Long term river flow and climate conditions reconstructed from lake sediments
chercheur principal: Lamoureux, Scott F
Année(s) de permis: 2012
Résumé: The research team seeks to obtain sediment cores from two lakes in order to reconstruct past river flow in the region. This work, which builds on similar efforts at "Shellabear" lake, NWT, and work at Cape Bounty (Nunavut), will focus on long term river flow characteristics and the climate factors that control them. The fieldwork involves augering a hole in the lake ice and lowering a tube int...


Biophysical Baseline Studies in Support of the Izok Project
chercheur principal: Trusler, Scott
Année(s) de permis: 2012 2008
Résumé: The objectives of the research studies are the following: refine understanding of baseline conditions; provide input to design mitigation; evaluate potential changes in the environment in relation to the Izok Project; and contribute to the ongoing data collection of the Arctic environment. The Minerals and Metals Group (MMG) Canada team of environmental consultants will collect and review exist...


Environmental Baseline Surveys of the Fortune Minerals Ltd. NICO Project
chercheur principal: Coulton, Daniel
Année(s) de permis: 2017 2016 2014 2013 2012 2011 2010 2009 2008 2006 2005 2004 2003
Résumé: To collect baseline environmental information for future environmental effects monitoring. Surveys will include fish, fish habitat, water and sediment quality, and geochemistry. Equipment for surveys will be limited to standard field measuring and surveying equipment, such as automated water quality monitors, GPS units, motorized inflatable boats, fixed wing aircraft and helicopters. An automat...


Hydrological Studies, Mackenzie Delta Region
chercheur principal: Marsh, Philip
Année(s) de permis: 2023 2022 2021 2020 2019 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006
Résumé: The objectives of this project are: (1) to develop improved understanding of, and ability to predict, snowcover formation and melt, as well as stream discharge in northern regions, and (2) to develop an improved understanding of, and ability to predict, water levels in the lakes and channels of the Mackenzie Delta. These will allow a better understanding of the impact of climate change and/or natu...


Ecological Assessment Field Work for Lue Túé Sulái (the Five Fish Lakes) Candidate Cultural Conservation Area
chercheur principal: Haas, Claudia A
Année(s) de permis: 2012 2011
Résumé: This project is to fill gaps in ecological information on a Candidate Protected Area while it makes its way through the NWT Protected Areas Strategy (PAS) process. This information will be used by the working group to make recommendations on final boundary and management planning for the area. The study will be done at the same time as a study on mercury in fish being conducted by the Dehcho F...


2011 Baseline Studies for Avalon Rare Metals Inc. Proposed Thor Lake Rare Earth Element Project - Surface Water Hydrology and Climate
chercheur principal: Lawson, Nick
Année(s) de permis: 2011 2010 2009
Résumé: The goal of the 2011 Surface Water Hydrology & Climate program at Thor Lake is to collect additional data that describes the existing surface water and climate conditions at the Thor Lake Property. This information is required for continued baseline monitoring, environmental assessments and water management plans for the area. Data obtained will help determine a quantitative description of the ann...


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...


Towards Long-term Monitoring of the CO2 System in Arctic Rivers
chercheur principal: Wang, Zhaohui 'Aleck'
Année(s) de permis: 2012 2011 2010
Résumé: The goal of this research is to initiate time-series measurements of the CO2 system in the Mackenzie River, the major Arctic river in North America. This work will serve as the initial step towards long-term measurements and studies of the impacts of global warming on the CO2 systems in Mackenzie River, its estuary, and adjacent coastal waters. The field campaigns will include both diurnal and...


Hydro-ecological Responses of Arctic Tundra Lakes to Climate Change and Landscape Perturbation
chercheur principal: Wrona, Frederick J
Année(s) de permis: 2011 2010 2009
Résumé: The overall objective of this study is to develop a model that can be used to look at the vulnerability of small arctic lakes and ponds to changing climate. Lake Ice Study: Lakes 5A, 5B and Noell Lake (MAP-2 of the original licence application) will be visited in mid-April to measure lake ice. Holes will be made in the ice using an ice corer. Ice thickness and composition will be determined by...
