Quasi-periodic VLF emissions and concurrent magnetic pulsations seen at L = 4
Read more of: Quasi-periodic VLF emissions and concurrent magnetic pulsations seen at L = 4The first observations are presented from Halley, Antarctica, of quasi-periodic (QP)_VLF intensity variations modulated at the frequency of concurrent Pc3 magnetic pulsations. Seen on broadband frequency-time plots, the QP emissions […]

A theoretical determination of the characteristic equation of snow in the pendular regime
Read more of: A theoretical determination of the characteristic equation of snow in the pendular regimeRecent mathematical models treat a natural snow-pack as a mixture body consisting of solid ice grains, liquid water, and a gas made up of air and water vapour. Such a […]

A mixture theory for a phase-changing snowpack
Read more of: A mixture theory for a phase-changing snowpackThe continuum theory of mixtures is used as the mathematical framework for a four-constituent model of a natural snowpack. The general conservation equations in point form are derived from appropriate […]

Chemical evidence in polar ice cores from dielectric profiling
Read more of: Chemical evidence in polar ice cores from dielectric profilingThe dielectric stratigraphy of a 130 m ice core from Dolleman Island, Antarctic Peninsula, shows large variations in the dielectric relaxation process and in conductivity. A comparison with the chemical […]

Regional aeromagnetic anomalies in Ellsworth Land: Crustal structure and Mesozoic microplate boundaries within West Antarctica
Read more of: Regional aeromagnetic anomalies in Ellsworth Land: Crustal structure and Mesozoic microplate boundaries within West AntarcticaThe structural relationship between West Antarctic crustal blocks has remained uncertain due to a lack of information concerning sub‐ice crustal structure. A regional aeromagnetic reconnaissance of Ellsworth Land between 72 […]
