The fractionation of sea salt and acids during transport across an Antarctic ice shelf
Read more of: The fractionation of sea salt and acids during transport across an Antarctic ice shelfAnalyses of Cl−, NO3−, SO42−, Na and Mg made on a series of surface snow samples, collected at 4 km intervals along a 116 km traverse of the Fimbul Ice […]

Evidence for winter/spring denitrification of the stratosphere in the nitrate record of Antarctic firn cores
Read more of: Evidence for winter/spring denitrification of the stratosphere in the nitrate record of Antarctic firn coresA firn core from within the polar vortex in the Weddell Sea sector of Antarctica shows nitrate peaks that occur in the spring or early summer. They are far less […]

Plasma flow bursts in the nightside auroral zone ionosphere and their relation to geomagnetic activity
Read more of: Plasma flow bursts in the nightside auroral zone ionosphere and their relation to geomagnetic activityWe examine the nature of flows in the nightside auroral zone ionosphere and their relationship with concurrent geomagnetic activity by studying a three-hour interval of ground-based radar, magnetometer array and […]

Dielectric properties of frozen clay and silt soils
Read more of: Dielectric properties of frozen clay and silt soilsThe dielectric properties of a clay and a silt soil have been studied at low water saturations at temperatures between −100°C and −15°C. The frequency range of the study (20 […]

Dielectric properties of ice containing acid and salt impurity at microwave and low frequencies
Read more of: Dielectric properties of ice containing acid and salt impurity at microwave and low frequenciesWe compare the microwave and low-frequency (LF) dielectric conductivity of natural and artificial ice as a function of impurity concentration and temperature. We find a linear dependence of conductivity on […]

High-resolution dielectric profiling of ice cores
Read more of: High-resolution dielectric profiling of ice coresA new method for high-resolution (3 mm) dielectric profiling of ice cores is described. The method measures the capacitance and conductance of the ice at a single frequency (chosen to […]

Lithostratigraphy of the uppermost Fossil Bluff Group (Early Cretaceous) of Alexander Island, Antarctica: history of an Albian regression
Read more of: Lithostratigraphy of the uppermost Fossil Bluff Group (Early Cretaceous) of Alexander Island, Antarctica: history of an Albian regressionThe Fossil Bluff Group of south-east Alexander Island contains strata ranging from Kimmeridgian to Albian in age and represents the infill of a fore-arc basin to the west of the […]
