Summary: This licence has been issued for the scientific research application No.5328. The objective of this project is to collect water quality data from regionally-representative lakes that can inform resource management decisions on cumulative impacts within the Northwest Territories (NWT). Using a computer program the research team will select 30 lakes within the Daring Lake area based on expect...

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...

Summary: Water quality monitoring equipment has been deployed at over 42 sites across the NWT to address community concerns. Community members were trained to use the following equipment: •YSI sondes: sit in the water and measure basic water quality parameters every 2 hours for up to 3 months. Analysis undertaken at ENR. •Grab water samples: measure basic parameters, nutrients, physicals, major ions,...

Summary: This project will determine what information Regulators require about cumulative effects or conditions in order to make informed decisions regarding development impacts to water quality in the NWT, and whether and how that information is, or can be, provided through NWT Cumulative Impacts Monitoring Program (CIMP) or other agencies responsible for monitoring. The objectives are as follows: 1)...

Summary: The objective of this research is to establish a community-based monitoring program in the Peel River watershed, based in Fort McPherson. Previous research has shown that multiple whitefish ecotypes (non-anadromous, semi-anadromous and anadromous, utilize the Peel River as spawning habitat, but it is unclear how much each ecotype contributes to harvester catches. As different ecotypes occupy d...

Summary: The objective of this project is to conduct ongoing monitoring and assessment programs, including areas in the Mackenzie River Special Management Zone (SMZ), for surface water. Surface water samples will be collected from selected lakes, ponds, rivers, and streams. Selected water bodies in EL470 have already undergone bathymetric assessment and sampling. ConocoPhillips will communicate, in ...

Summary: Thaw slumps are one of the most dramatic thermokarst features in permafrost regions. The number of thaw slumps on Banks Island has more than tripled in recent decades and it is likely that this change is altering terrestrial and aquatic ecosystems. This multidisciplinary research project investigates the short- (1960s-present day) and long-term (Medieval Warm Period to today) impacts of permafrost...

Summary: The main objective of this study is to investigate the ecosystem health of Yellowknife Bay. We will address the following questions through a field study: 1) What is the quality of water and sediment in Yellowknife Bay (focusing on metals, nutrients and cyanobacteria)? 2) What are the main sources and transport pathways of metals accumulating in the food web of Yellowknife Bay? 3) How much of ...

Summary: Yellowknife Bay on Great Slave Lake is a water body of cultural, subsistence and recreational importance for the Yellowknives Dene First Nation (YKDFN) and residents of Yellowknife. The ecosystem health of Yellowknife Bay has been impacted by historical mining releases of metals (particularly arsenic), as well as long-range atmospheric transport of metals such as mercury from far-away human emissi...

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) ...
