STUDY OF SEA ICE USING IMPULSE RADAR

Although sea ice presents one of the most serious obstacles to ocean engineering under Arctic conditions, techniques to measure and monitor its properties, such as thickness and strength, are still being developed. This ability is particularly important since the properties of sea ice vary dramatically both spatially and temporally. This paper presents results from studies made of first year fast ice near Newfoundland. Particular attention is given to estimating the electrical properties of ice using impulse radar. The complex reflection coefficient from the ice surface is determined using Fourier techniques, and this approach is a promising first step toward quick in situ or remote estimates of the electrical properties of the ice. These properties are significant, since both the electrical and the mechanical properties of sea ice are dominated by the influence of its brine volume fraction.
