A two-phase model of electrical conduction in polar ice sheets

It has been suggested that the dc conductivity of polar ice sheets could be due to the presence of liquid layers at the grain boundaries. These layers would consist of a mixture of acids with water. We show that it is plausible that acids will be at three‐grain boundaries in polar ice. Using reliabl...
