Spatial patterns in the evolution of Cenozoic dynamic topography and its influence on the Antarctic continent [PDF]

, 2013
Our knowledge of dynamic topography in Antarctica remains in an infancy stage compared to other continents. We assess the space-time variability in dynamic topography in Antarctica by analysing grids of global dynamic topography in the Cenozoic (and late

A Possible Solution to the Mystery of the ANITA Anomalous Events

Annalen der Physik, Volume 538, Issue 4, April 2026.
In 2006 and 2014, the Antarctic Impulsive Transient Antenna (ANITA), a balloon‐borne radio observatory flying over Antarctica, detected two strange upward‐going radio pulse events that have not yet been explained by our current understanding of physics.

Coupled Climate‐Ice‐Sheet Simulations Reveal Novel Teleconnection Between Northern Hemisphere Ice Sheets and the Antarctic Ice Sheet

Geophysical Research Letters
Coupled climate‐ice‐sheet modeling is still in its developing stage, and feedback processes between ice sheets and climate are still not yet fully understood.

Glacial dynamics (glaciology) [PDF]

Recent results are reviewed from studies of ice dynamics that relate to the objectives of the West Antarctic Ice Sheet initiative. The large amount of knowledge gained is emphasized.

Approximating ice sheet – bedrock interaction in Antarctic ice sheet projections

Abstract. The bedrock response to a melting ice sheet provides a negative feedback on ice mass loss. When modelling the future behaviour of the Antarctic Ice Sheet, accounting for the impact of bed deformation on ice dynamics can reduce predictions of future sea level rise by up to 40 % in comparison with scenarios that assume a rigid Earth.

Quantifying the feedback between Antarctic meltwater release and subsurface Southern Ocean warming [PDF]

Earth System Dynamics
The subsurface ocean around Antarctica is one of the primary drivers of mass loss from the Antarctic ice sheet through the basal melting of ice shelves.

Advances in modelling subglacial lakes and their interaction with the Antarctic ice sheet [PDF]

, 2016
Subglacial lakes have long been considered hydraulically isolated water bodies underneath ice sheets. This view changed radically with the advent of repeat-pass satellite altimetry and the discovery of multiple lake discharges and water infill ...

Antarctic last interglacial isotope peak in response to sea ice retreat not ice-sheet collapse

Nature Communications, 2016
The peak in Antarctic ice core isotope values, 128,000 years before present, was concurrent with a significantly warmer-than-present Antarctic climate.

Dating late Cenozoic erosional surfaces in Victoria Land, Antarctica, with cosmogenic neon in pyroxenes [PDF]

, 2017
We present 21Ne exposure ages of erosional glaciogenic rock surfaces on nunataks in northern Victoria Land, Antarctica: i) in the Prince Albert Mountains and ii) near Mesa Range.

Antarctic ice sheet discharge driven by atmosphere-ocean feedbacks at the Last Glacial Termination [PDF]

, 2016
Reconstructing the dynamic response of the Antarctic ice sheets to warming during the Last Glacial Termination (LGT; 18,000–11,650 yrs ago) allows us to disentangle ice-climate feedbacks that are key to improving future projections.
