3 The Interaction of Electromagnetic Waves with Ice
Fig. 3.3 The temperature dependencies of different transport parameters: self-diffusion coefficient,
D (m 2 /s); static conductivity, σ dc (S/cm), high-frequency conductivity, σ D1 (S/cm), and relaxation
frequency, ν D1 , for water and ice. The dashed vertical line corresponds to the melting point. Circles
are experimental data, lines are linear fit with parameters given in Table 3.2
