NASA ABoVE Airborne Campaign 2019
Principal Investigator: Miller, Charles E
Licensed Year(s): 2019 2018 2017
Summary: This licence has been issued for the scientific research application No.4499. This airborne field campaign will link studies conducted on the ground with data collected through satellite remote sensing, enabling a deeper understanding of the vulnerability and resilience of these ecosystems, and how people within and beyond this region are responding to change. The ABoVE airborne campaigns can p...


Using Novel Technology to Survey Methane Emissions in the Mackenzie Delta
Principal Investigator: Risk, Dave
Licensed Year(s): 2019
Summary: The research team will use the newly develop ExACT (Emissions Attribution via Computational Techniques) system, a completely novel and innovative approach to survey gas emissions from natural and manmade sources. ExACT consists of computer algorithms applied to geo-located multi-gas data collected during vehicle-based surveys. Data collection involves a combination of multi-gas analyzers, targetin...


Nutrient and contaminant status in the wetlands of the Slave River Delta
Principal Investigator: Doig, Lorne
Licensed 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...


The Exeter Lake esker: Nature and origin of North America's longest esker
Principal Investigator: Bilak, Grayson S
Licensed Year(s): 2019
Summary: This research project aims to determine the nature and origin of the Exeter Lake esker, and focuses on further constraining key parameters for exploration purposes. Eskers are deposited in dynamic glacial environments, and many factors need to be considered during exploration including but not limited to; how far has the sediment traveled from the original source, how large of an area is the esker...


Marine Geohazard and Environmental Studies in the Southern Beaufort Sea
Principal Investigator: Côté, Michelle
Licensed Year(s): 2019 2018
Summary: The goals of this research are to ascertain the formation of marine pockmarks, which are circular depressions on the sea floor thought to have formed from the release of methane gas. The hypothesis is that these features are actively releasing gas to the atmosphere and that they are formed from degrading or thawing offshore permafrost. The research team intend to document the seabed characteris...


Terrain Mapping and Surficial Material Sampling - East Credit Lake
Principal Investigator: DesRosiers, Patrick
Licensed Year(s): 2019
Summary: The objectives of this project are: 1. to create a map of the area that displays the different surficial materials, landforms, and processes that have shaped the earth’s surface; 2. to determine the glacial history of the area by making observations of ice flow indicators; 3. to collect samples from a variety of different surficial materials deposited by glaciers; 4. to analyze the samples in ...


Shale Basin Evolution in Central NWT (2019)
Principal Investigator: Terlaky, Viktor
Licensed Year(s): 2019
Summary: The objective is to scope the Imperial Formation in order to develop a more extensive future study of this formation, and to sample the sites for conodont fossil bearing carbonates in order to better age date the Horn River Group deposits. At each site the rock exposure will be photographed in detail. At Mountain River and Gayna Gorge the outcrop will be sampled for conodont fossil bearing car...


NSERC Canadian Lake Pulse Network: more than 660 Canadian lakes sampled over three summers.
Principal Investigator: Huot, Yannick
Licensed Year(s): 2019
Summary: The objective of this project is to evaluate and compare complex and abundant lake ecosystems. This will be addressed through answering these 4 core questions: 1. Where, by how much and why Canadian lakes have changed during the last centuries? 2. How do taxonomic, molecular and biochemical features of planktonic, benthic and microbial communities change with lake alteration and which ones can...


The effect of permafrost slumping on carbon delivery from land to water
Principal Investigator: Tank, Suzanne E
Licensed Year(s): 2019 2018 2017 2016 2015 2014
Summary: The objective of this study is to understand how permafrost slumping increases the mobilization of carbon from land to water, and the effects of this transport on stream ecosystems and the global carbon cycle. This summer, the research team will measure streamwater chemistry at a series of sites draining from the Peel Plateau, near where they enter the Mackenzie Delta. At one site (Stony Creek), t...


Paleozoic rift history of western Laurentia as recorded in Yukon-NWT-Alaska
Principal Investigator: Cobbett, Rose
Licensed Year(s): 2019
Summary: The objective is to use geochemistry (composition of rocks) and geochronology (dating of rocks) to characterize volcanic rocks in order to better understand the environment that they were formed in and in turn learn about the tectonic history of western North America through Paleozoic time (~541 - 252 Million years). Results will be published in a series of Yukon Geological Survey publications, se...
