Improving Habitat Connectivity to Enhance Productive Capacity of Arctic Freshwater Ecosystems
Principal Investigator: Tonn, William
Licenced Year(s): 2014 2013 2012 2011 2010 2009
Summary: The objectives of this research project are: to study the freshwater ecology, hydrology, and hydraulics of small lakes and streams in the Lac de Gras basin before habitat modification; to monitor the changes in ecosystem productive capacity resulting from habitat modifications designed to increase habitat connectivity and fish passage; and to assess the effectiveness of such habitat modifications ...


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...


Noell Lake Ice Study - 2nd Amendment to 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 component is to improve 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. All other research activities related to this work have been reviewed/approved/fully-licensed as part the overall research project “Hydro-ecological Responses of Arct...


Amendment - 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 research component is to improve the knowledge on present-day food webs/productivity in small Arctic pond/lake systems, in order to better predict changes that could occur under changing climate. The methodology described below pertains to all new research activities related to this new research component dealing with fish. All other research activities related to ...


Sensitivities of high-latitude lakes to climatic & development disturbances
Principal Investigator: Prowse, Terry D
Licenced Year(s): 2008 2007 2006 2005
Summary: The objective of this study is to develop a hydro-ecological model for small Arctic lakes to assess the vulnerability of their ecosystems to disturbances, such as climate change or water withdrawal. To quantify geochemical loadings to lakes, a model is being developed by monitoring lakes and their contributing catchment (surface water flow). A climate station will be set up at 2 - 6 sites to mo...


Postglacial Paleoclimatology of the central and western Arctic Islands
Principal Investigator: Gajewski, Konrad
Licenced Year(s): 2008 2004 2001 1994 1993 1992 1991 1990
Summary: The goal of this study is to collect lake sediment cores from shallow lakes to quantify the impact of past climate change on the vegetation and lakes of the area. Sediment cores from the bottom of 2 lakes in the region will be collected. A 10 day camp of 3 people will be set up at 71°43'12"N, 122°02'31"W. Transportation will be by Twin Otter to the camp, and by walking to the lakes. No gas powe...


Climate forcing factors and the record of climatic variability in the western Canadian Arctic during the past 2000 years
Principal Investigator: Tomkins, Jessica
Licenced Year(s): 2006 2005
Summary: The idea of the study is that researchers use the layers of sediment in a lake-bottom to figure out what the climate was like every year from last year to 2000 years ago. The researchers want to 1) look at cores of lake-bottom sediment that show layers...


Water Quality Assessment and Climate History of Selected Ponds and Streams on Melville Island
Principal Investigator: Douglas, Marianne
Licenced Year(s): 2002 2000 1999
Summary: The overall goal of the research is to more fully understand the present-day water quality of arctic lakes and ponds, and to attempt to determine if the water quality of these sites are changing as a result of, for example, recent climatic change or othe...


Late Quaternary History of the Richardson Mountains and the Melville Hills
Principal Investigator: Lamoureux, Scott F
Licenced Year(s): 2001
Summary: The research will require fieldwork in the Richardson Mountains between 27 April and 8 May, 2001. Research will involve the development of a high-resolution paleoenvironmental record based on lake sediments from up to six lakes in the Richardson Mountains and the Melville Hills in the NWT. Transportation in the field for the Dempster Highway study will be by snowmobile and snowshoes. If snow cov...


Modelling the energy and water balance and characteristics of lakes in the Mackenzie River Basin.
Principal Investigator: Rouse, Wayne R
Licenced Year(s): 2001
Summary: The field work associated with the proposed study will consist of the collection of climate data, such as air temperature, humidity, wind speed, wind direction, amount of rain fall, water temperatures and light penetration into the lake. Similar equipment will be used to collect this data at all sites. Air temperature, humidity, wind speed, wind direction, water temperatures and light penetration...
