Electrical Anisotropy in Sea Ice and a Dual-Polarization Radar System to Mitigate the Effects of Preferential Attenuation in Imaging Sea Ice
Preferential alignment in the physical structure of the sea ice crystal matrix results in anisotropy in the electrical properties of the bulk sea ice. Previous field data and our data demonstrate that both sea ice conductivity and its electrical anisotropy can impede ice thickness profiling using gr...

Preferential alignment in the physical structure of the sea ice crystal matrix results in anisotropy in the electrical properties of the bulk sea ice.
