Beaufort Marine Hazards / Integrated Beaufort Observatory
Principal Investigator: Melling, Humfrey
Licenced Year(s): 2017 2016
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...


Decadal Variability of Marine Hazards
Principal Investigator: Melling, Humfrey
Licenced Year(s): 2010
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...


PITSA (Pack Ice Thickness - Station A)
Principal Investigator: Melling, Humfrey
Licenced Year(s): 2002
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...


Ice Thickness Topography Study -Beaufort Sea
Principal Investigator: Melling, Humfrey
Licenced Year(s): 1996 1995 1994 1993 1992 1991 1990
Summary: The researchers will retrieve untended sonar instruments operating beneath the sea that were positioned in April 1994. After servicing, these instruments will be re-deployed at the same locations to continue the observations for another year. A survey of water water properties will be collected at about 20 sites in the offshore and observations made using a lowered probe to 1500 m depth or to t...


Beaufort Sea Ice Motion Programme - Mesoscale Flow Features Study
Principal Investigator: Melling, Humfrey
Licenced Year(s): 1988 1987
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...


Beaufort Sea Ice Motion Programme - Wintertime Hydrography
Principal Investigator: Melling, Humfrey
Licenced 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...


Licence #5027
Principal Investigator: Melling, Humfrey
Licenced Year(s): 1985
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....
