Marine Geohazard and Environmental Studies in the Southern Beaufort Sea
Principal Investigator: Côté, Michelle
Licensed Year(s): 2019 2018
Summary: The goals of this research are to ascertain the formation of marine pockmarks, which are circular depressions on the sea floor thought to have formed from the release of methane gas. The hypothesis is that these features are actively releasing gas to the atmosphere and that they are formed from degrading or thawing offshore permafrost. The research team intend to document the seabed characteris...


Beaufort Shelf Seabed Mapping Project
Principal Investigator: Blasco, Steve M
Licensed Year(s): 2009 2008 2007 2006 2005 2004 2003
Summary: The objective of the seabed mapping program is to conduct a regional survey of the Beaufort shelf. Ice scouring processes, benthic habitats, abandoned artificial islands, pingo-like features, gas seeps, seafloor foundation conditions, and subsea permafrost will be investigated. The Coast Guard vessel CCGS Nahidik will be used as the research platform to conduct offshore acoustic/sonar surveys ...


Bathymetric and Shallow Sediment Core Sampling in McKinley Bay, NWT
Principal Investigator: Hammer, Lorne
Licensed Year(s): 2006
Summary: Shell Exploration and Production Company (Shell) is proposing to mobilize the Mobile Offshore Drilling Unit (MODU), Kulluk, from McKinley Bay, Northwest Territories to offshore Alaska, to initiate preparations for an offshore exploration drilling program to be carried out over the next several years. The Kulluk has been inactive and moored in McKinley Bay since 1993. Prior to that, the Kulluk had ...


Spring Season Coastal Reseach in the Beaufort Region
Principal Investigator: Forbes, Donald L
Licensed Year(s): 2004
Summary: Safe and sustainable hydrocarbon development and potential impacts of climate change on coastal infrastructure and subsistence activities require improved knowledge and understanding of coastal and nearshore seabed properties, and coastal hazards such as...


Licence #7046
Principal Investigator: Macdonald, R.W.
Licensed Year(s): 1987
Summary: To continue the study and come to understand natural hydrocarbon distributions and primary productivity in the oil exploration zone of the Mackenzie Estuary. To predict the impact of projected industrial discharges of hydrocarbons, planned or accidental, by studying and model processes governing natural distributions of the same compounds....


Licence #5126
Principal Investigator: MacLean, Brian
Licensed Year(s): 1985
Summary: Shipborne marine geological and geophysical investigations in the Baffin Island region from CSS HUDSON - single channel and high resolution seismic reflection, magnetic, sidescan, and echosounder profiles, sampling by seabed rock core drill piston coring, IKU and other grabs, camera....


Licence #5045
Principal Investigator: MacLean, Brian
Licensed Year(s): 1985
Summary: Geological investigations of the seabed in marine areas of the Canadian Arctic Archipelago: to obtain grab samples, short core and seabed photography; approx. 60 stations over a grid pattern; experiment with through-the-ice seismic reflection data using small charges as sound source to obtain information on sediment thickness and shallow stratigraphy....


Licence #5017
Principal Investigator: Sauriol, Yvan
Licensed Year(s): 1985
Summary: To conduct Phase II of Through-the-Ice-Sounding Study. Measurements will be made on rifle shots aimed vertically at the ice from a platform and firing shots at the ice from a helicopter to develop a non-contact through-the-ice sounding method....


Licence #4005
Principal Investigator: de Heering, Philippe
Licensed Year(s): 1984
Summary: To carry out phase I of a bathymetric survey system. A tower will be built on the ice and a rifle (460 cal Weaterby) mounted on it. The rifle will be discharged into the ice and measurements made to determine the amount of sound transmitted to the water, the level of bottom echo detected in air etc....
