Climate change and the potential socio-economic effects on communities resulting from reducing winter road access
chercheur principal: English, Michael C
Année(s) de permis: 2021
Résumé: This licence has been issued for the scientific research application No.4952. The overall goal of this research project is to evaluate how citizens of two Northwest Territory communities, Wekweeti and Aklavik, view the vulnerability of the winter roads serving each community to climate warming and how these impacts may affect community well being with respect to socio-economics and culture. Ove...


Relating changes in snowpack water equivalent and structure to migratory behaviour of the Bathurst Caribou herd
chercheur principal: English, Michael C
Année(s) de permis: 2016
Résumé: The objectives are to work with local residents of Wekweeti to understand how changes in the annual snowpack may impact caribou. The idea is that with increased incursions of warm southern air into the subarctic during winter that snow crusts and ice lenses may be created in the snowpack and as a result increase the energy expenditures of the caribou when foraging for food at the base of the snowp...


DOC in surface waters in the NWT; implications of a changing climate
chercheur principal: English, Michael C
Année(s) de permis: 2015
Résumé: This research focusses upon dissolved organic carbon (DOC) quantity and quality from a suite of hydrological environments underlain by discontinuous permafrost. The research looks to better understand how water quality will be influenced by a warming climate, with specific attention to DOC, by analysing historical water quality data (30 years) from three local rivers (Yellowknife, Cameron, and Mar...


Long term and current variability in sources and sinks of carbon and nitrogen in terrestrial and aquatic ecosystems underlain by discontinuous and continuous permafrost
chercheur principal: English, Michael C
Année(s) de permis: 2014
Résumé: The objectives of this research project are: 1. to extract sediment cores from three different regions of the Northwest Territories namely: the low arctic tundra (continuous permafrost-Daring Lake), Taiga Shield northern boreal (widespread discontinuous permafrost-Wekweeti), and Taiga Shield boreal (sporadic discontinuous permafrost-Baker Creek Watershed) which provide the research team with a re...


Variability in peat plateau energy balance and water chemistry along a warming gradient
chercheur principal: English, Michael C
Année(s) de permis: 2013
Résumé: This research is physically based on a peat plateau and a peat bog, both close to Yellowknife. There are two primary objectives to this research. The first involves quantifying surface energy balances in areas where degradation of peat is pronounced and where it is not. Suprapermafrost water from the degraded and non-degraded sites will be analyzed for nutrients and dissolved organic carbon (DOC) ...


Nutrient Availability in Arctic Tundra Soils
chercheur principal: English, Michael C
Année(s) de permis: 2008
Résumé: This licence is issued for the scientific research application # 876. The objective of this research is to determine the impacts of predicted soil warming scenarios for the arctic on the availability of phosphate, nitrate-nitrogen and ammonium, which are important soil nutrients. The field portion of this research will consist of two weeks of collecting soil data and gauging and sampling (f...


Assessing snowpack water equivalent distribution in the Exeter-Yamba-Daring Lake catchment, Coppermine River Basin, NWT using in-situ snow surveys and various scales of passive microwave remote sensing data
chercheur principal: English, Michael C
Année(s) de permis: 2012 2010 2009 2008 2007 2006 2005 2004
Résumé: This project would improve the national snow water equivalent (SWE) monitoring capabilities by acquiring the necessary data to estimate SWE in the snow covered tundra environment. Transportation for local surveys will be by snowmobiles. Regional surveys...


Tundra Hydrology and Chemistry, Daring Lake, NWT
chercheur principal: English, Michael C
Année(s) de permis: 2003 2002 2001 2000
Résumé: The objectives of the research are to examine how changes in active layer depth influence groundwater and surface water chemistry in two subbasins of the Daring Lake basin in the headwaters of the Coppermine River Basin. In addition, a snow survey of th...


Monitoring Water Levels in the Slave River Delta, NWT
chercheur principal: English, Michael C
Année(s) de permis: 2001
Résumé: The research team will be based in Ft. Resolution. Transportation includes aircraft from Toronto to Edmonton to Hay River. Transportation in the field will be by truck and boat. The research team will operate from a base camp previously established on Steamboat Channel (a camp we originally established in 1977 when this work originally started). Water level recorders will be established at six sit...


Hydrology and geomorphology studies on the Slave River Delta, N.W.T.
chercheur principal: English, Michael C
Année(s) de permis: 2000 1996 1995
Résumé: The researchers will examine three things. The first is areas of landform change since 1977. Landforms will be surveyed and sediment sampled in order to measure how much sand, silt and clay are in the deposits. Second, the researchers will analyze the sediment for different chemicals wihich originate from the Slave River and third, measure the elevations of channels along their entire length, me...
