Relating changes in snowpack water equivalent and structure to migratory behaviour of the Bathurst Caribou herd
Principal Investigator: English, Michael C
Licenced Year(s): 2016
Summary: 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
Principal Investigator: English, Michael C
Licenced Year(s): 2015
Summary: 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
Principal Investigator: English, Michael C
Licenced Year(s): 2014
Summary: 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
Principal Investigator: English, Michael C
Licenced Year(s): 2013
Summary: 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) ...


Evolution of the snowpack and snowmelt chemistry in the boreal forest and tundra ecosystem
Principal Investigator: English, Michael C
Licenced Year(s): 2012 2010 2009 2008 2007 2006 2005 2004
Summary: This research project has two primary scientific goals which include: 1) Relating ground truthed snowpack data to passive microwave data obtained from satellites through the winter months. This will assist in formulating a empirical relationship between the two datasets which is necessary to improve satellite monitoring of snow water equivalent. 2) Determining the relative importance of snowmel...


Nutrient Availability in Arctic Tundra Soils
Principal Investigator: English, Michael C
Licenced Year(s): 2008
Summary: 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...


Active layer growth and groundwater chemistry, Daring Lake, NWT
Principal Investigator: English, Michael C
Licenced Year(s): 2003 2002 2001 2000
Summary: The crew will fly from Yellowknife to the Tundra Ecosystem Research Station camp on Daring Lake from BHP (Ekati Mine) by helicopter. The research team itinerary consists of: (1) setting up the camp; (2) sampling all of the major streams flowing into Daring Lake for chemistry and instantaneous flow; (3) walking through several basins to decide on an intensive sampling site; and (4) installing dri...


Monitoring Water Levels in the Slave River Delta, NWT
Principal Investigator: English, Michael C
Licenced Year(s): 2001
Summary: 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...


Sediment Sampling on the Slave River Delta, NWT
Principal Investigator: English, Michael C
Licenced Year(s): 2000 1996 1995
Summary: We will arrive at Fort Resolution on or about mid June and re-establish our base camp on Steamboat channel. For each day we are on the delta will be taking samples of sediment from the marshes of the outer delta area with a coring device. At the base camp we will take the core of sediment and section it into 2cm thick sections which will be air dried and shipped south for analysis....


Climatic Variability and Hunting and Trapping Success in the Pond Inlet Region.
Principal Investigator: English, Michael C
Licenced Year(s): 1994
Summary: This study will examine how climate influences the success of hunting and trapping in the Pond Inlet area. The amount of snowfall and air temperature varies from year to year. Increased snowfall may change the normal range of the cariboo and a very cold winter may result in thick sea ice, affecting the distribution of sea breathing holes and number of polar bear found hunting. The researcher wil...
