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...


Nutrient Availability in Arctic Tundra Soils
Principal Investigator: English, Michael C
Licenced Year(s): 2008
Summary: This licence is issued for the scientific research application # 876. The objective of this research is to determine the impacts of predicted soil warming scenarios for the arctic on the availability of phosphate, nitrate-nitrogen and ammonium, which are important soil nutrients. The field portion of this research will consist of two weeks of collecting soil data and gauging and sampling (f...


Recent changes in carbon source-sink relationships and greenhouse gas emissions in forest and peatland ecosystems along the Mackenzie Valley region of Canada
Principal Investigator: Bhatti, Jagtar
Licenced Year(s): 2011 2010 2009 2008 2007
Summary: The objective of this research is to assess variations and processes controlling CO2, CH4 and N2O dynamics along the Mackenzie Valley, to investigate the amount and character of greenhouse gases released, and to understand conditions controlling soil GHG emissions. Soil gas sample tubes will be sampled on a seasonal basis for gas concentration (CH4, N2O, CO2) and isotope ratios. The response of...


A Global Reconnaissance Survey of Perfluorinated Compounds in Soils
Principal Investigator: Washington, John
Licenced Year(s): 2006
Summary: PFOA is a synthetic compound documented as being widely dispersed in the environment, including in biota of high-northern latitudes. The route of this dispersal is not entirely clear. PFOA concentrations in soil samples from several locations around the world will be analyzed to determine environmental reservoirs and global distribution. Two new 250-ml HDPE sample bottles will be shipped to Auro...


Canadian Tundra Climate Exchange Project
Principal Investigator: Lafleur, Peter M
Licenced Year(s): 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2007 2005 2004
Summary: The purpose of this study is to examine carbon exchange between the arctic tundra and the atmosphere. Specifically, the researchers are interested in variation in carbon exchange in response to environmental factors such as soil moisture and weather (tem...
