Extreme natal philopatry in female Antarctic fur seals (Arctocephalus gazella)
Read more of: Extreme natal philopatry in female Antarctic fur seals (Arctocephalus gazella)Natal philopatry is an important component of mammalian behaviour but is difficult to study in natural vertebrate populations due to the requirement for long-term individual-based spatial observations. Consequently, we quantified […]

The contribution of wave-particle interactions to electron loss and acceleration in the Earth’s radiation belts during geomagnetic storms
Read more of: The contribution of wave-particle interactions to electron loss and acceleration in the Earth’s radiation belts during geomagnetic stormsThe Earth’s radiation belts are a hazardous environment that pose a risk to astronauts and spacecraft on orbit. Having been discovered in 1958, there is renewed interest on the part […]

Efficient diffuse auroral electron scattering by electrostatic electron cyclotron harmonic waves in the outer magnetosphere: A detailed case study
Read more of: Efficient diffuse auroral electron scattering by electrostatic electron cyclotron harmonic waves in the outer magnetosphere: A detailed case studyThis paper is a companion to a paper by Liang et al. (2011) which reports a causal connection between the intensification of electrostatic ECH waves and the postmidnight diffuse auroral […]

Polymetamorphism in the NE Shackleton Range, Antarctica : constraints from petrology and U-Pb, Sm-Nd, Rb-Sr TIMS and in situ U-Pb LA-PIMMS dating
Read more of: Polymetamorphism in the NE Shackleton Range, Antarctica : constraints from petrology and U-Pb, Sm-Nd, Rb-Sr TIMS and in situ U-Pb LA-PIMMS datingMetapelitic rock samples from the NE Shackleton Range, Antarctica, include garnet with contrasting zonation patterns and two age spectra. Garnet porphyroblasts in K-rich kyanite-sillimanite- staurolite-garnet-muscovite-biotite schists from Lord Nunatak show […]

Two-dimensional structure of long-period pulsations at polar latitudes in Antarctica
Read more of: Two-dimensional structure of long-period pulsations at polar latitudes in AntarcticaTwo-dimensional (2-D) statistical distributions of spectral power and coherence of polar geomagnetic variations with quasi-periods about 10 min are analyzed using data from magnetometer arrays in Antarctica. Examination of the […]
