2. Detection and attribution of Antarctic climate change

   The current understanding of climate changes that have occurred in the last 50 years over Antarctica is presented with a focus on: (i) a summer warming of the eastern Antarctic […]

3. Efficient flowline simulations of ice-shelf/ocean interactions: Sensitivity studies with a fully coupled model

   Thermodynamic flowline and plume models for the ice-shelf/ocean system simplify the ice and ocean dynamics sufficiently to allow extensive exploration of parameters affecting ice-sheet stability while including key physical processes. […]

4. East Antarctica’s Achilles heel

   The East Antarctic ice sheet is believed to be Earth’s most stable ice sheet. Changes in geochemical composition of offshore sediments suggest that its margin repeatedly retreated by at least […]

5. Corticosterone mediated costs of reproduction link current to future breeding

   Life-history theory predicts that costs are associated with reproduction. One possible mediator of costs involves the secretion of glucocorticoid hormones, which in birds can be measured in feathers grown during […]

6. The search for seismic signatures of movement at the glacier bed in a polythermal valley glacier

   A passive seismology experiment was conducted across the main overdeepening of Storglaciaren in the Tarfala valley, northern Sweden, to investigate the spatial and temporal distribution of basal microseismic waveforms in […]

7. Tropical convective transport and the Walker circulation

   We introduce a methodology to visualise rapid vertical and zonal tropical transport pathways. Using prescribed sea-surface temperatures in four monthly model integrations for 2005, we characterise preferred transport routes from […]

8. A climatology of strong wind events at McMurdo station, Antarctica

   The first climatology of strong wind events (SWEs) at McMurdo station, Antarctica based on the in situ observations and reanalysis fields is presented. SWEs occur throughout the year, but with […]

9. Global statistical evidence for chorus as the embryonic source of plasmaspheric hiss

   The origin of plasmaspheric hiss, the electromagnetic emission responsible for the gap between the inner and outer radiation belts, has been debated for over four decades. Recently, a new theory […]

10. Remotely induced warming of Antarctic Bottom Water in the eastern Weddell gyre

    Four repeat hydrographic sections across the eastern Weddell gyre at 30°E reveal a warming (by ~0.1°C) and lightening (by ~0.02–0.03 kg m−3) of the Antarctic Bottom Water (AABW) entering the […]

11. The taxonomy and palaeobiogeography of small chorate dinoflagellate cysts from the Late Cretaceous to Quaternary of Antarctica

    Small chorate dinoflagellate cysts are common in Upper Cretaceous to Quaternary sedimentary successions around the Antarctic margin. Taxonomic confusion surrounding dinoflagellate cysts and acritarchs of similar morphology throughout the southern […]

12. Mesoproterozoic subduction under the eastern edge of the Kalahari-Grunehogna Craton preceding Rodinia assembly: the Ritscherflya detrital zircon record, Ahlmannryggen (Dronning Maud Land, Antarctica)

    The ∼2000 m thick clastic and volcaniclastic sedimentary rock pile of the Mesoproterozoic Ritscherflya Supergroup is located near the eastern margin of the Archaean Grunehogna Craton of Dronning Maud Land […]
