1. Lithostratigraphy and volcanic evolution of Deception Island, South Shetland Islands

   Deception Island is the most active volcano in the Antarctic Peninsula region. It is a large basalt–andesite shield volcano with a 10 km-wide restless caldera (Port Foster) and a complicated […]

2. Lithofacies Architecture and Construction of Volcanoes Erupted in Englacial Lakes: Icefall Nunatak, Mount Murphy, Eastern Marie Byrd Land, Antarctica

   Mount Murphy is a large Miocene shield volcano flanked by several small basaltic satellite centres that were erupted beneath a thick (> 200 m) ice sheet. Three empirical models illustrating […]

3. History of Oligocene erosion, uplift and unroofing of the Transantarctic Mountains deduced from sandstone detrital modes in CRP-3 drillcore, Victoria Land basin, Antarctica

   Detrital modes determined on 68 sandstone samples from CRP-3 drillcore indicate a continuation of the dynamic history of uplift-related erosion and unroofing previously documented in CRP-1 and CRP-2/2A. The source […]

4. Physical, chemical and biological processes in Lake Vostok and other Antarctic subglacial lakes

   Over 70 lakes have now been identified beneath the Antarctic ice sheet. Although water from none of the lakes has been sampled directly, analysis of lake ice frozen (accreted) to […]

5. Inland Thinning of Pine Island Glacier, West Antarctica

   The Pine Island Glacier (PIG) transports 69 cubic kilometers of ice each year from ∼10% of the West Antarctic Ice Sheet (WAIS). It is possible that a retreat of the […]

7. A tentative chronology for the EPICA Dome Concordia Ice Core

   A tentative age scale (EDC1) for the last 45 kyr is established for the new 788‐m EPICA Dome C ice core using a simple ice flow model. The age of […]

8. Geomorphological sketch map of the Fossil Bluff area (Alexander Island, Antarctica) mapped from aerial photographs

   A geomorphological sketch map of the Fossil Bluff area, showing the main morphological characteristics was prepared from aerial photographs taken by the British Antarctic Survey in 1995. Landforms and deposits […]

9. Rock debris in an Antarctic ice shelf

   We have discovered a band of stones and coarse sand in the Ronne Ice Shelf, Antarctica, some 60m above the ice shelf’s base, 40km from its seaward edge and 420km […]

10. (Poly)phenolic compounds in pollen and spores of antarctic plants as indicators of solar UV-B: a new proxy for the reconstruction of past solar UV-B?

    The morphology, size and characteristics of the pollen of the plant species Antarctic hairgrass (Deschampsia antarctica, Poaceae) and Antarctic pearlwort (Colobanthus quitensis, Caryophyllaceae) are described by scanning electron microscopy and […]

11. Latest Neoproterozoic to Mid-Cambrian age for the main deformation phases of the Transantarctic Mountains: new stratigraphic and isotopic constraints from the Pensacola Mountains, Antarctica

    New isotopic ages and a fresh understanding of stratigraphic relations among siliciclastic strata in the Pensacola Mountains along the northern margin of the East Antarctic craton result in removal of […]

12. Ozone loss episodes in the free Antarctic troposphere, suggesting a possible climate feedback

    Sudden loss of tropospheric ozone well above the boundary layer was observed on three occasions at two coastal sites in Antarctica in spring 1995. Back trajectories show that the air […]
