2017 Tarsuit Caissons Removal Program
Principal Investigator: Clarke, Kim P
Licenced Year(s): 2017
Summary: The objective of this project is to refloat and remove the Tarsuit Caissons from Lease Area 117/D11-3-7. Following their removal, the research team will conduct the following evaluation of the affected site and adjacent area: 1) Side Scan Survey 2) Macro invertebrate Survey A sidescan/multibeam unit (Edgetech 6205, or similar) will be pole mounted on the bathymetry vessel and data will be col...

Addendum to ArcticNet licence # 15213
Principal Investigator: Levesque, Keith R
Licenced Year(s): 2015 2014 2013
Summary: The ArcticNet marine-based research program is carried out from the Canadian research icebreaker CCGS Amundsen. The multi-year sampling program is developed around 3 main research components: 1) a meteorology, ocean & sea ice component; 2) a marine resources and environment component; and 3) a geology/bathymetry component. 1) Meteorology, ocean & sea ice component The general objective of thi...

GXT 2008 Marine Vibroseis Research Project (Flex Wave Test)
Principal Investigator: Rice, Shawn L
Licenced Year(s): 2008
Summary: This licence was issued for the scientific research licence application number 782. The objective of GXT’s research is to gather data to identify, model and remove Flex Waves (acoustic waves that becomes trapped in the ice) from the records. Data will be gathered using geophones developed by GXT and new methods of recording and interpreting the data. The project will involve setting out line...

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 two years. Ice scouring processes, benthic habitats, abandoned artificial islands, pingo-like features, gas seeps, seafloor foundation conditions, subsea permafrost and coastal stability will be investigated. The Coast Guard vessel CCGS Nahidik will be used as the research platform...

Niglintgak Field Development 2005 Bathymetry Research Study
Principal Investigator: Seligman, Ben
Licenced Year(s): 2005 2004
Summary: Shell Canada Limited will be surveying the river bottom to see if it is practical to use a barge-mounted gas conditioning facility at the Niglintgak Gas Field in the Mackenzie Delta. The researchers will do a bathymetric survey to identify locations that are not wide enough and/or deep enough for barge passage. Bathymetry is the science of measuring water depths and showing the variations in dep...

Ice Thickness Topography Study - Beaufort Sea
Principal Investigator: Melling, Humfrey
Licenced Year(s): 1996 1995 1994 1993 1992 1991 1990
Summary: 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...

The Extent and Pattern of Historical Ocean Disposal in Iqaluit, Brewer Bay, Cape Dyer and Cape Hooper.
Principal Investigator: Harbicht, Stephen
Licenced Year(s): 1994
Summary: This study will be conducted from Canadian Coat Guard's icebreaker the Perrie Radisson. This study will consist of: a preliminary sidescan sonar survey to determine the distribution of material on the bottom; identification of objects using either a remote operating vehicle or divers in shallow water; and sampling of water, sediment and biota in the vicinity of selected objects. Some objects ide...

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...

Determination of the Spatial and Temporal Structure of the Compression of Wave Speed and Attenuation in Sea Ice
Principal Investigator: Rajan, S.D.
Licenced Year(s): 1992 1990
Summary: This study will assist in understanding the changes that take place in the structure of sea ice during different seasons. These data will help in determining the strength characteristics of sea ice....

Sounds generated by ice cracking
Principal Investigator: Farmer, David
Licenced Year(s): 1988
Summary: To measure sounds generated by ice cracks using seven hydrophones and an ice surface instrument package; to relate these sounds to the source mechanism; to model the ice cracking so as to recover bulk ice parameters from the observed signal...
