There are two primary goals of this project: 1) to determine whether relatively small Canadian Arctic rivers significantly contribute to the total volume of freshwater that drains through Davis Strait; and, 2) to determine if they are chemically distinct from larger North American rivers such as the Mackenzie and Yukon Rivers. To achieve these goals the research team propose to collect water sampl...

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 ...

The objectives of this research are to examine the impacts of climate and environmental change on freshwater ecosystems in the Inuvik region across a variety of spatial and temporal scales. Specifically, the team is examining the impacts of permafrost degradation and subsequent thaw slumping on freshwater ecosystems and the impact of climate change on tree growth in the Mackenzie Delta.

The overall goal of the expedition Tundra Northwest 1999 is to study geographic variation of terrestrial and freshwater ecosystems of the tundra. By using the CCG icebreaker Louis St. Laurent for transport and as a scientific platform the the expedition route will include a longitudinal gradient from Baffin Island to the northern coast of Alaska and a latitudinal gradient through the Canadian Arc...

There is increasing evidence that levels of solar UV-B radiation have begun to rise in the high Arctic. Little is known about microbial life-forms in the ecosystems of Arctic lakes and rivers and their UV-B resistance. A sampling hole will be drilled in the lake ice. These samples of zooplankton will be studied by a microscope. Samples of water and periphytic communites will also be taken. Underw...

To investigate the ecology and population genetics of crustacean zooplankton. To study the genetic diversity of the major species of copepods and their dispersal since deglaciation. To clarify the taxonomy and improve distribution records....
Principal Investigator:Sheath, Robert Licenced Year(s):
To clarify freshwater red algae classification by determining key stable and non-overlapping structural characteristics needed to clearly separate species. Collecting trips will be made to all major drainage basins of the Atlantic, Pacific and Arctic. Preserved samples will be analyzed by computerized microscopy and live samples will be cultured under varied growth conditions to induce potential ...
Principal Investigator:Boileau, Marc G. Licenced Year(s):
To continue investigations on the ecology and population genetics of crustacean zooplankton: to focus on the genetic diversity of the four major species of copepods inhabiting the freshwater ponds in the Arctic and the distribution and dispersal of these species since glaciation....
Principal Investigator:Beaton, Margaret Licenced Year(s):
To take water samples from ponds for a better understanding of the ecology and population genetics of the freshwater cladoceran species, Daphnia pulex....
