Permafrost and climate change, western Arctic Canada
Principal Investigator: Burn, Chris R
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998
Summary: The objective of this research is to understand the rate of ground warming in permafrost due to climate change and to measure the changes in ground surface characteristics that are occurring as a result. In particular, the research team are interested in changes in ground temperature, in the depth of the active layer, and in subsidence of the ground. The research team are also interested in measur...

Beaufort Sea Coastal and Nearshore Geoscience Research 2017
Principal Investigator: Whalen, Dustin JR
Licenced Year(s): 2017
Summary: The objective of this project is to provide the means to improve the knowledge of physical conditions in the Arctic coastal zone in order to help government agencies, corporations and local residents understand mitigate and reduce the impacts of climate driven changes. Field surveys will be undertaken in consultation with Hunters and Trappers Committees (HTCs) in order to ensure the timing of ...

Polar Airborne Measurements and Arctic Regional Climate Model Simulation Project (PAMARCMIP)
Principal Investigator: Herber, Andreas
Licenced Year(s): 2017
Summary: The observational platform will be a single aircraft, the Alfred Wegener Institute (AWI) POLAR 5, a modified DC-3 aircraft. Objectives of this project are to: 1. determine the actual state of the sea ice thickness distribution in the western Arctic and what are trends of the Sea Ice thinning; 2. characterize the actual sea ice thickness distribution and identify trends in the sea ice thickne...

Biogeochemistry of Lakes in the Mackenzie Delta
Principal Investigator: Lesack, Lance
Licenced Year(s): 2017 2016 2015 2014 2010 2009 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993
Summary: The objective of this research project are to: 1) improve the understanding of microbial carbon-processing in Mackenzie Delta lakes and how it is affected by the changing water levels; and, 2) to decipher the impact of water level changes on the ability of the Mackenzie Delta to affect riverine nutrient flow to the ocean. This work will help resolve what drives microbial communities in Mackenzi...

Studies of methane release from lakes in the Mackenzie Delta and on Richards Island
Principal Investigator: Orcutt, Beth N
Licenced Year(s): 2017 2016 2015
Summary: The focus of this one-year-long project is to collect an additional annual record of methane release from nine different lakes in the Mackenzie Delta and Richards Island area, with a focus on capturing a full ice in/ice out cycle, to determine how much methane is released from lakes under different conditions and how microorganisms increase or decrease methane release. This annual record will allo...

Establishing a watershed framework for assessing cumulative impacts of development
Principal Investigator: Chin, Krista
Licenced Year(s): 2017 2016 2015 2014 2013
Summary: Objective 1: Build a partnership between government, communities, regulators and researchers to develop a watershed-based cumulative impact study in areas of oil and gas exploration in the Sahtu region. The Sahtu Renewable Resource Board (SRRB) can play an important coordinating role in bringing partners together and working with the communities to determine appropriate engagement in the projec...

Effects of fire on peatland permafrost stability and carbon cycling
Principal Investigator: Olefeldt, David
Licenced Year(s): 2017 2016 2015
Summary: The project team intend to study carbon cycling in peatland catchments, in order to determine whether the interactions between wildfire and permafrost thaw causes increased release of greenhouse gases from peatlands and aquatic ecosystems to the atmosphere, and thus cause amplified climate change. Given the overall objective of the project, the team intend to address five research questions: ...

Mackenzie Mountains Aeromagnetic Survey
Principal Investigator: Coyle, Maurice
Licenced Year(s): 2017
Summary: The objective of this airborne survey is to acquire high-resolution aeromagnetic data. This survey will be flown to improve the knowledge of the area. It will support potential future ground-based geological mapping and to provide basic information to support mineral exploration. The survey will consist of approximately 77,000 line km of surveying flown at a line spacing of 800 m (or 2625 feet)...

Permafrost in the western Arctic
Principal Investigator: Kokelj, Steve V
Licenced Year(s): 2017 2016
Summary: The primary objectives of this research are: 1) to develop and test new methods of monitoring permafrost landscape change; 2) to investigate the impacts of natural and human disturbance on permafrost terrain and the ground temperature conditions in natural environments and in communities; and, 3) to assess the physical and chemical characteristics of permafrost. To achieve the objectives the r...

Community-Based Water Quality Monitoring in the Northwest Territories
Principal Investigator: Beveridge, Meghan
Licenced Year(s): 2017 2016 2015 2014 2013
Summary: The purpose of the project is to work in collaboration with Northwest Territories (NWT) communities to collect water quality data to answer community concerns and questions about the health of NWT waters, to enhance understanding of cumulative impacts and to contribute to decision making. There are three associated objectives: 1) collect water quality data at locations throughout the NWT, to ...
