N2 - Anisotropy in the conductivity structure of sea ice results from the preferential alignment of brine channels in the ice crystal matrix. Attenuation of radar waves traveling within the ice depends on the polarization of the electric field with respect to the orientation of these channels. Here, radar wave data collected over sea ice using 500 MHz antennas demonstrate the effect of conductivity anisotropy on radar wave propagation. Ongoing research has previously demonstrated that ice-penetrating radar can successfully image anomalies associated with thin layers of oil in and under sea ice. This methodology has applications for oil spill remediation in Arctic environments. We use a multi-channel radar system to simultaneously collect radar data in both perpendicular and parallel polarizations relative to a survey line and jointly process the resulting data to minimize the problems caused by the effect of conductivity anisotropy and thereby improve oil detection potential.
