Sulphuric acid at grain boundaries in Antarctic ice
It has been suggested1,2 that acids in the cold polar ice sheets may exist as aqueous mixtures at grain boundaries. This assumption can correctly predict the d.c. conductivity of polar […]

High-resolution anion profiles of Cl-, NO3- and SO4 2− are presented for two cores from the Antarctic Peninsula. A 47.2 m core from a site on the Palmer Land plateau […]
A 130 m long ice core has been dielectrically profiled. From an analysis of the measurements, we obtain a profile of the high-frequency (radio-echo) conductivity. This profile has been represented […]
A steep reverse fault at Engel Peaks, Antarctic Peninsula, cuts granophyre and overlying volcanic rocks and incorporates a lower angle zone or ‘fault step’. The reverse fault step differs from […]
