GPR capabilities for ice thickness sampling of low salinity ice and for detecting oil-in-ice / by Louis Lalumiere. Ottawa - Ontario : Fisheries and Oceans Canada iv, 36p. ; 28 cm. Canadian contractor report of hydrography and ocean sciences No. 56, 2011 "Ocean Sciences Division, Maritimes Region, Fisheries and Oceans Canada, Bedford Institute of Oceanography, P.O.

During recent field surveys a ground-penetrating radar system (GPR) has been used over brackish water of Lake Melville (Labrador) and a tidal river in Prince Edward Island (P.E.I.) to test the capabilities of the GPR to monitor snow and ice properties. Tests of the performance of a Noggin 1000 GPR and Noggin 500 GPR to measure the thickness of brackish ice have been made and will be discussed in this report. Another application for the airborne GPR being explored was its capability to detect of oil in or below sea ice. This report documents other researchers work in this area and compares the measurement technique these researchers have proposed with the GPR processing technique used for snow and freshwater ice thickness. Also, the author gives his opinion on the likelihood of the success of GPR as an oil-in-ice detector. (Résumé en français).
