Ionospheric scintillation over Antarctica during the storm of 5-6 April 2010
Read more of: Ionospheric scintillation over Antarctica during the storm of 5-6 April 2010On 5 April 2010 a coronal mass ejection produced a travelling solar wind shock front that impacted the Earth’s magnetosphere, producing the largest geomagnetic storm of 2010. The storm resulted […]

Unexpected Fine-Scale Population Structure in a Broadcast-Spawning Antarctic Marine Mollusc
Read more of: Unexpected Fine-Scale Population Structure in a Broadcast-Spawning Antarctic Marine MolluscSeveral recent empirical studies have challenged the prevailing dogma that broadcast-spawning species exhibit little or no population genetic structure by documenting genetic discontinuities associated with large-scale oceanographic features. However, relatively […]

An observationally validated theory of viscous flow dynamics at the ice-shelf calving front
Read more of: An observationally validated theory of viscous flow dynamics at the ice-shelf calving frontAn analytical theory is developed for ice flow velocity in a boundary layer couplet at the calving front. The theory has simple quantitative characteristics that relate ice front velocity to […]

Correlative and dynamic species distribution modelling for ecological predictions in the Antarctic: a cross-disciplinary concept
Read more of: Correlative and dynamic species distribution modelling for ecological predictions in the Antarctic: a cross-disciplinary conceptDevelopments of future scenarios of Antarctic ecosystems are still in their infancy, whilst predictions of the physical environment are recognized as being of global relevance and corresponding models are under […]

Leadership in politics and science within the Antarctic Treaty
Read more of: Leadership in politics and science within the Antarctic TreatyFor over 50 years the Antarctic has been governed through the Antarctic Treaty, an international agreement now between 49 nations of whom 28 Consultative Parties (CPs) undertake the management role. […]

Patterns in the distribution of soil bacterial 16S rRNA gene sequences from different regions of Antarctica
Read more of: Patterns in the distribution of soil bacterial 16S rRNA gene sequences from different regions of AntarcticaSince the advent of 16SrRNAgene-based molecular analysis, an increasing amount of work has been conducted on the Antarctic soilbacterial community. The majority of such studies suggest that the Antarctic soil […]

Modeling the properties of plasmaspheric hiss: 2. Dependence on the plasma density distribution
Read more of: Modeling the properties of plasmaspheric hiss: 2. Dependence on the plasma density distributionWave propagation plays an important role in linking the chorus source in the plasma trough region and the hiss emission in the plasmasphere. We investigate the dependence of plasmaspheric hiss […]

Modeling the properties of plasmaspheric hiss: 1. Dependence on chorus wave emission
Read more of: Modeling the properties of plasmaspheric hiss: 1. Dependence on chorus wave emissionThere is increasing evidence that plasmaspheric hiss is formed by the evolution of a portion of chorus waves that are excited in the plasmatrough and propagate into the plasmasphere. Comparison […]

Precipitating radiation belt electrons and enhancements of mesospheric hydroxyl during 2004–2009
Read more of: Precipitating radiation belt electrons and enhancements of mesospheric hydroxyl during 2004–2009Energetic particle precipitation leads to enhancement of odd hydrogen (HOx) below 80 km altitude through water cluster ion chemistry. Using measurements from the Microwave Limb Sounder (MLS/Aura) and Medium Energy […]
