Principal Investigator:Tonn, William Licenced Year(s):
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 ...
Principal Investigator:Wrona, Frederick J Licenced Year(s):
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...

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...

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 ...
Principal Investigator:Prowse, Terry D Licenced Year(s):
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...
Principal Investigator:Gajewski, Konrad Licenced Year(s):
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...
Principal Investigator:Tomkins, Jessica Licenced Year(s):2006
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...
Principal Investigator:Douglas, Marianne Licenced Year(s):
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...
Principal Investigator:Lamoureux, Scott F Licenced Year(s):
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...
Principal Investigator:Rouse, Wayne R Licenced Year(s):
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...
