1. Flow at ice-divide triple junctions: 2. Three-dimensional views of isochrone architecture from ice-penetrating radar surveys

   Ground-based surveys of ice-divide triple junctions in two Antarctic ice rises, the Fletcher Promontory and Berkner Island, have been carried out using low-frequency ice-penetrating radars. These surveys have focused on […]

2. Interglacial and glacial variability from the last 800 ka in marine, ice and terrestrial archives

   We have compiled 37 ice, marine and terrestrial palaeoclimate records covering the last 800 000 years in order to assess the pattern of glacial and interglacial strength, and termination amplitude. […]

3. Chorus-driven resonant scattering of diffuse auroral electrons in nondipolar magnetic fields

   We perform a comprehensive analysis of resonant scattering of diffuse auroral electrons by oblique nightside chorus emissions present along a field line with an equatorial crossing of 6 R(E) at […]

4. Food for thought: risks of non-native species transfer to the Antarctic region with fresh produce

   To understand fully the risk of biological invasions, it is necessary to quantify propagule pressure along all introduction pathways. In the Antarctic region, importation of fresh produce is a potentially […]

5. Particle size measurement of diatoms with inference of their properties: comparison of three techniques

   Diatom-rich sediments are common in several oceanic regions, especially the Southern Ocean. Some of these are strongly affected by bottom currents and are expected to be sorted by the flow. […]

6. Demographic parameters of black-browed albatrosses Thalassarche melanophris from the Falkland Islands

   Black-browed albatrosses Thalassarche melanophris are currently classified as globally endangered. The most important populations of this species are believed to be declining due to, amongst other factors, unsustainable levels of […]

7. Subduction over the Southern Indian Ocean in a high-resolution atmosphere-ocean coupled model

   This study examines the subduction of the Subantarctic Mode Water in the Indian Ocean in an ocean–atmosphere coupled model in which the ocean component is eddy permitting. The purpose is […]

8. How likely was a green Antarctic Peninsula during warm Pliocene interglacials? : a critical reassessment based on new palynofloras from James Ross Island

   The question of whether Pliocene climate was warm enough to support a substantial vegetation cover on Antarctica is of great significance to the ongoing and controversial debate on the stability […]

9. Lead-radium dating provides a framework for coordinating age estimation of Patagonian toothfish (Dissostichus eleginoides) between fishing areas

   Patagonian toothfish (Dissostichus eleginoides) or ‘Chilean sea bass’ support a valuable and controversial fishery, yet their life history is not well understood and longevity estimates range from ~20 to >50 […]

11. The need to implement the Convention on Biological Diversity at the high latitude site, South Georgia

    The multilateral failure to apply the Convention on Biological Diversity (CBD) by the target year 2010 was headline news as are the accelerating climatic changes which dictate its urgency. Some […]
