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): 2018 2017 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...

Environmental soil chemistry at abandoned drilling mud-sumps in the Kendall Island Bird Sanctuary, Mackenzie Delta Region
Principal Investigator: Biggar, Kevin
Licenced Year(s): 2006 2005
Summary: Since the 1970's, the oil and gas industry has drilled at least 19 exploratory wells in the Kendall Island Bird Sanctuary (KIBS), but there is a shortage of field data describing environmental conditions at the well-sites and drilling-mud sumps. In Marc...

ChevronTexaco 2005 Drilling Operations - Project Description Data Collection
Principal Investigator: Pyc, Cynthia
Licenced Year(s): 2004
Summary: Soil samples will be taken from four potential sump sites for the 2005 drilling program. Soil samples will provide information on active layer depth, soil composite, salinity levels, permeability and moisture content to determine sump site suitability. I...

Monitoring Program for the Misery Site Surplus Water Atomization Project
Principal Investigator: Armstrong, Allison
Licenced Year(s): 2003
Summary: The Mackenzie Valley Land and Water Board has authorized the discharge of a small amount of water through an experimental water treatment system. This system sprays water into the air and onto the tundra. It is anticipated that the water that is discha...

Delineation of Komokuk Beach (BAR-1), and Nicholson Peninsula (BAR-4).
Principal Investigator: Reimer, Kenneth J.
Licenced Year(s): 1997
Summary: The Environmental Services Group has been requested by Defence Construction Canada and DCLU, to continue conducting environmental investigations of former DEW Line sites. Personnel will collect soil, sediment, plant, water, paintchips and insulation samples from areas of suspected or known contamination. The samples will be analyzed for inorganic elements and PCB's. In addition a small-scale bio...

Licence #5066
Principal Investigator: Kelly, Peter
Licenced Year(s): 1985
Summary: To examine the physical, chemical, and mineralogical characteristics of the soils formed on the beaches as a function of environmental change....

Licence #2802
Principal Investigator: Brozowski, Jim
Licenced Year(s): 1982
Summary: To undertake a geomorphological survey of the soils, including physical and chemical characteristics....
