Principal Investigator: Singer, Claire L
Licensed Year(s): 2022 2021
Summary: This licence has been issued for the scientific research application No.5272. The proposed research aims to measure the extent of non-native plant spread into natural areas in the NWT, assess the impact of this spread to native plant and soil communities, and assess the risk of invasion from plants in neighbouring jurisdictions. Sampling plots at increasing distances from the roadside or ri...

Summary: This licence has been issued for the scientific research application No.4994. The goal of this project is to document existing environmental conditions surrounding the Project area. Studies may include the following. Hydrology studies include the measurement of selected lake inflow and outflow and stream profile through field surveys, and installation of data loggers to continually monitor l...

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: Reimer, Kenneth J.
Licensed Year(s): 2012
Summary: The objectives of this research is to: determine total arsenic and arsenic species in edible and non-edible mushrooms from contaminated and uncontaminated locations (mine properties and roadsides/parks); determine total arsenic and arsenic species in plants including Labrador tea, horsetails, buffaloberry, fireweed and berries (if available) from contaminated and uncontaminated locations (mine pro...

Principal Investigator: Langhorne, Amy
Licensed Year(s): 2011
Summary: The objective of the plant and soil sampling is to determine baseline metal and polycyclic aromatic hydrocarbon concentration in surficial soils and plants growing in the study area. The data will be used in the human health and terrestrial wildlife risk assessment. The proposed study will include the collection of up to 30 co-located soil, plant, and insect samples at six terrestrial locations...

Principal Investigator: Bromstad, Mackenzie J
Licensed Year(s): 2010
Summary: The objective of this project is to understand why arsenic trioxide (As3+) is still present in soils around Giant Mine, how long it will remain there, and if the set of circumstances leading to persistent As3+-rich soil may apply to any other places previously assumed to be As3+-free. In terms of current mine remediation, future human contact with the site, and ecosystem health, it needs to be und...

Principal Investigator: Farrell, Rory
Licensed Year(s): 2009
Summary: The objectives of this project are to characterize and delineate potential contaminants of concern at the Site, determine volumes of Hazardous Materials at the Site and identify potential borrow sources for landfilling at the Site (if necessary). A remedial action plan will then be developed outlining the most environmental, and cost effective method to restore the Site to its natural condition. ...

Principal Investigator: Lennie-Misgeld, Peter
Licensed Year(s): 2009 2008
Summary: Soil samples will be taken from representative sites in order to complete soil reclamation suitability assessment. Surficial sediments and soils will be described at each pit. In addition, notes will be taken on vegetation, drainage and terrain features, etc. A permafrost survey will consist of drilling shallow holes (<3 m) to determine permafrost conditions. Shallow permafrost drilling will be...

Principal Investigator: Coxson, Darwyn S
Licensed Year(s): 2008 2007
Summary: The objective of this research is to study how northern soils in close proximity (geospatially linked soils) cycle nitrogen and carbon and produce greenhouse gases. Describing these links will allow forecasting on how the soils respond to climate change. Three transects with 31 sampling locations will be set up. At each location a Time Domain Reflectometry (TDR) probe and thermocouple will be i...

Principal Investigator: Wiatzka, Gerd M
Licensed Year(s): 2007 2006
Summary: Indian and Northern Affairs Canada (INAC) has assumed responsibility for the contaminated sites of the Indore and Beaverlodge (Hottah) Mines and is in the process of characterizing the ecological and human health and safety risks associated with the sites in order for remediation strategies to be developed. The work involves manual sampling and measurement with minimal disturbance of site cond...
