Effects of Climate Change and Landscape Perturbation on Arctic Tundra Lake Water Quality
Principal Investigator: Droppo, Ian G
Licensed 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 ...


The ecology and paleoecology of benthic macroinvertebrates in the Mackenzie Delta region
Principal Investigator: Quinlan, Roberto
Licensed 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
Licensed 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, ...


Predicting climate-driven changes in water quality and biological communities in Gwich'in lakes
Principal Investigator: Gray, Derek K
Licensed Year(s): 2017
Summary: Zooplankton play a key role in aquatic food webs, providing a conduit for the movement of energy between primary producers (algae) and larger organisms such as macroinvertebrates and fish. Therefore, elucidating the impact of permafrost melting on zooplankton is key to gaining a broader understanding of climate change on aquatic ecosystems in Canada’s north. Objectives of this proposed researc...


Remote sensing of Arctic-Boreal surface water
Principal Investigator: Smith, Laurence C.
Licensed Year(s): 2017
Summary: The goal of this project is to measure variations in water surface elevation, inundation extent, permafrost presence/absence, active layer thickness, soil moisture and related variables for lakes, wetlands and rivers in four primary study areas within the Northwest Territories (NWT). Using ground measurements combined with maps of water surface elevation produced by the Air Surface Water and Ocean...


Erosion of old organic carbon in the Mackenzie River Basin
Principal Investigator: Hilton, Robert G
Licensed Year(s): 2017 2013 2011 2010 2009
Summary: The objective of this research is to better quantify the carbon source, age and fate in one of the largest rivers draining the high latitudes. The research team will sample river sediments and waters to establish temporal variability in OC source and age. The team will target high and falling flow (in June) when most sediment and water are exported. The research team will directly measure velo...


The effects of wildfire on diverse aquatic ecosystems of the NWT
Principal Investigator: Tank, Suzanne E
Licensed Year(s): 2017 2016
Summary: The objective of this study is to determine the effect of fire on water quality within the southern NWT landscape. The research team will work across the Taiga Plains and Taiga Shield ecoregions. Differences in landscape between these regions will affect the catchment response to fire. The team will also target catchments with variable permafrost extent, and wetland/lake coverage. The research ...


2017 Tarsuit Caissons Removal Program
Principal Investigator: Clarke, Kim P
Licensed Year(s): 2017
Summary: The objective of this project is to refloat and remove the Tarsuit Caissons from Lease Area 117/D11-3-7. Following their removal, the research team will conduct the following evaluation of the affected site and adjacent area: 1) Side Scan Survey 2) Macro invertebrate Survey A sidescan/multibeam unit (Edgetech 6205, or similar) will be pole mounted on the bathymetry vessel and data will be col...


Long-term perspectives on aquatic ecosystem change with thawing permafrost
Principal Investigator: Korosi, Jennifer B
Licensed Year(s): 2017
Summary: The research team will re-survey 70 lakes originally sampled in 2005/06, to assess how conditions have changed in the intervening decade as thaw slumping has intensified and the Inuvik-Tuktoyaktuk Highway (ITH) was constructed. The team will assess how lake ecosystems responded to past climatic shifts throughout the post-glacial history of these lakes (10,000 years), and use these records to provi...


Environmental Baseline Surveys for the Fortune Minerals Limited NICO Project
Principal Investigator: Schryer, Richard P
Licensed Year(s): 2017 2016 2014 2013 2012 2011 2010 2009 2008 2006 2005 2004 2003
Summary: The objective of this project is to complete a Supplemental Baseline Monitoring Plan (SBMP) for water quality, fish population and benthic invertebrate programs. The SBMP contains two major study areas: Burke Lake, Reference Lake and the Marian River. Burke Lake will be the exposure area and Reference Lake will serve as the reference area for the SBMP. The exposure area for the Marian River wat...
