The Extent and Pattern of Historical Ocean Disposal in Iqaluit, Brewer Bay, Cape Dyer and Cape Hooper.
Principal Investigator: Harbicht, Stephen
Licensed 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.
Licensed 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.
Licensed 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
Licensed 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...

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....

Physical nature of sediments in the intertidal area
Principal Investigator: Gilbert, Robert
Licensed Year(s): 1982
Summary: To continue studies on the physical nature of the sediments in the intertidal area. Sound waves will be projected into the sediments to determine their thickness....
