2. Area protection in Antarctica: how can conservation and scientific research goals be managed compatibly?

   The footprint of human activities within Antarctica is increasing, making it essential to consider whether current conservation/protection of environmental and scientific values is adequate. The Antarctic protected area network has […]

3. Inversion for the density-depth profile of polar firn using a stepped-frequency radar

   Translating satellite measurements of ice sheet volume change into sea level contribution requires knowledge of the profile of density as a function of depth within the ice sheet, and how […]

4. Exploring Pandora’s Box: potential and pitfalls of low coverage genome surveys for evolutionary biology

   High throughput sequencing technologies are revolutionizing genetic research. With this ‘‘rise of the machines’’, genomic sequences can be obtained even for unknown genomes within a short time and for reasonable […]

5. Growth of the Antarctic octocoral Primnoella scotiae and predation by the anemone Dactylanthus antarcticus

   Growth rates in Antarctic marine ectotherms have been demonstrated to be slowed by two to five times compared to shallow-water temperate species, with no previous reports for octocorals. Here growth […]

6. Human influence on extratropical Southern Hemisphere precipitation

   Observations of extratropical Southern Hemisphere austral summer precipitation over recent decades show mid-latitude drying and high-latitude moistening. Here we show that the observed precipitation trends in two datasets are inconsistent […]

7. A new species of Eualus Thallwitz, 1891 and new record of Lebbeus antarcticus (Hale, 1941) (Crustacea: Decapoda; Caridea; Hippolytidae) from the Scotia Sea

   Eleven specimens representing two hippolytid genera, EualusThallwitz, 1892 and LebbeusWhite, 1847 were sampled recently from the Scotia Sea (1517–2598 m). Seven specimens are described and illustrated as Eualus amandae sp. […]

8. Potential sea-level rise from Antarctic ice-sheet instability constrained by observations

   Large parts of the Antarctic ice sheet lying on bedrock below sea level may be vulnerable to marine-ice-sheet instability (MISI)1, a self-sustaining retreat of the grounding line triggered by oceanic […]

9. Trends in Antarctic Peninsula surface melting conditions from observations and regional climate modelling

   Multidecadal meteorological station records and microwave backscatter time-series from the SeaWinds scatterometer onboard QuikSCAT (QSCAT) were used to calculate temporal and spatial trends in surface melting conditions on the Antarctic […]

10. Modelling the liquid-water vein system within polar ice sheets as a potential microbial habitat

    Based on the fundamental and distinctive physical properties of polycrystalline ice lh, the chemical and temperature profiles within the polar ice sheets, and the observed selective partitioning of bacteria into […]

11. A ‘hurricane-like’ polar low fuelled by sensible heat flux: high-resolution numerical simulations

    An unusually deep (961 hPa) hurricane-like polar low over the Barents Sea during 18–21 December 2002 is studied by a series of fine-mesh (3 km) experiments using the Weather Research […]

12. Influence of channelling on heating in ice-sheet flows

    Ice‐sheet flows can be channelled by perturbations in the basal topography or in the sliding coefficient. These lead to spatial variation in the steady profile, the flux and the dissipative […]
