Principal Investigator: Douglas, Marianne
Licensed 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...

Principal Investigator: Lamoureux, Scott F
Licensed 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...

Principal Investigator: Rouse, Wayne R
Licensed 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...

Principal Investigator: Jalkotzy, Peter
Licensed Year(s): 2001 2000
Summary: The research team will conduct a lake and fish habitat survey, to identify which water bodies have the following characteristics: overwintering fish, lake depths greater than 3.5 feet and water quality conditions which are not suitable for overwintering fish. The research team will consist of 3 crews, 4 men/crew. Crews will receive their safety and sampling orientation in Tuktoyaktuk Harbour at ...

Principal Investigator: English, Michael C
Licensed Year(s): 2003 2002 2001 2000
Summary: Tthe objective of this study is to continue research examining the hydrological and energy budget of small arctic esker lake basin during the spring melt period. The intent of this research is to understand the relationship between the energy budget and changes in soil moisture, rates of evapotranspiration, and changes in water discharge from a small tundra basin underlain by permafrost. Transpo...

Principal Investigator: Hebert, Paul
Licensed Year(s): 1997
Summary: Our research will involve the survey of zooplankton communities in lakes and ponds of the Mackenzie Delta area (Inuvialuit private lands). Samples will be collected by either wading in ponds or by towing at net behind a float equipped helicopter. Samples will be frozen in liquid nitrogen, and subsequently examined for genetic variation. Our work aims to establish the species diversity of zoopla...

Principal Investigator: Carolsfeld, Joachim
Licensed Year(s): 1996
Summary: The researchers propose to collect invertebrates, algae and microorganisms with the use of SCUBA, plankton nets, bottom dredges, and intertidal collection. These samples will be sorted and frozen for later analysis in Halifax. The researchers wish to collect samples in about 25 sites, ranging from the southern tip of Liverpool Bay to south of Saunatuk. All collections will take place from small...

Principal Investigator: Perin, Sofia
Licensed Year(s): 1994
Summary: This study will be done by setting up 6 enclosures in a lake or pond. Two enclosures will be exposed to reduced UV-B levels, two other enclosures will be exposed to ambient UV-B levels, and finally two other enclosures will be exposed to enhanced UV-B levels. Regular measurements will be made of algae and invertebrates biomass, species composition, and pigment; and of algal photosynthesis and end ...

Principal Investigator: Howard, Susan
Licensed Year(s): 1993 1992
Summary: Ozone depletion in the High Arctic could result in exposure of aquatic organisms (such as bacteria) to higher levels of ultraviolet (UV) radiation from the sun. This increased exposure to radiation may be harmful to bacteria and have an effect on organisms which feed on bacteria. I will collect water samples from lakes and ponds in the Resolute area in order to measure bacterial growth rates as ...

Principal Investigator: Robilliard, L.J.
Licensed Year(s): 1992
Summary: In 1991, lake, pond and inlet water at Truelove Lowland, Devon Island was sampled to provide a limnologic description of this particular High Arctic setting. The objective is to group the lakes on the basis of various chemical and physical properties. The project will continue in 1992....
