Landscape Change on Banks Island.
Principal Investigator: Lantz, Trevor C.
Licenced Year(s): 2016 2015
Summary: The objectives of this research project are: 1) To use remote sensing to document the rate and extent of landscape change on Banks Island; 2) To examine the effects of tundra disturbances using detailed field investigations; and 3) Use participatory mapping and interviews to document Inuvialuit Knowledge of Landscape Change on Banks Island. In this project the research team are using remot...


Thermal State of Permafrost
Principal Investigator: Siegfried, Dian
Licenced Year(s): 2016 2013 2010
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...


Impacts and remediation of wetland vegetation affected by development in Northern Areas
Principal Investigator: Stevens, Kevin J
Licenced Year(s): 2015
Summary: The overall goals are to 1) quantify the effects of mining and development on northern wetland vegetation through the application of historic vegetation ecology practices and the development of novel approaches to quantify and monitor the effects of mining and other development related disturbances on wetland vegetation; 2) improve methods for assessing the success of wetland restoration/remediati...


Organic carbon accumulation under Picea sp. (Picea glauca, P. mariana) stands along its range northern boundary
Principal Investigator: Pichler, Viliam
Licenced Year(s): 2015
Summary: The objective of this study is to determine soil organic carbon quantity and quality under open stands of Picea glauca and Picea mariana close to northern forest limits as opposed to open tundra. To enable predictions of forest propagation on soil carbon dynamics under extreme climate conditions. Taking samples from the soil and trees in the Richardson Mts., specifically at two points with the...


Gordon Lake Assessment Project
Principal Investigator: Doucet, Michael
Licenced Year(s): 2016 2015
Summary: The objective of this program is to determine the environmental and physical conditions at nine sites on Gordon Lake and potentially six Gordon Lake south sites. This will include the identification and quantification of environmental impacts in soil, sediment, surface water and groundwater, and the identification of any hazardous or non-hazardous materials. In addition, samples of biota (includin...


ARCTICFIRE
Principal Investigator: Pumpanen, Jukka S
Licenced Year(s): 2015
Summary: The aim of the ARCTICFIRE project is to study the long term effects of natural forest fires on the decomposition of soil organic matter in the northern arctic and subarctic forests. The research team will study the changes in size and quality of soil carbon and nitrogen pools and fluxes after forest fires and their underlying processes in the arctic and subarctic zone, especially the interactions ...


South Rae Project
Principal Investigator: Pehrsson, Sally J
Licenced Year(s): 2016 2015 2014 2012
Summary: This work is part of NRCan’s Geo-mapping for Energy and Minerals Program, designed to upgrade the geoscience knowledge base in Canada’s North to modern standards. A team of 10-15 scientists set up a temporary camp in the area of interest. Float planes, helicopter and boats are used to access remote areas. The scientists walk on the land and make observations, take notes and draw sketches. Small...


Ground ice - vegetation relationships in the North Slave region
Principal Investigator: Baltzer, Jennifer L
Licenced Year(s): 2015 2014
Summary: The primary objective is to quantify the relationships between vegetation community composition, structure and near-surface ground ice content. An improved understanding of ground ice-vegetation interactions allows a better understanding of permafrost ecosystems the ability to more easily measure near surface ground ice conditions. Around Yellowknife there is a patchwork of bedrock outcrops sep...


Biogeochemical variations in Pleistocene and Holocene-age permafrost across various ecological landscapes, western Canadian Arctic.
Principal Investigator: Lacelle, Denis
Licenced Year(s): 2014
Summary: The proposed project is a collaborative work between academic researchers, the NWT Geoscience Office and local communities. The objectives of the project are to: (1) investigate geochemical variations in the uppermost 3-5m of permafrost in the western Canadian Arctic; (2) assess potential geochemical implications of anticipated permafrost thaw on terrestrial and aquatic systems; (3) examine soil c...


Great Bear RIver Summer of 2012 Site Assessments
Principal Investigator: Geddes, Robert B
Licenced Year(s): 2012 2011
Summary: The assessment is designed to delineate the horizontal and vertical extent of uranium contaminated soil at sites located along the Great Bear River portion of the Northwest Transportation Route (NTR). The soil quality and quantity information gathered during this assessment is required to assist in the development of future remediation plans for this segment of the NTR. The proposed tasks are a...
