Examining the impacts of climate and environmental change on aquatic and terrestrial ecosystems of the Mackenzie region, NWT
Principal Investigator: Pisaric, Michael FJ
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010 2009
Summary: This research will continue the long term objective of documenting and understanding the impacts of recent climate change on northern terrestrial and aquatic ecosystems. The short term objectives of this research are: 1) to investigate the impacts of permafrost degradation and subsequent thaw slumping on freshwater ecosystems; 2) to examine the limnological implications of drained lakes on aquatic...


Noell Lake Ice Study - Hydro-ecological Responses of Arctic Tundra Lakes to Climate Change and Landscape Perturbation
Principal Investigator: Wrona, Frederick J
Licenced Year(s): 2015 2014 2013 2012 2011 2010 2009
Summary: The overall objective of this research is to improve the knowledge on lake ice and its effect on food webs/productivity in small Arctic lake systems in order to better predict changes that could occur under changing climate. The research involves the automated ice buoy and instrumented subsurface mooring system for continuous monitoring of weather conditions, lake ice cover (formation, growth o...


The Arctic Great Rivers Observatory
Principal Investigator: Holmes, R. 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 is interested in how climate change is impacting Arctic rivers. The team will make measurements of the concentration of naturally-occurring chemicals (like carbon and nitrogen) and try to...


The Arctic in Flux: How has Recent Climate Change Affected Contaminant Transport and Uptake in Aquatic Arctic Systems?
Principal Investigator: Blais, Jules M
Licenced Year(s): 2013 2012
Summary: This research will determine how the recent and dramatic climate changes in Arctic freshwater have affected the transport and fate of anthropogenic contaminants to freshwater systems, two of the largest threats facing northern communities and ecosystems. This research will develop new tools to examine how the fate of anthropogenic contaminants is affected in Arctic regions under different climate ...


Deltaic Lake Sediments as Recorders of Past Carbon Export from Arctic River Drainage Basins
Principal Investigator: Vonk, Jorien
Licenced Year(s): 2011 2009 2007
Summary: The research project goal is to collect surface sediments, bank and levee sediments, particulate sediments and shallow sediment cores from lakes in the Mackenie River Delta, and to evaluate their utility as potential archives of information concerning past permafrost stability by assessing down-core changes in the age and supply of terrestrial carbon. In 2007 and 2009, teams led by Prof. Tim Eglin...


Towards Long-term Monitoring of the CO2 System in Arctic Rivers
Principal Investigator: Wang, Zhaohui 'Aleck'
Licenced Year(s): 2012 2011 2010
Summary: The goal of this research is to initiate time-series measurements of the CO2 system in the Mackenzie River, the major Arctic river in North America. This work will serve as the initial step towards long-term measurements and studies of the impacts of global warming on the CO2 systems in Mackenzie River, its estuary, and adjacent coastal waters. The field campaigns will include both diurnal and...


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...


Lake 5A Mesocosm Study - 3rd Amendment to Hydro-ecological Responses of Arctic Tundra Lakes to Climate Change and Landscape Perturbation
Principal Investigator: Wrona, Frederick J
Licenced Year(s): 2010
Summary: The overall objective of the Lake 5A mesocosm study is to better understand the impact of permafrost thaw shoreline slumping (an analogue for a warming climate) on the bottom components of the aquatic food-web in small Arctic tundra lakes in order to better predict the effects of a warming climate on food-web structure, function and productivity. To assess the direct and indirect effects of per...


Modelling Temperature and Heat Fluxes of Great Bear Lake
Principal Investigator: Schertzer, William M.
Licenced Year(s): 2009 2008
Summary: This licence is being issued for the scientific research application No.1100. The four main objectives of this research are: 1) to conduct observations on Great Bear Lake to measure meteorology, heat fluxes, and physical limnological components; 2) to model the thermal structure of Great Bear Lake under current climate and climate changed conditions; 3) to quantify the variability in the meteor...


Climate Change in the Central Northwest Territories - A Paleolimnological Analysis
Principal Investigator: Galloway, Jennifer
Licenced Year(s): 2009
Summary: This licence is issued for the scientific research application #932. The goal of this multi-disciplinary paleolimnological study will be employed to describe and further understand regional climate conditions, fire history, and ice cover duration spanning the past ~2000 years in the central Northwest Territories. The targeted study area is the southern portion of the Tibbitt to Contwoyto Winte...
