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...


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...


The Arctic Great Rivers Observatory III
Principal Investigator: Holmes, Robert Max
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010 2009
Summary: The Arctic Great Rivers Observatory project studies the six largest rivers in the Arctic: the Mackenzie and Yukon Rivers in North America, and the Ob', Yenisey, Lena, and Kolyma Rivers in Russia. The research team are interested in how climate change is impacting Arctic rivers. The team will take measurements of the concentration of naturally-occurring chemicals (like carbon and nitrogen) and try ...


The effect of permafrost slumping on carbon delivery from land to water
Principal Investigator: Tank, Suzanne E
Licenced Year(s): 2017 2016 2015 2014
Summary: The objective of this study is to understand how permafrost slumping increases the mobilization of organic and inorganic carbon from land to water, and the effects of this movement on stream communities. To do this work, the research team will measure streamwater chemistry upstream and downstream of slump sites. The team will also examine the fate of this carbon by undertaking incubation experimen...


Tracing the Origin of Mercury Contamination in the Lakes and Fish of the Jean Marie River First Nation Lands
Principal Investigator: Laurent, Cyrielle C
Licenced Year(s): 2015
Summary: The short term objectives for this project are to: - Assess permafrost as a possible origin of mercury contamination; - Measure mercury content in permafrost samples; - Engage the community to exchange traditional and scientific knowledge to better understand relationships between country food, water quality, and permafrost degradation from a contamination perspective; and - Use traditional la...


Beaufort Sea Coastal Geoscience Research 2013
Principal Investigator: Whalen, Dustin JR
Licenced Year(s): 2016 2015 2014 2013 2012
Summary: The primary objective of this research is to ensure safe and sustainable industrial and community development by improving the understanding of coastal and nearshore seabed processes and properties. The research provides the means to improve the knowledge of physical conditions in the coastal zone in order to help government agencies, corporations, and local residents understand, mitigate and redu...


Permafrost regions in transition: controls on carbon cycling and greenhouse gas emissions
Principal Investigator: Wookey, Philip A
Licenced Year(s): 2014 2013
Summary: This research aims to understand what factors affect 1) the amount of carbon stored in tundra soils, and 2) the conversion of this soil carbon into greenhouse gases (carbon dioxide and methane). In particular, the research team wants to understand how hydrology (which is the distribution and movement of water in soils and streams) might affect the carbon cycle under future global warming. This inc...


Composition of natural dissolved organic carbon in streams along latitudinal transect
Principal Investigator: Turetsky, Merritt R.
Licenced Year(s): 2011
Summary: The goal of this research project is to measure the concentration and composition of natural dissolved organic carbon in rivers along a latitudinal transect from central Alberta to southern NWT. Data on water quality will be combined with spatial data that describes the drainage basins of the sampled rivers, e.g. ecosystem composition, size, slope, recent fire impact and permafrost conditions. The...


Hydro-ecological Responses of Arctic Tundra Lakes to Climate Change and Landscape Perturbation
Principal Investigator: Wrona, Frederick J
Licenced Year(s): 2011 2010 2009
Summary: The overall objective of this study is to develop a model that can be used to look at the vulnerability of small arctic lakes and ponds to changing climate. Lake Ice Study: Lakes 5A, 5B and Noell Lake (MAP-2 of the original licence application) will be visited in mid-April to measure lake ice. Holes will be made in the ice using an ice corer. Ice thickness and composition will be determined by...


Geological conditions affecting industrial and community development in the coastal and nearshore regions of the western Canadian Arctic - year 4/4
Principal Investigator: Solomon, Steven M
Licenced Year(s): 2010 2009 2008 2007
Summary: The western Arctic coast is among the most rapidly changing coastlines in the world and one of the most sensitive to climate change. The objective is to improve knowledge of physical conditions in the coastal zone in order to help government agencies, corporations, and local residents understand, mitigate and reduce the impacts of natural changes and industrial or community development. Spring...
