Effects of permafrost disturbances on terrestrial and aquatic ecosystems, Banks Island, NWT, Canada
Principal Investigator: Lacelle, Denis
Licenced Year(s): 2015
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...


Cumulative Impacts Monitoring of Aquatic Ecosystem Health of Yellowknife Bay, Great Slave Lake
Principal Investigator: Chételat, John
Licenced Year(s): 2015
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 ...


2015 Mackenzie Valley Highway Hydrotechnical Field Investigation
Principal Investigator: McGregor, Robyn
Licenced Year(s): 2015
Summary: The objective of the spring 2015 hydrotechnical assessment is to continue to assess the major watercourses (approximately 29) in the Gwich'in Settlement Area along the proposed Mackenzie Valley Highway alignment that were identified in the preliminary work completed in the Project Description Report submitted in May 2011. The spring 2015 field survey is planned to observe the proposed crossings...


Water Quality Assesment of Pump lake and chain lakes in Aklavik
Principal Investigator: Gordon, Andrew B.T
Licenced Year(s): 2015
Summary: The objectives are to; 1) Collect surface water samples of several connected lakes, 2) Analyze the water samples for temperature, salinity, pH, TSS, nutrient (nitrogen and phosphorus) and coliforms, 3) Interpret data and present information to the community Lakes will be accessed by walking or snow machine. Five sampling holes will be randomly chosen along a 500 m transect oriented from magneti...


Edzo Water Intake - Aquatic Assessment
Principal Investigator: Lavictoire, Michelle L
Licenced Year(s): 2014
Summary: To gather site specific information and habitat description at and near the existing water intake in order to complete an impact assessment for proposed in-water works (described in the rationale) Site investigations would include habitat mapping and fish community sampling. The research team are assuming the fish community information will be required as it is understood at this time that no s...


Development of small bodied fish species as a biomonitoring tool to detect environmental change in northern rivers
Principal Investigator: MacLatchy, Deborah
Licenced Year(s): 2014 2013
Summary: The objectives of this research project are to: 1. Collect and sample small bodied fish species (emerald and spottail shiners) at the same two sites as Sept 2013 (sewage effluent outflow pipe at Fort Smith and upstream near the boat launch) and at other accessible, habitat-appropriate sites (mouth of Salt River, exposed bitumen sites, above the rapids). The fish collections will be conducted acc...


Bathymetry, Aquatics and Fisheries Data Collection for the Potential North Diversion of Baker Creek, Giant Mine Remediation Project
Principal Investigator: Sibbald, Carey
Licenced Year(s): 2014
Summary: The primary objectives of this research program are to collect baseline data on the bathymetry and depth contours, water chemistry, limnological profiles, sediments, and benthic biota, fish presence and habitat. The Bathymetry field program will be conducted in August 2014, prior to the Aquatics and Fisheries field programs. Data from the bathymetry field program is required to finalize samplin...


Permafrost Disturbance Susceptibility Mapping
Principal Investigator: Lamoureux, Scott F
Licenced Year(s): 2014
Summary: The goal is to produce permafrost disturbance susceptibility maps for the region surrounding Sachs Harbour identifying areas with low, moderate and high susceptibility to future permafrost disturbance. A 25 km radius around Sachs Harbour will be systematically mapped to identify and map permafrost disturbances. GPS will be used to map the perimeter of identified permafrost disturbances. Soil s...


Cumulative impacts of metal deposition in the NWT: Using lead isotopes to trace local, regional and long-range sources
Principal Investigator: Chételat, John
Licenced Year(s): 2014 2013
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...


Sediment core studies in Great Slave Lake
Principal Investigator: Evans, Marlene S
Licenced Year(s): 2014
Summary: The objectives of this research project are to collect a series of sediment cores in the West Basin of Great Slave Lake to investigate time trends in various chemicals of interest including mercury, mercury isotopes and persistent organic contaminants. In late-March 2014, the research team will collect sediment cores at 3-4 locations on Great Slave Lake (West Basin, offshore Slave River). An 8...
