A Paleolimnological Approach to Environmental Reconstruction on the Pre-Foxe Terrain of Cumberland Peninsula, Baffin Island
Principal Investigator: Wolfe, Alexander P.
Licensed Year(s): 1992 1991 1990
Summary: During the last glacial period, 110,000 to 5,000 years to present some lakes escaped glaciation. The Researcher will retrieve sediment cores from three upland lakes to investigate the physical responses of the sediments and the biological responses of algae toward this climatic event....


Nutrition and Distribution of Arctic Marine Zooplankton in Relation to the Physical Environment
Principal Investigator: Gustavson, Kent
Licensed Year(s): 1991 1990
Summary: The Researcher will continue to study the distribution of phytoplankton and zooplankton in the Barrow Strait area. The herbivourous plankton species which feed on the marine algae and phytoplankton is the first step in the arctic food chain. It is the herbivorous plankton which is the source of food for other animals which ultimately provides food for all other higher arctic animals....


Northern Ellesmere Wintering Over Project 1990/91
Principal Investigator: Bird, D. le R.
Licensed Year(s): 1990
Summary: The researcher will carry out monthly collections of snow for analysis; ice algae from ice cores; ice crystals for analysis; snow samples during snow storms and a three-hourly traditional meteorology program....


To determine the productivity of the most important components of marine mammal food chains
Principal Investigator: Welch, Harold
Licensed Year(s): 1988
Summary: To study epontic algae and amphipods in Chesterfield inlet area; to determine dynamics of Si and N as essential nutrients; to sample stomach contents of hunter-killed seals for food habit analysis....


To determine the productivity of the most important components of marine mammal food chains.
Principal Investigator: Welch, Harold
Licensed Year(s): 1993 1992 1991 1990 1988 1987
Summary: To study epontic algae and amphipods in Resolute area; phytoplankton, kelp and Mya truncata in Barrow Strait, from small vessels. To study hunter-killed seal parts for food habit analysis....


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 #5142
Principal Investigator: Sprague, J. B.
Licensed Year(s): 1985
Summary: To collect samples of common amphipod crustaceans, microscopic crustaceans, and algae in order to measure their cadmium content....

Principal Investigator: Williams, Kerstin
Licensed Year(s): 1985
Summary: Comparative studies of living diatom flora during and after ice break-up with diatom thanatocoenoces (death assemblages) preserved in the sediments....


Licence #4094
Principal Investigator: Sprague, John B.
Licensed Year(s): 1984
Summary: To collect samples of common amphipod crustaceans, microscopic crustaceans, and algae in order to measure their cadmium content....


Licence #1785
