impacting the marine ecosystem, contaminant transport, biogeochemical fluxes, and exchange processes across the ocean-sea ice-atmosphere interface in the Canadian Arctic Ocean. Ultimately, the knowledge generated from this multi-year program will be integrated into region...

chercheur principal: Moorman, Brian J
Année(s) de permis: 2010
Résumé: The main objective of this study is to establish the degree of impact and spatial extent of specific oceanic storm surges within the coastal Mackenzie Delta over the past 40 years. This investigation will be completed by analyzing remote sensing imagery to create multiyear change maps. The resulting maps will then be correlated to historic water level and climate data and verified by field samples...

Année(s) de permis: 2011 2009
Résumé: The main aim of these weather and air quality studies is to improve the understanding of the processes in the Arctic atmosphere and to use these measurements to improve the performance of regional and global climate models of the Arctic. The aim of the sea ice studies is to obtain a snapshot of ice thickness in a vast region of the Arctic, and to create an inventory of Arctic sea ice volume. ...
