Understanding Changes in the Freshwater Ecosystems and Drinking Water in Northern Canada
Principal Investigator: Spicer, Neal
Licensed Year(s): 2017
Summary: The Objectives of this research are to: 1) determine where the participating communities obtain their drinking water from within their home and while on the land and why; and determine the areas of each region that are considered valuable and important areas of water quality; and 2) determine what the concerns are concerning the sources of water, both within the homes and natural water sources, ...

Assessing the impact of small, Canadian Arctic river flows to the freshwater budget of the Canadian Archipelago
Principal Investigator: Alkire, Matthew B
Licensed Year(s): 2016 2015 2014
Summary: 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...

Improving Habitat Connectivity to Enhance Productive Capacity of Arctic Freshwater Ecosystems
Principal Investigator: Tonn, William
Licensed Year(s): 2014 2013 2012 2011 2010 2009
Summary: 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 ...

Examining the impacts of climate change on aquatic and terrestrial ecosystems of the Mackenzie region, NWT
Principal Investigator: Pisaric, Michael FJ
Licensed Year(s): 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009
Summary: 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. Lake s...

Tundra Northwest 1999
Principal Investigator: Karlqvist, Anders
Licensed Year(s): 1999
Summary: 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...

UV-B Impacts On The Microbial Food Web In High Arctic Freshwater Ecosystems
Principal Investigator: Vincent, W.F.
Licensed Year(s): 1994
Summary: 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...

Ecology and population genetics of freshwater invertebrates of the Arctic.
Principal Investigator: Boileau, Marc G.
Licensed Year(s): 1988 1987 1986
Summary: 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....

Freshwater Red Algae in North America
Principal Investigator: Sheath, Robert
Licensed Year(s): 1987
Summary: 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 ...

Licence #5127
Principal Investigator: Boileau, Marc G.
Licensed Year(s): 1985
Summary: 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....

Licence #5060
Principal Investigator: Beaton, Margaret
Licensed Year(s): 1985
Summary: To take water samples from ponds for a better understanding of the ecology and population genetics of the freshwater cladoceran species, Daphnia pulex....
