Radar sounding is a powerful geophysical approach for characterizing the subsurface
conditions of terrestrial and planetary ice masses at local to global scales. As a result, a wide …

A holistic review is given of the Southern Ocean dynamic system, in the context of the crucial
role it plays in the global climate and the profound changes it is experiencing. The review …

Ocean-driven basal melting of Antarctica's floating ice shelves accounts for about half of
their mass loss in steady state, where gains in ice-shelf mass are balanced by losses. Ice …

Predictions for sea-level rise this century due to melt from Antarctica range from zero to more
than one metre. The highest predictions are driven by the controversial marine ice-cliff …

Mass loss from the Amundsen Sea sector of the West Antarctic Ice Sheet has increased in
recent decades, suggestive of sustained ocean forcing or an ongoing, possibly unstable …

Abstract The Pope, Smith and Kohler glaciers, in the Amundsen Sea Embayment of West
Antarctica, have experienced enhanced ocean-induced ice-shelf melt, glacier acceleration …

Antarctic ice shelves moderate the contribution of the Antarctic Ice Sheet to global sea level
rise; however, ice shelf health remains poorly constrained. Here, we present the annual …

Knowledge gaps about how the ocean melts Antarctica's ice shelves, borne from a lack of
observations, lead to large uncertainties in sea level predictions. Using high-resolution …

Widespread ice shelf thinning has been recorded in the Amundsen Sea in recent decades,
driven by basal melting and intrusions of relatively warm Circumpolar Deep Water (CDW) …

The grounding line position of glaciers and ice shelves is an essential observation for the
study of the Earth's ice sheets. However, in some locations, such as the Antarctic Peninsula …
