Correlation of water quality parameters of a disturbed slump and an undisturbed river bank on the east branch of the Mackenzie River.
Principal Investigator: Hansen, Jeremy R
Licenced Year(s): 2017
Summary: The objective is to investigate a disturbed slump site and an undisturbed river bank to measure and compare what is possibly melting/flowing/leaching into the river system possibly due to climate change. Physical descriptions of both sites combined with temperature, potential of hydrogen (pH), TSS (total suspended solids), TDS (total dissolved solids), and turbidity will be collected, analysed, an...


Understanding the potential impact of metals in aquatic systems.
Principal Investigator: McGeer, Jim
Licenced Year(s): 2017
Summary: The objectives of this research are to evaluate the relative sensitivity of northern aquatic invertebrates and northern ecosystems in comparison to southern species and environments. The focus of comparisons is in relation to the toxicity of metals. Three types of sample collections are proposed. These would be done at selected sites along the Ingraham Trail (highway 4) east of Yellowknife. The...


Temperature and oxygen concentrations in Dolomite (Airport) Lake
Principal Investigator: Lord, Sarah
Licenced Year(s): 2017
Summary: The purpose of this study is to directly measure temperature and dissolved oxygen concentrations in Airport Lake throughout the year, and to find out if low oxygen levels are limiting the growth rate of lake trout population in this lake. Repeated sampling at the same locations on the lake during fall, winter, spring, and summer will show whether oxygen levels are adequate for optimal lake trout t...


2017 Baseline monitoring of marine productivity and oceanography spanning the Northwest Passage using ships of opportunity
Principal Investigator: Fisher, Jonathan AD
Licenced Year(s): 2017 2016
Summary: The first objective is to collect, analyze and report the findings from station-based and continuous plankton sampling and data on depth, temperature and salinity in the upper water column throughout Canada’s Northwest Passage. As a contribution to marine climate change research, this program will provide northern communities with the first regional-scale view of marine productivity—thereby provid...


Effects of Climate Change and Landscape Perturbation on Arctic Tundra Lake Water Quality
Principal Investigator: Droppo, Ian G
Licenced Year(s): 2017
Summary: The overall goal of this study is to obtain information, through laboratory experiments (rainfall simulator; 2m annular flume) on sediments collected from retrogressive permafrost thaw shoreline slumps affecting numerous Arctic tundra lakes in the Mackenzie Upland Region east of the Mackenzie Delta, on the physical processes through which slump material is transported and delivered to a receiving ...


EL494 Surface Water Monitoring Program 2016-2018
Principal Investigator: von Kuster, Jenica
Licenced Year(s): 2017 2016
Summary: The study is to continue to establish natural variations in the surface water conditions within the Exploration Licence (EL 494) area and monitor potential impact of oil and gas exploration activities. Surface Water Quality Sample Collection: Collect surface water samples once, during August 2017, from a reduced number of sampling locations targeted near areas where exploration activities have...


The ecology and paleoecology of benthic macroinvertebrates in the Mackenzie Delta region
Principal Investigator: Quinlan, Roberto
Licenced Year(s): 2017 2016 2015 2014 2013
Summary: The objectives of our study are to 1) establish the importance of lake connectivity in determining the community composition and species richness of the invertebrate community of a lake, and the contribution of lakes of differing connectivity to the regional diversity of the Mackenzie Delta, 2) characterize the response of invertebrate communities to changing peak flood levels to allow prediction ...


NATCL Cantung 2017 EEM Program
Principal Investigator: Carson, Richard J
Licenced Year(s): 2017 2015
Summary: The objectives are to evaluate if there are differences in biological parameters among study sites and between years at the Tungsten Mine site; as well as to determine whether observed differences from the most recent (2015) Environmental Effects Monitoring study are still present and whether any differences are the result of mining practices. The study objectives are to evaluate fish health, ...


TERRE-NET: Controls on the Release of Contaminants from Gold Tailings at the Giant Mine, Yellowknife, NT
Principal Investigator: Blowes, David W.
Licenced Year(s): 2017
Summary: The objectives of this research project are to: 1) determine the magnitude and rate of release of arsenic and other toxic elements from the Giant Mine tailings to groundwater; 2) evaluate remediation alternatives for tailings management, including the effects of proposed engineered covers; and, 3) apply novel characterization techniques to understand the mechanisms controlling arsenic release. ...


Understanding changes in aquatic ecosystem health and water quality in the Fort Good Hope – Ramparts Area
Principal Investigator: Gurney, Kirsty E.
Licenced Year(s): 2017
Summary: This project aims to build community partnerships, identify field sites, and develop and implement sampling protocols for long term, community-based, monitoring of wetland ecosystems near Fort Good Hope. Whereas some wetlands in the study area have 1) already been, or 2) are likely to be, impacted by a wide range of industrial activities, including development of oil and gas and associated inf...
