Marine Geohazard and Environmental Studies in the Southern Beaufort Sea
chercheur principal: Côté, Michelle
Année(s) de permis: 2019 2018
Résumé: 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
chercheur principal: Blasco, Steve M
Année(s) de permis: 2009 2008 2007 2006 2005 2004 2003
Résumé: 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
chercheur principal: Hammer, Lorne
Année(s) de permis: 2006
Résumé: 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 ...

Licence #4005
chercheur principal: de Heering, Philippe
Année(s) de permis: 1984
Résumé: 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....
