Summary: The objective of this project is to identify for closures sites with no unacceptable risks and to develop an action plan for additional work for any sites that cannot be closed. Twenty-two sites will be visited to collect soil, surface water (where available) and vegetation samples to determine levels of previously identified contaminants of concern. The work plan for each site involves soil, s...

Summary: The goal of this project is to determine arsenic toxicity in the environment through time by using trees and soils from the area surrounding the Giant Mine. This will be done using synchrotron techniques to determine the intensity of toxicity in each year since the contamination started. A 5.1 mm tree borer will be used to take 2 cores from trees within a close proximity to Giant Mine. The res...

Summary: This research has two main objectives: 1) to monitor the spatial variability of soil moisture at the scale of a Soil Moisture Active Passive (SMAP) 36km pixel centered around the Trail Valley Creek (TVC) watershed; and, 2) to evaluate the current soil moisture algorithms and products currently utilized by SMAP. To achieve the first objective, the research team will install soil moisture monit...

Principal Investigator: Jakiela, Kevin
Licensed Year(s): 2016
Summary: The objective is to perform soil analysis (for composition) and researching parameters in Geodome on the Northern Farm Training Institute (NFTI) farm such as: air temp, relative humidity, light intensity, albedo, soil moisture/saturation and temperature. This analysis will help NFTI to figure out optimal growing conditions inside the greenhouse to optimize crop growth and yields. The research team...

Summary: The objective of this project is to continue an ongoing long-term monitoring of permafrost temperatures on Banks Island and Mould Bay. At these sites the research team have lost remote (satellite) communication and need to make repairs to continue receiving data. The research team are currently monitoring active layer and permafrost temperatures, active layer soil moisture, air temperature, and...

Principal Investigator: Miller, Clare B
Licensed Year(s): 2016
Summary: The objective of this research is to develop a greater understanding of the natural impacts of climate change on the loading, speciation and mobility of elements of concern in the subsurface in order to establish natural background concentrations for metal(loids) in pre-developed northern environments. In a region influenced by both accelerated climate change and wide- spread resource development,...

Principal Investigator: Phillips, Marcus R
Licensed Year(s): 2015 2014 2013
Summary: The goal of this research is to understand how landscape processes influence the quantity and quality of soil carbon in the Mackenzie Delta Region. Particular attention will be paid to the depth distribution of soil carbon and how it is affected by differences in vegetation and soil forming processes. Key environmental differences that will be examined include forest vs. tundra and delta vs. uplan...

Principal Investigator: Baird, Donald J
Licensed Year(s): 2014 2013
Summary: This project will assess the biodiversity in the Slave and Dog Rivers, NWT, using a variety of collection methods, to support the establishment of baseline biomonitoring conditions, and to explore the use of DNA-based identification of animals, plants and microorganisms. The food webs of these systems will also be described using stable isotope techniques. The project will contribute to the wider ...

Principal Investigator: Williams, Mathew
Licensed Year(s): 2014 2013 2012
Summary: The aim of the proposed project is to develop, parameterize and evaluate a detailed process-based model of vegetation soil- permafrost interactions using data collected through directed field campaigns in the discontinuous and sporadic permafrost zones of western Canada. The research team will (i) elucidate the role of plant biodiversity in controlling permafrost status in contrasting ecosystems w...

Principal Investigator: Wookey, Philip A
Licensed Year(s): 2014 2013
Summary: This research aims to understand what factors affect 1) the amount of carbon stored in tundra soils, and 2) the conversion of this soil carbon into greenhouse gases (carbon dioxide and methane). In particular, the research team wants to understand how hydrology (which is the distribution and movement of water in soils and streams) might affect the carbon cycle under future global warming. This inc...
