Hay River Ice Jam Study
chercheur principal: Hicks, Faye E
Année(s) de permis: 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004
Résumé: The objective of this research project is to study ice processes on the Hay River in order to continue the ongoing development of computer models to predict them. In order to develop realistic models, it is important that the researchers have the opportunity to observe river breakup so as to have a full understanding of the physical context of the historical data. In addition, long term data re...

RADARSAT Observations of River Ice and Flood Patterns in the Mackenzie River Delta
chercheur principal: van der Sanden, Josephus J
Année(s) de permis: 2017 2012 2010 2009
Résumé: To investigate the potential of Canada’s RADARSAT satellites as a tool for the collection of information on (change in) river ice conditions and, during spring breakup, flood conditions in the Mackenzie River Delta. Canada’s RADARSAT satellites have been tasked to acquire images over the Mackenzie Delta since October 2008 to present. Regular data acquisitions will continue into 2010. To facili...

Harnessing River Current Power with Helical Gorlov Turbines
chercheur principal: Katz, Sharon
Année(s) de permis: 2007
Résumé: The goals of this study are: to develop an understanding of water and ice behaviour in sites on the Mackenzie and Great Bear rivers; to obtain knowledge of water speed, depth, current profile, frazil ice and how deep ice may reach into the rivers during the Spring break up; to use this information to determine the feasibility of using Ducted Venturi and Gorlov Helical Turbines (DV-GHT) to harness ...

Evaluation of extreme events (ice jams) and deep scour holes on Mackenzie Delta Channels
chercheur principal: Prowse, Terry D
Année(s) de permis: 2008 2007 2006 2005 2004
Résumé: This is Year 3 of a research project that examines extreme flooding and deep scour holes along the Mackenzie River. Ice jamming has a great influence on channel construction and destruction, formation of deep scour holes in the bed of channels, and flooding of the adjacent delta landscape. Hence, ice jams are of practical concern in the development of infrastructure, ecology of the delta and day-t...

From ice algae to sediments in the frozen arctic seas: the contribution of direct sedimentation and zooplankton grazing on the vertical flux of carbon
chercheur principal: Fortier, Louis
Année(s) de permis: 1994
Résumé: The researchers will be examining small marine organisms (algae, zooplankton and phytoplankton) to determine their influence on global warming. Carbon is necessary for the production of carbon dioxide (CO2), and increase levels of CO2 in the atmosphere can contribute to an increase in the earth's overall temperature. The study will examine how these small marine creatures can reduce carbon level...
