The Sensitivity of the Antarctic Ice Sheet to a Changing Climate: Past, Present, and Future
Reviews of Geophysics, 2020 The Antarctic Ice Sheet (AIS) is out of equilibrium with the current anthropogenic‐enhanced climate forcing. Paleoenvironmental records and ice sheet models reveal that the AIS has been tightly coupled to the climate system during the past and indicate ...

Satellite laser ranging (SLR) observations have long been relied upon for measuring changes in Earth's dynamic oblateness, C20 . This major component of Earth's time‐variable gravity field is not well observed by the Gravity Recovery and Climate ...

Mass balance of the Antarctic ice sheet
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2006The Antarctic contribution to sea-level rise has long been uncertain. While regional variability in ice dynamics has been revealed, a picture of mass changes throughout the continental ice sheet is lacking. Here, we use satellite radar altimetry to measure the elevation change of 72% of the grounded ice sheet during the period 1992–2003 ...

The Antarctic ice sheet and the triggering of deglaciations
Earth and Planetary Science Letters, 2004A new physical mechanism involving the Antarctic ice-sheet extent is able to link climatic and CO2 glacial–interglacial changes. It is furthermore able to explain many features of the glacial cycles, like the 100 kyr oscillations or the peculiarities of stage 11 (about 400 kyr BP).

Changes in the West Antarctic Ice Sheet
Science, 1991The portion of the West Antarctic ice sheet that flows into the Ross Sea is thinning in some places and thickening in others. These changes are not caused by any current climatic change, but by the combination of a delayed response to the end of the last global glacial cycle and an internal instability. The near-future impact of the ice sheet on global

Antarctica is the fifth largest continent on the Earth with an area of 14,200,000 km2. About 98% of the surface of Antarctica is covered by an ice sheet that is 2,000 m thick on average. The volume of the ice sheet has changed in the course of time and reached a maximum during the late Wisconsin (Weichselian) ice age about 20,000 years ago.

The Southern Ocean and its interaction with the Antarctic Ice Sheet
Science, 2020The Southern Ocean exerts a major influence on the mass balance of the Antarctic Ice Sheet, either indirectly, by its influence on air temperatures and winds, or directly, mostly through its effects on ice shelves.

Is the Antarctic ice sheet growing?
Nature, 1992A brief review is presented of recent observations of surface accumulation on Antarctica. It is concluded that it is as yet too early to say with confidence whether the ice sheet has recently been growing or shrinking, given the variability in accumulation pattern and the larger uncertainties in melting and calving.

Global dynamics of the Antarctic ice sheet
Climate Dynamics, 2002The total mass budget of the Antarctic ice sheet is studied with a simple axi-symmetrical model. The ice-sheet has a parabolic profile resting on a bed that slopes linearly downwards from the centre of the ice sheet into the ocean. The mean ice velocity at the grounding line is assumed to be proportional to the water depth.
