Principal Investigator: Ballantyne, James
Licensed Year(s): 2000
Summary: This project will examine the adaptation of freshwater fish to low temperatures. The data to be collected includes blood and tissue samples from fish. These samples will be analyzed for enzymes, fats and proteins. These results will be compared to samples taken from other locations (e.g. Nunavut, southern waters). This work will provide important information relating the sensitivity of Arctic ...

Principal Investigator: Burn, Chris R
Licensed Year(s): 1997 1996 1995 1994 1993 1992 1991
Summary: The researcher will collect samples of ground ice in near-surface sediments and measure air, ground and lake temperatures. The information will be used to help understand how the permafrost in the area has changed in the last few thousand years, in order to determine what might happen in the future....

Principal Investigator: Melling, Humfrey
Licensed Year(s): 1996 1995 1994 1993 1992 1991 1990
Summary: The ice measurements are made by untended instruments operating beneath the sea throughout the year. The instruments to be retrieved in March 1994 were positioned in April 1993 and will be recovered by aircraft. The sonars will be re-deployed at the same locations to continue observations for another year. The survey of water properties by a lowered probe to 1500 m depth of the seafloor will be c...

Principal Investigator: Aitken, Alec E.
Licensed Year(s): 1993 1992
Summary: The researcher will collect samples of small organisms that live on the sea bottom in the Canon and Slidre Fiords of Ellesmere Island. These creatures include small worms, shrimp, starfish, clams and snails. Measurements will be collected on water temperature and the amounts of salt and oxygen in the water. These data will help to relate the distribution of species with the characteristics of ...

Principal Investigator: Dixon, O.A.
Licensed Year(s): 1993 1992 1990 1988
Summary: In the Arctic Islands, we are studying rocks and the fossils found within these rocks that were formed more than 400 million years ago in warm tropical seas. This study is expected to help in describing the temperatures, climate and water depths of these ancient seas. We are also studying the types of fossil corals and sponge-like animals that are not present in our seas today....

Principal Investigator: Graham, Mark S
Licensed Year(s): 1991
Summary: The study will involve capturing freshwater char to use in laboratory experiments. The body temperature of fish is the same as the water they live in. Therefore, arctic fishes live their lives at or near the freezing mark. This work will investigate the mechanical functions of Arctic Char hearts: how powerful, how much blood they can pump and what is a reasonable maximum work load....

Principal Investigator: Dean, Ken
Licensed Year(s): 1991 1990
Summary: Satellite imagery, hydrologic data and field measurements will be used to develop a computer model of the thawing of sea ice and freezing of water in this area. The investigators will drill a hole through the ice and measure water temperature, salinity and turbidity....

Principal Investigator: Hyatt, James A.
Licensed Year(s): 1990 1989 1988 1987
Summary: Mr. Hyatt is continuing his study to see if permafrost and ground ice are affecting the new water reservoir at Pangnirtung and at Pond Inlet....

Principal Investigator: Scheibli, Frank
Licensed Year(s): 1988
Summary: Frank Scheibli and Alex Wolfe are part of Dr. King's research party working on the Truelove Lowlands. They are sampling the waters of three larger lakes to record depths, temperatures, and chemical properties. They want to know how these things affect the formation of sediments on the bottom of the lake....

Principal Investigator: Moore, Robert M.
Licensed Year(s): 1988
Summary: to measure concentrations of some dissolved gases in ocean waters collected from depths of 100-500 m in order to trace the flow of cooled Atlantic waters into the Arctic basins...
