Beaufort Shelf Seabed Mapping Project
Principal Investigator: Blasco, Steve M
Licenced 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 over the next four years. Ice scouring processes, benthic habitats, abandoned artificial islands, pingo-like features, gas seeps, seafloor foundation conditions, sub-sea permafrost and coastal stability will be investigated. The Coast Guard vessel CCGS Nahidik will be used to collect seabed sedi...


Ice Scour Disturbance and the Structure of Arctic Marine Benthic Communities.
Principal Investigator: Conlan, Kathleen E.
Licenced Year(s): 1994 1993 1992
Summary: Researchers acoustically profile the seabed in the are of Resolute by side scan sonar in order to obtain an aerial view of the seabed and locate scours known from previous years and created over the last winter. Researchers then scuba dive on these scours & count the large animals, collect small animals and measure the physical and chemical characteristics of the scours. This will help to determ...


Surficial Geology of the Canadian Beaufort Continental Shelf
Principal Investigator: Blasco, Steve M
Licenced Year(s): 1990
Summary: The amphibious vehicle will be mounted with an echosounder, sidescan sonar, subbottom and seismic profiling equipment to run a test survey along the coast of the Tuktoyaktuk Peninsula. The CCGS NAHIDIK will tow a sidescan sonar system over the seafloor to rerun track lines surveyed in previous years to allow for the detection and measurement of the characteristics of new scours on the seafloor of ...

Principal Investigator: MacLean, Brian
Licenced Year(s): 1987
Summary: To provide information on the composition, thickness, and geotechnical properties of the seafloor sediments, as well as the effect of ice or current scouring, or slumping, or other modifying influences....
