Nutrient and contaminant status in the wetlands of the Slave River Delta
Principal Investigator: Doig, Lorne
Licenced Year(s): 2019
Summary: Through this research the team will answer the following questions: 1. From the outer Slave River Delta (SRD) to the apex of the SRD, what is the current status of nutrients and contaminants in SRD wetland ecosystems? 2. How do trace elements (e.g., mercury) move through SRD wetland food webs? 3. How does water source affect the availability of nutrients and trace metals in SRD wetlands? Wet...


Howards Pass Access Road (HPAR) Proposed 2019 Baseline Programs
Principal Investigator: Morison, Stephen R
Licenced Year(s): 2019
Summary: Proposed surface water and sediment quality and quantity programs involves two rounds of field sampling proposed in mid-July to early August and in late September 2019, to capture typical summer stream flows and low stream flow conditions. Each field program may take between eight to ten days. The objectives of the programs are to confirm and update the fluvial geomorphic classification of each st...


Investigating the water quality of runoff from different terrain types
Principal Investigator: Hille, Erika C
Licenced Year(s): 2019 2018
Summary: The objectives are: 1) to examine how the water quality of streams varies spatially and determine what drives these differences (i.e., latitude, vegetation, surficial geology); and, 2) to examine how the water quality of streams varies temporally and determine what/how seasonal changes in water flow control water quality. The research team will collect water samples from a suite of study site...


The Arctic Great Rivers Observatory III
Principal Investigator: Holmes, Robert Max
Licenced Year(s): 2019 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. The research team are interested in how climate change is impacting Arctic rivers. The team make measurements of the concentration of naturally-occurring chemicals (like carbon and nitrogen) and try to de...


Investigations of the water cycle and hydrological processes of the subarctic Canadian Shield
Principal Investigator: Spence, Christopher
Licenced Year(s): 2017 2016 2012 2011 2010 2009 2008 2007
Summary: It is the objective of this research to determine the water cycle processes acting in watersheds that could affect the streamflow response and water chemistry of Taiga Shield streams. The proposed work will take place within a research basin framework. The proposed watershed, the upper reaches of Baker Creek, is a typical Canadian Shield stream that drains 150 km2 into Great Slave Lake. There ...


The effects of fire on diverse aquatic ecosystems of the NWT
Principal Investigator: Tank, Suzanne E
Licenced Year(s): 2017 2016
Summary: The objective of this study is to determine the effect of fire on water quality within the southern Northwest Territories landscape. The research team will work across the Taiga Plains and Taiga Shield Ecoregions, because it is believed that differences in landscape between these regions will affect the catchment response to fire. The research team will also target catchments with variable permaf...


Erosion of carbon from high-latitude peatlands: Isotopic insight into fluvial transfer in the Mackenzie River Basin
Principal Investigator: Hilton, Robert G
Licenced Year(s): 2017 2013 2011 2010 2009
Summary: The objectives of this research project are to correct for fossil particulate organic carbon (POC) input to the Mackenzie River, and to determine the loci of peatland organic carbon (OC) erosion and flux to the fluvial system. WATER VELOCITY TRANSECT At each sampling location, an Acoustic Doppler Current Profiler (ADCP) will allow the research team to determine bathymetry, water velocity trans...


Degradation of dissolved organic carbon in Mackenzie Delta lakes and river channels
Principal Investigator: Tank, Suzanne E
Licenced Year(s): 2013 2012
Summary: This study will examine the solar degradation of riverine dissolved organic carbon (DOC) to carbon dioxide (CO2) throughout the Mackenzie River Delta. During the spring runoff peak just before summer solstice, ice-jam flooding inundates the Delta with river water, which spreads out in a relatively thin layer over an extended area and is exposed to 24-hour Arctic sunlight. This water is then slowly...


An investigation of arsenic speciation and toxicity in Baker Creek sediments from Giant Mine in the Northwest Territories, Canada
Principal Investigator: Nash, Tyler J
Licenced Year(s): 2012
Summary: The objective of this research project is to assess the sediment quality of Baker Creek. This will be achieved by analyzing factors influencing arsenic mobility from sediments to overlying water and assessing the toxicology of the sediments using exposure tests on indicator organisms. Core samples of Baker Creek sediments will be taken by the researchers using aluminum pipes driven into the gro...


Bosworth Creek Monitoring Project
Principal Investigator: Guthrie, Glen H
Licenced Year(s): 2011 2010 2009 2008 2007 2006
Summary: Year Four: The Bosworth Creek Monitoring Project has become permanently embedded in Mackenzie Mountain School’s Experiential Science 30 Program and will continue to provide professional development for local youth through associations with academic and industrial institutions. The project will complete baseline biological and chemical data and investigate new sources of ground water that may be t...
