    Notes: [Auszug] Georesistivity measuring techniques have been applied to the sounding of ice masses many times during the last 25 years. Studies on European glaciers indicate that temperate ice has a resistivity of about 108 urn (refs 1-6). Mono- and polycrystalline ice grown slowly from pure water in the ...

    Sea salt dependent electrical conduction in polar ice (1992)

    Description: A 45 m length of ice core from Dolleman I., Antarctic Peninsula, has been dielectrically analyzed at 5 cm resolution using the dielectric profiling (DEP) technique. The core has also been chemically analyzed for major ionic impurities. A statistical analysis of the measurements shows that the LF (low frequency) conductivity is determined both by neutral salt and acid concentrations. Salts (probably dispersed throughout the ice fabric) determine the dielectric conductivity. The salt conduction mechanism is probably due to Bjerrum L defects alone, created by the incorporation of chloride ions in the lattice. Samples of ice from beneath the Filchner-Ronne Ice Shelf were also measured, and display a similar conduction mechanism below a solubility limit of about 400 micromoles of chloride. The temperature dependence of the neutral salt, acid and pure ice contributions to the LF conductivity of natural ice between -70 C and 0 C is discussed. These results allow a comprehensive comparison of dielectric and chemical data from natural ice.
