A multidisciplinary investigation of recovery in Yellowknife area lakes from 50 years of arsenic pollution: What are the factors inhibiting recovery and the biological consequences?
Principal Investigator: Palmer, Mike
Licenced Year(s): 2018 2017
Summary: The overarching objectives of this research are two-fold: 1) to investigate watershed and within-lake abiotic processes affecting the recovery of mine-impacted lakes in the Yellowknife area, including storage and release of arsenic from soils, seasonal dynamics of arsenic export in runoff, and fluxes of arsenic to and from lake sediments; and 2) to investigate the toxicological consequences of...


The Arctic Great Rivers Observatory III
Principal Investigator: Holmes, Robert Max
Licenced Year(s): 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009
Summary: The Arctic Great Rivers Observatory project studies the six largest rivers in the Arctic: the Mackenzie and Yukon Rivers in North America, and the Ob', Yenisey, Lena, and Kolyma Rivers in Russia. We are interested in how climate change is impacting Arctic rivers. The research team will take measurements of the concentration of naturally-occurring chemicals (like carbon and nitrogen) and try to det...


Remediation of the Abandoned Panarctic Satellite F-68 Wellsite at Satellite Bay, Prince Patrick Island, Northwest Territories
Principal Investigator: Krizan, Julia
Licenced Year(s): 2018 2017 2016 2015 2013 2011 2010
Summary: The objectives of the Site Remediation Program (scheduled to be completed in 2018) are to: 1. Remove and dispose of exposed solid waste (including barrels, batteries, debris, wood, other waste and an existing building); and, 2. Construct a contaminated soil and waste containment structure to contain impacted soil excavated from areas at the site. The 2018 Site activities will include several in...


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 ...
