The polar expression of ENSO and sea-ice variability as recorded in a South Pole ice core [PDF]
, 2002 An annually dated ice core recovered from South Pole (2850 m a.s.l.) in 1995, that covers the period 1487–1992, was analyzed for the marine biogenic sulfur species methanesulfonate (MS).

Antarctic subglacial hydrology: current knowledge and future challenges [PDF]
, 2014 Flood-carved landforms across the deglaciated terrain of Victoria Land, East Antarctica, provide convincing geomorphological evidence for the existence of subglacial drainage networks beneath the Antarctic ice sheet, and motivate research into the ...

New modeling of the Vostok ice flow line and implication for the glaciological chronology of the Vostok ice core [PDF]
, 2004 International audienceWe have used new spaceborne (elevation) and airborne (ice thickness) data to constrain a 2D1/2 model of snow accumulation and ice flow along the Ridge B‐Vostok station ice flow line (East Antarctica). We show that new evaluations of

The Dominion Range Ice Core, Queen Maud Mountains, Antarctica - General Site and Core Characteristics with Implications [PDF]
, 2017 The Transantarctic Mountains of East Antarctica provide a new milieu for retrieval of ice-core records. We report here on the initial findings from the first of these records, the Dominion Range ice-core record.

Journal of GlaciologyThe grounding zones of Antarctic ice shelves are among the continent’s most dynamic regions, where floating ice shelves buttress grounded upstream ice and tidal forcing drives cyclic flexure at the ice–ocean–bed interface.

Tide-modulated ice motion and seismicity of a floating glacier tongue in East Antarctica
Annals of Glaciology, 2019 We recorded the ice motion and icequakes on the floating part of Langhovde Glacier in East Antarctica to better understand the dynamic behavior of ice shelves and floating tongues.

Glaciological Modelling of the Late Cenozoic East Antarctic Ice Sheet: Stability or Dynamism? [PDF]
Geografiska Annaler: Series A, Physical Geography, 1993 On the basis of geological arguments, two widely different hypotheses have been proposed for the late-Tertiary glacial history of East Antarctica. Theseinvoke ice-sheet reconstructions ranging from severe glaciation completely burying the Transantarctic Mountains to a situation, in which an unstable EastAntarctic Ice Sheet repeatedly collapses to ...
