Comparing the snow depths and densities of different habitats in the Beaufort Delta region
Principal Investigator: Kasook, Davonna C
Licenced Year(s): 2017
Summary: The objective is to compare differences in snow depth, density and morphology of a heavily forested site and a tundra site. The Principal Investigator (PI) will study the effect landscape (forest vs. tundra) has on seasonal snow pack evolution and physical properties (density, temperature, snow grain morphology, and stratigraphy) of the snowpack. These results will be compared to historical data (...


Evaluation of Climate Change impacts on Transportation Systems
Principal Investigator: Ford, James D
Licenced Year(s): 2017
Summary: This proposed project will develop critical scientific methods for quantifying transportation vulnerabilities and adaptation opportunities, filling knowledge gaps about transportation vulnerabilities and opportunities for action. Designing and implementing an Arctic vulnerability and adaptation index for transportation systems and infrastructure is crucial to improving the understanding of how ...


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...


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...


Structure, Carbon Dynamics, and Silvichronology of Boreal Forests
Principal Investigator: Osawa, Akira
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004 2003 2002 2001
Summary: The objectives of the research are two-fold. First is to estimate structure, growth, and production of forest stands in northwestern Canada by applying a stand reconstruction and 3D ground-based laser techniques as well as stand measurement, aboveground litter collection, and find root sampling. Second is to examine the relationship between climate change in the high latitudinal regions and the pa...


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 ...


Glacial lakes McConnell and Mackenzie reconstructed from Pleistocene deltas of the Mackenzie River tributaries
Principal Investigator: Froese, Duane G
Licenced Year(s): 2017 2016
Summary: The objective of this project is to investigate the architecture of Pleistocene deltas on the Mackenzie River tributaries, search evidence of high-magnitude discharge events, and collect samples for absolute dating. The research team will investigate the stratigraphic description of sedimentary sections in the river banks cutting through the Pleistocene deltas. Collection of samples are for rad...


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...


Neoproterozoic stratigraphy, Mackenzie Mountains
Principal Investigator: Turner, Elizabeth C
Licenced Year(s): 2017
Summary: This continuing research addresses the history of Earth-surface environments between about 1 billion and 700 million years ago. The objective for 2017 is to complete the sample suite being used by a PhD student (most of the required samples are already in-hand). A base-camp of two people will be deployed by helicopter, and all work done on foot. Working on mountainside rock exposures, the resea...


Community-based long-term monitoring of the Peel River near Fort McPherson
Principal Investigator: Moore, Jonathan
Licenced Year(s): 2017
Summary: The objective of this project is to establish a community-based monitoring program in the Peel River watershed, based in Fort McPherson. Previous research has shown that multiple whitefish ecotypes (non-anadromous, semi-anadromous and anadromous), utilize the Peel River as spawning habitat, but it is unclear how much each ecotype contributes to harvester catches. As different ecotypes occupy d...
