NWT RESEARCH DATABASE

Principal Investigator: Topham, David
Licensed Year(s): 1991
Summary: The Researcher and his team will map and measure sea ice in the southern Beaufort Sea. They will use nine ARGOS drift buoys and will operate a small remote submersible equipped with upward looking sonar....

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: Forbes, D.L.
Licensed Year(s): 1991 1990
Summary: Geophysical surveys will be carried out from a 40-foot vessel and from 16-foot rubber boats to deploy current meters at two sites in water depths approximately 2 meters, to collect beach, cliff and seabed sediment samples and to survey beach and cliff morphology using theodolites and surveyors instruments....

Principal Investigator: Melling, Humfrey
Licensed Year(s): 1988 1987
Summary: To obtain better understanding of the role which wintertime freezing over the Mackenzie shelf of the Beaufort Sea plays in maintaining the peculiar cold haocline of the Arctic Ocean. Measurements will also show light on the regional ice budget, and on the recycling of nutrients to the surface layer by the wintertime haline circulation. Field study involves the measurement of the temperature, sal...

Principal Investigator: Melling, Humfrey
Licensed Year(s): 1988 1987
Summary: To better describe oceanic flow variations on scales of 5-50 km over the Mackenzie shelf of the southern Beaufort Sea. The relationship between such variations, seafloor topography and shelf water baroclinici will be investigated. The uncertainty which such fluctuations introduce into deterministic models of pack-ice drift may be estimated from the data obtained....

Principal Investigator: Farmer, D.
Licensed Year(s): 1987
Summary: To study the generation of noise due to ice, the propagation of sound under ice, the character of noice prior to summer ice break-up and the seasonal variation of ice noise....

Principal Investigator: Stirling, Ian
Licensed Year(s): 1985
Summary: Use sub-ice recording to study distribution of overwintering populations of seals in relation to plynyas, sea ice conditions, patterns of freeze-up, distribution of ringed seal pupping areas, distribution of polar bears and proposed winter shipping lanes....

Principal Investigator: Jummpanen, Pauli
Licensed Year(s): 1984
Summary: 1. Collection of snow samples to find about the spreading of air pollution. 2. Making observations of ice formations and pressure ridges. 3. Observations of clothing for cold air conditions being used by members of the expedition. 4. Behaviour and capacity of man in arctic conditions....

Principal Investigator: Ward, John
Licensed Year(s): 1981
Summary: Aboard the ice-breaker "Kigoriak" experiments will be conducted on the levels and types of noise produced by the ship as it participates in the normal operational program. Very small explosives charges will be used (detonator caps) as part of the work....

Principal Investigator: Sherstone, David A.
Licensed Year(s): 1974
Summary: Studies on river ice, sea ice,a nd glaciers....
