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 ...


Impacts of permafrost thaw on hydrology and water resources
Principal Investigator: Quinton, William L.
Licenced Year(s): 2017
Summary: Understanding the ecology and hydrology of ecosystems with thawing permafrost is a major challenge. To meet this, the research team will develop new knowledge on the eco-hydrology of the major ecosystems (i.e. bogs, fens, peat plateaus) needed to develop new science-based tools to predict the future supply for the next 50 years. The specific scientific objectives are to: 1) develop fundamental kno...


Beaufort Marine Hazards / Integrated Beaufort Observatory
Principal Investigator: Melling, Humfrey
Licenced Year(s): 2017 2016
Summary: The strategic objective of this expedition is continued long-term monitoring of Canadian Beaufort Sea. The specific objectives are: 1) to recover, service and re-deploy oceanographic moorings carrying instruments that measure ice thickness and ridging, storm waves, sea level, ocean current, temperature and salinity, mammal vocalization, underwater sound and plankton; and, 2)to complete oceanogr...


Taltson Hydroelectric Facility Aquatic Monitoring
Principal Investigator: Miller, Matthew
Licenced Year(s): 2017 2016
Summary: The objective of the monitoring and mitigation is to determine operating procedures and mitigation options for the annual shutdown at Taltson Hydroelectric Facility to minimize the environmental impact on downstream Trudel Creek. Various mitigation options have been and are being assessed and the results on Trudel Creek are being monitoring to determine the best operating procedure for the ann...
