Legacy arsenic pollution in Yellowknife Bay sediments: An assessment of its long-term fate under a changing climate
Principal Investigator: Chételat, John
Licenced Year(s): 2018
Summary: This study will assess the present-day and future stability of legacy arsenic contamination stored in Yellowknife Bay sediments that originated from local gold mining activities. Using a combination of quantitative methods (field measurements, laboratory experiments, paleolimnology and mass balance modelling), the research team will estimate the diffusion of arsenic from sediments to overlying wat...


Vegetation Productivity on the Bathurst Caribou Range
Principal Investigator: Danby, Ryan K
Licenced Year(s): 2018
Summary: The two main objectives are: to map changes in vegetation productivity on an annual basis across the Bathurst caribou herd’s range using satellite imagery obtained from NASA’s MODIS sensor (available since 2000) and analyze these data to identify where the most significant changes have occurred; and to collect and analyze data on the growth, establishment, and mortality of shrubs and trees over th...


NASA ABoVE Airborne Campaign 2018 Addendum
Principal Investigator: Miller, Charles E
Licenced Year(s): 2018 2017
Summary: The extended Arctic-Boreal Vulnerability Experiment (ABoVE) Study Area includes most of northwestern North America west of Hudson Bay and north and east of the coastal mountain ranges. The core study area includes 4 jurisdictions: Alaska, Yukon, Northwest Territories, and Nunavut. It encompasses the variability in the key types of ecosystems that are both unique to arctic and boreal regions in Nor...


The Semantics of Relative Clauses in Tlicho Yatii
Principal Investigator: Hucklebridge, Sherry
Licenced Year(s): 2018
Summary: The specific focus of this study is on relative clauses in Tlicho Yatii. The term `relative clause' is used to refer to clauses that define, identify or describe nouns. For example, in the sentence `The students who Ann liked got an A', the clause `who Ann liked' is a relative clause. Unlike English, Tlicho Yatii has few adjectives, and relative clauses are used for all description of nouns in the...


Con Mine Phase 6 EEM - Periodic Monitoring
Principal Investigator: Irving, Elaine
Licenced Year(s): 2018 2015 2012 2009 2007
Summary: The objective of the study is to carry out the third year of periodic monitoring of fish and benthos at the determined study locations; Jackfish Bay (exposure area), Horseshoe Island Bay (reference area for fish survey) and Kam Bay (reference area for the benthos survey), to determine if treated Con Mine effluent is affecting fish and fish habitat. The study has been designed to replicate the stud...


Application of passive seismic methodologies to the determination of overburden thickness in a permafrost-rich environment
Principal Investigator: McPeak, Sara E
Licenced Year(s): 2018
Summary: The objectives of this project are to test if passive seismics can be used to map the thickness of overburden in a permafrost-rich environment; and, to compare overburden thickness derived from passive seismic data and known overburden thickness from drilling. This project will test to see if the earth’s natural vibration can be used to determine how much sand, gravel, soil and permafrost are a...


SAMMS: Sub-Arctic Metal Mobility Study
Principal Investigator: Wolfe, Brent BBW
Licenced Year(s): 2018
Summary: The seven-year objective of Sub-Arctic Metal Mobility Study (SAMMS) is to identify, quantify, and predict mobility of natural-source and legacy mine-source metals in soil, wetlands, and lake sediments that extend from former, present, and planned mine sites currently and as climate change alters the quantity and quality of dissolved organic matter produced and exported in subarctic NWT watersheds....


Bryophytes of southwest Northwest Territories waterfall areas
Principal Investigator: Doubt, Jennifer
Licenced Year(s): 2018
Summary: The objective is to increase knowledge of bryophytes (e.g., mosses, liverworts) and (incidentally, where possible) lichens in the Northwest Territories. Waterfall areas can offer a wide diversity of microhabitats (featuring a large variety of substrates, moisture and light levels, and exposures) within a relatively small area. Bryophyte species and communities are often associated with specific...


Impacts of climate change on wildfire risk in boreal forests in the Northwest Territories
Principal Investigator: Asselin, Hugo
Licenced Year(s): 2018
Summary: The three main objectives of this research are: 1) to reconstruct the multi-century history of wildfire and vegetation in the Northwest Territories by analyzing charcoal contained in lake sediments; 2) to establish the links between recent fire activity and climatic data by studying tree growth rings (annual resolution); and, 3) to combine this scientific knowledge to indigenous knowledge obtained...


Wind Energy Monitoring at Snare Hill
Principal Investigator: Dares, Matthew J
Licenced Year(s): 2018
Summary: The objective of this wind monitoring proposal is to continue to measure the wind energy potential at CN Hill (approximately 130 km from Yellowknife) until the site is next serviced and the equipment removed. This is part of an alternative energy study for the Yellowknife area. Wind data will be collected using instruments that measure wind speed, direction, and temperature. Sensors are already in...
