Airborne Observations in Support of NETCARE
Principal Investigator: Abbatt, Jon
Licenced Year(s): 2015
Summary: The NETCARE observations will be covered the range from Longyearbyen, Svalbard (European Arctic) until Inuvik (NWT – Polar 6 aircraft only) and Barrow (Alaska – Polar 5 aircraft only). The observational platforms will be two aircraft: 1) the Alfred Wegener Institute (AWI) POLAR 5, a modified DC-3 aircraft; and 2) the AWI POLAR 6, also a modified DC-3 aircraft. The two platforms will be coordin...

Aerosol Chemical Composition in the Arctic (ACCA), a subproject to RACEPAC
Principal Investigator: Borrmann, Stephan P
Licenced Year(s): 2014
Summary: The objectives of this research project are: (1.) To perform in-situ measurements of number concentrations, optical properties, and chemical composition of atmospheric aerosol particles with sizes between 3 nanometers and 10 micrometers. (2.) Identify aerosols of natural and anthropogenic origin. (3.) Quantify their relative contributions in dependency of particle size. (4.) Evaluate the pot...

Social and political perceptions of environmental resources extraction projects in the Sahtu Settlement Area
Principal Investigator: Perombelon, Brice B.P
Licenced Year(s): 2013
Summary: The principal researcher wishes to study the environmental impacts of resources extraction projects (present and future) on the community members. The hope is to do this through a survey of their perceptions of environmental problems caused by resources extraction projects (gas & oil) and see whether they think that these projects will create more problems of environmental degradation (for example...

Supplemental Environmental Site Assessments along the Canol Trail, NT
Principal Investigator: Livingstone, Steve
Licenced Year(s): 2013 2012 2010
Summary: The purpose of the Supplemental Environmental Site Assessments is to further determine the current environmental and physical conditions at several petroleum hydrocarbon spill sites along the Canol Trail, and address the gaps identified from the 2012 sampling program. Key findings from these select sites will be synthesized to identify the scope and nature of the spills, potential trends regarding...

Mass Balance of Arctic Glaciers and Arctic Pollution
Principal Investigator: Koerner, Roy M
Licenced Year(s): 2008 2007 2006 2005 2004 2003
Summary: The objectives of this ongoing research project are: (a) to monitor climate change by measuring the changing volume of the ice cap and maintaining an automatic weather station, and (b) to monitor air and snow pollution by sampling snow and sending it to be analyzed. Based out of the Polar Continental Shelf Project in Resolute Bay, NU, two personnel will fly by Twin Otter to the ice cap, and liv...

Lithogenic elements and isotopes in peat cores as markers of Holocene climate changes in the Mackenzie River valley
Principal Investigator: Outridge, Peter M
Licenced Year(s): 2007
Summary: The objective of this research is to reconstruct climate change information as well as recent industrial mercury and lead pollution histories for Inuvik and the lower Mackenzie River valley. To determine the above, a core sample of peat will be taken from a peat bog located near Inuvik, and analyzed for elements and dusts deposited from the air over the last 7,000 years. The site will be a...

Increasing Boreal Forest Fire: Future Impacts on Arctic Environment and Climate
Principal Investigator: Stocks, Brian J
Licenced Year(s): 2007
Summary: The research aims to characterize the physical and chemical properties of forest fire smoke and its impact on the Artic. Three aircraft (CT-133 jet, Dehavilland Sea Heron and Dehavilland Twin Otter) based out of Yellowknife, equipped with standard scientific atmospheric chemistry sampling instrumentation, will be used to sample smoke while airborne. Sampling will take place opportunistically as fi...

Biological studies of waters along the proposed Mackenzie Gas Pipeline route - Inuvialuit Settlement Region
Principal Investigator: Evans, Marlene
Licenced Year(s): 2009 2008 2007 2006
Summary: This study is designed to fill gaps in Environment Canada’s understanding of the aquatic environment potentially impacted by various aspects of the Mackenzie Gas Project (MGP). Potential stressors including: increased erosion, nutrient releases from sewage discharges, other chemical releases, water withdrawals, impacts of barge traffic, increased atmospheric emissions, etc. The focus will be on th...

Human and chemical ecology of arctic pathways taken by marine pollutants
Principal Investigator: Kassam, Karim-Aly S.
Licenced Year(s): 1999
Summary: Research will begin with the development of a database of existing information concerning impact of pollutants on the human ecology. An interview protocol will be developed for collecting indigenous knowledge on the impact of chemical pollutants. By training two researchers in each community surveyed, local indigenous knowledge will be collected through participation by community based staff. All ...

Tundra Northwest 1999
Principal Investigator: Karlqvist, Anders
Licenced Year(s): 1999
Summary: The overall goal of the expedition Tundra Northwest 1999 is to study geographic variation of terrestrial and freshwater ecosystems of the tundra. By using the CCG icebreaker Louis St. Laurent for transport and as a scientific platform the the expedition route will include a longitudinal gradient from Baffin Island to the northern coast of Alaska and a latitudinal gradient through the Canadian Arc...
