Do the Mosquitoes in the NWT have Wolbachia?
Principal Investigator: Hansen, Tamara A
Licensed Year(s): 2008
Summary: The objective of this research is to collect mosquitoes from the Inuvik area and perform a set of genetic tests to see if they are infected with a particular bacterium called Wolbachia. This bacterium is harmless to humans but affects the mating process of mosquitoes by killing the sperm of an infected male. A presence of Wolbachia has not been detected in the NWT as of yet, but if detected coul...

Monitoring Program for the Misery Site Surplus Water Atomization Project
Principal Investigator: Armstrong, Allison
Licensed Year(s): 2003
Summary: The Mackenzie Valley Land and Water Board has authorized the discharge of a small amount of water through an experimental water treatment system. This system sprays water into the air and onto the tundra. It is anticipated that the water that is discha...

Paleo-hydrology in the Arctic
Principal Investigator: CLARK, Ian D.
Licensed Year(s): 2000 1999
Summary: Data will be collected that can help to predict climate of the near future and determine the impact of temperature change on northern hydrology. The investigator will attempt to better understand how methane-producing bacteria function giving us a better understanding of their feedback on climate change. The research area is a quarry along the Dempster highway east of Campbell Lake. This site w...

Bacterial Biodiversity as a Source of New Biological Products.
Principal Investigator: Nano, Francis
Licensed Year(s): 1999
Summary: The goal of this project is to find new biological products of commercial and medical importance made by bacteria associated with permafrost soils, and to describe the bacterial biodiversity associated with the soils. A total of 500 small soil samples will be collected within 200 m. of the Dempster Highway (in undeveloped areas) between Dawson and Inuvik during August 1999. The decisions for the...

Precambrian reefs on Victoria Island
Principal Investigator: Narbonne, Guy
Licensed Year(s): 1996
Summary: Study 800 million year old fossil reefs near Wynniatt Bay on Victoria Island. Will fly to the site using Polar Shelf Twin-Otter aircraft. Measurements and pictures will be taken of the rocks and about 100 kg of rock samples will be collected with a hammer. The rock samples will be studied back at the university....

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 ...

Trophic dynamics of the microbial community in cold ocean environments
Principal Investigator: Rivkin, Richard
Licensed Year(s): 1993
Summary: The proposed research will examine the importance of marine algae and bacteria in the polar food web. This research is similar to previous studies I have conducted which examined food webs in the Atlantic Ocean (off of the coast of Newfoundland) and Antarctica. In Resolute, I will measure the production and growth of natural populations of algae and bacteria under different light, temperature and...

Fate of Sewage-Derived Contaminants in a Shallow Sand Aquifer, Fort Resolution, N.W.T.
Principal Investigator: McNaughton, Duane
Licensed Year(s): 1992
Summary: The researcher will drill and complete some 20 observation wells in the vicinity of the Fort Resolution sewage infiltration pit. Sample groundwater and analyze it for sewage derived contaminants and coliform bacteria. A report will be prepared with recommendations based on the findings and submitted to relevant agencies in the N.W.T....

Influence of the Slave River on Great Slave Lake
Principal Investigator: Evans, Marlene S.
Licensed Year(s): 1992
Summary: The Researchers will collect a series of sediment and water samples. These will be analyzed for plant nutrients, concentration of microscopic plant cells, bacteria, suspended solids, dissolved oxygen and organic contaminants. Microscopic animals will also be netted. They will determine the abundance and composition of the animals and conduct experiments to measure their feeding rates and fat cont...

Suphur bacteria and chemical analysis of two meromictic lakes
Principal Investigator: Dickman, Mike
Licensed Year(s): 1988
Summary: To investigate photosynthetic sulphur bacteria present in two meromictic lakes; to determine chemical and biological characteristics of two meromictic lakes (water does not turn over and bottom layer is without oxygen)...
