Summary: The strategic objective of this expedition is continued long-term monitoring of Canadian Beaufort Sea. The specific objectives are: 1) to recover, service and re-deploy oceanographic moorings carrying instruments that measure ice thickness and ridging, storm waves, sea level, ocean current, temperature and salinity, mammal vocalization, underwater sound and plankton; and, 2) to visit oceanogra...

Summary: The objectives of this research project are: - To recover, service and re-deploy sub-sea moorings instruments for year-round measurement of ice thickness and ridging, storm waves, sea level, ocean current, temperature and salinity, mammal vocalization, ambient sound and plankton. - To complete ocean and seabed surveys near naturally occurring methane vents on the floor of the Beaufort Sea, usin...

Summary: This project will establish a baseline climate-monitoring site in the perennial ice zone of the Canada Basin. Mooring carrying instruments to measure thickness of drifting perennial pack ice will be kept at Station A on the 3000-m isobath in the Canada B...

Summary: As part of an on-going study, sonar instruments will be recovered through the ice at three locations on the continental shelf that is located north and east of Tuktoyaktuk. The sonars provide information about the motion, thickness and ridging of sea ice. A survey of seawater properties, including temperature and salinity, will also be conducted at selected sites....

Summary: To deploy 11 drifting buoys to improve description of oceanic flow variations on scales of 5-50 km over the Mackenzie shelf of the southern Beaufort Sea; to investigate the relationship between such variations, seafloor topography and shelf water baroclinicity; to estimate the uncertainty which such fluctuations introduce into deterministic models of pack-ice drift...

Summary: To improve understanding of the role which wintertime freezing over the Mackenzie Shelf of the Beaufort Sea plays in maintaining the peculiar cold halocline of the Arctic Ocean...

Summary: To install current meters and tide gauges beneath the sea surface to measure and record flow and sea-level for 12 months; pack ice motion and surface wind will be measured by drifting instruments for two months - to enable the prediction of ice motion several days in advance....
