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...

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...

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...

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 ...

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...

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...

Summary:
In accordance with the Mackenzie Valley Land and Water Board (MVWLB) Guidelines, the overarching closure goal for former mine sites is to return the site and affected areas to viable, and wherever practicable, self-sustaining ecosystems that are compatible with a healthy environment and with human activities. To meet this closure goal, companies must demonstrate that a site is physically stable, c...

Summary:
The aim of this project is to combine remote sensing data, field measurements and biogeochemical modeling to improve methane emissions estimates from thawing permafrost peatland landscapes at local, regional and global scales. To accomplish this, the research team will integrate data on water table and vegetation from remote sensing (satellites, unmanned aerial vehicle (UAVs)), with local measurem...

Summary:
The main goal of this project are to establish a stream biomonitoring program along the Dempster–Inuvik–Tuktoyaktuk-Corridor (DITC) to understand the current environmental conditions associated with past and newly developed road infrastructure.
Specific objectives are:
1) to establish a stream biomonitoring program for the Inuvik – Tuktoyaktuk Highway (ITH);
2) to directly involve local stak...

Summary:
The objective of the fieldwork is to collect soil samples from the active layer and near-surface permafrost. Twelve samples will be collected from coastal bluffs at Crumbling Point, and six samples from river banks beside East Channel.
Soil profiles 1-2 m deep and naturally exposed by coastal, lake or river erosion will be cleared of slumped soil by spade, and described and recorded. At each si...
