The Antarctic ice sheet has been losing mass over past decades through the accelerated flow of its glaciers, conditioned by ocean temperature and bed topography. Glaciers retreating along retrograde slopes (that is, the bed elevation drops in the inland direction) are potentially unstable, while subglacial ridges slow down the glacial retreat. Despite major advances in the mapping of subglacial bed topography, significant sectors of Antarctica remain poorly resolved and critical spatial details… Expand

Late Quaternary dynamics of the Lambert Glacier-Amery Ice Shelf system, East Antarctica
Abstract The Lambert Glacier-Amery Ice Shelf system (LGAISS) is the largest outlet glacier system in East Antarctica but its response to past climate variability is poorly constrained. In this study,Expand

Observed interannual changes beneath Filchner-Ronne Ice Shelf linked to large-scale atmospheric circulation
TLDR
New multi-annual observations from five hot-water drilled boreholes through Filchner-Ronne Ice Shelf show that since 2015 there has been an intensification of the density-driven ice shelf cavity-wide circulation in response to reinforced wind-driven sea ice formation in the Ronne polynya. Expand
Distribution and seasonal evolution of supraglacial lakes on Shackleton Ice Shelf, East Antarctica
Abstract. Supraglacial lakes (SGLs) enhance surface melting and can flex and fracture ice shelves when they grow and subsequently drain, potentially leading to ice shelf disintegration. However, theExpand
Constraining an Ocean Model Under Getz Ice Shelf, Antarctica, Using A Gravity‐Derived Bathymetry
Getz Ice Shelf, the largest producer of ice shelf meltwater in Antarctica, buttresses glaciers that hold enough ice to raise sea level by 22 cm. We present a new bathymetry of its sub‐ice shelfExpand
Rapid postglacial rebound amplifies global sea level rise following West Antarctic Ice Sheet collapse
TLDR
This work demonstrates that the outflux mechanism contributes ~1 meter of additional GMSL change within ~1 thousand years of the collapse of the West Antarctic Ice Sheet, and shows that this contribution to global mean sea level (GMSL) rise is small and occurs slowly. Expand

Diverse landscapes beneath Pine Island Glacier influence ice flow
TLDR
High-resolution maps are presented, acquired using ice-penetrating radar, of the bed topography across parts of Pine Island Glacier, showing diverse landscapes beneath the glacier fundamentally influence ice flow and present a challenge for modelling ice-sheet evolution and projecting global sea-level rise from ice-sheets loss.
