Tuktoyaktuk Lake and Fish Habitat Survey
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 ...


Genetic Diversity in the Biota of Arctic Lakes
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...


Chemical Investigation of Marine Invertebrates from Husky Lakes
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...


The Effects of UV-B Radiation On the Community of Arctic Lakes
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 ...


The effect of UV light on bacterial growth rates in lakes and ponds in the Canadian High Arctic
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 ...
