Beaufort Marine Hazards / Integrated Beaufort Observatory
chercheur principal: Melling, Humfrey
Année(s) de permis: 2017 2016
Résumé: 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...


Decadal Variability of Marine Hazards
chercheur principal: Melling, Humfrey
Année(s) de permis: 2010
Résumé: 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...


PITSA (Pack Ice Thickness - Station A)
chercheur principal: Melling, Humfrey
Année(s) de permis: 2002
Résumé: 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...


Ice Thickness Topography Study - Beaufort Sea
chercheur principal: Melling, Humfrey
Année(s) de permis: 1996 1995 1994 1993 1992 1991 1990
Résumé: The base for operations is the PCSP Base at Tuktoyaktuk. The ice measurements are made by untended instruments operating beneath the sea throughout the year. The instruments to be retrieved in March 1996 were positioned in April 1995. They will be recovered through the ice using aircraft-based logistics. The survey of water properties will be conducted at about 15 selected sites in the offshore...


Beaufort Sea Ice Motion Programme - Mesoscale Flow Features Study
chercheur principal: Melling, Humfrey
Année(s) de permis: 1988 1987
Résumé: 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...


Beaufort sea ice motion program - Wintertime hydrography
chercheur principal: Melling, Humfrey
Année(s) de permis: 1988 1987
Résumé: 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...


Licence #5027
chercheur principal: Melling, Humfrey
Année(s) de permis: 1985
Résumé: 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....
