1. Origins of plasmaspheric hiss

   Plasmaspheric hiss is an electromagnetic wave emission responsible for electron loss from the radiation belts, particularly in the slot region (2 < L < 3). There are two leading theories […]

2. Circumpolar response of Southern Ocean eddy activity to a change in the Southern Annular Mode

   Analysis of satellite altimeter data reveals anomalously high Eddy Kinetic Energy (EKE) in the Antarctic Circumpolar Current (ACC) during the period 2000–2002. Around 2–3 years earlier (1998), the circumpolar eastward […]

3. Monitoring microbial predator-prey interactions: an experimental study using fatty acid biomarker and compound-specific stable isotope techniques

   Naturally occurring microbial communities are complex, with autotrophs and heterotrophs often similarly sized and impossible to separate by conventional size fractionation approaches. However, if it was possible to identify specific […]

4. Year-round distribution of white-chinned petrels from South Georgia: relationships with oceanography and fisheries

   The white-chinned petrel Procellaria aequinoctialis is a medium-sized procellariiform with a circumpolar subAntarctic breeding distribution. Feeding during both day and night, and often competing aggressively for bait, offal and discards, […]

5. Cluster observations of broadband electromagnetic waves in and around a reconnection region in the Earth’s magnetotail current sheet

   We present an analysis of the electric and magnetic wave spectra on kinetic scales during several crossings of a reconnecting current sheet. The spectra were measured from 1 Hz or […]

6. Anomalous resistivity and the non-linear evolution of the ion-acoustic instability

   Collisionless magnetic reconnection requires the violation of ideal MHD by various kinetic-scale effects whose relative importance is uncertain. Recent research has highlighted the potential importance of wave-particle interactions by showing […]

7. Subglacial sediments as a control on the onset and location of two Siple Coast ice streams, West Antarctica

   Laterally continuous subglacial sediments are a necessary component for ice streaming in the modern onset regions of the ice streams draining the Siple Coast of West Antarctica on the basis […]

8. Environmental constraints on life histories in Antarctic ecosystems: tempos, timings and predictability

   Knowledge of Antarctic biotas and environments has increased dramatically in recent years. There has also been a rapid increase in the use of novel technologies. Despite this, some fundamental aspects […]

9. Metabolism and development in pelagic larvae of Antarctic gastropods with mixed reproductive strategies

   The Antarctic gastropods Marseniopsis mollis (Smith, 1902) and Torellia mirabilis (Smith, 1907) lay eggs in the late austral summer and autumn; these hatch the following late winter and early summer. […]

10. Slow growth of Antarctic bryozoans increases over 20 years and is anomalously high in 2003

    Some organisms are particularly appropriate models for investigation of variability in time and space for given environments. The erect bryozoan Cellarinella nutti, an endemic Antarctic species, is one such organism: […]

11. Analytical solutions for the effect of topography, accumulation rate and lateral flow divergence on isochrone layer geometry

    The effect of spatial variations in ice thickness, accumulation rate and lateral flow divergence on radar-detected isochrone geometry in ice sheets is computed using an analytical method, under assumptions of […]

12. A most isolated benthos: coastal bryozoans of Bouvet Island

    Bouvet Island is, uniquely, thousands of km from the next nearest land, even other islands. Its Southern Ocean location, isolation and the exposure of its surrounding cliffs have resulted in […]
