Subglacial water amplifies Antarctic contributions to sea-level rise
Subglacial water flow strengthens ice–ocean interactions and substantially increases Antarctica’s projected contribution to future sea‑level rise; results highlight the need to include hydrology in projections.

Evolution of the Antarctic Ice Sheet over the next three centuries from an ISMIP6 model ensemble
A 16‑model ISMIP6 ensemble projects <30 cm SLE by 2100 but up to 4.4 m by 2300 (6.9 m with ice‑shelf collapse); retreat timing varies while propagation rates are consistent, and model choice remains the leading uncertainty.

Sensitivity of the future evolution of the Wilkes Subglacial Basin ice sheet to grounding-line melt parameterizations
Quantifies how grounding-line melt parameterizations control long‑term evolution of the Wilkes Subglacial Basin and its sea‑level contribution; provides practical guidance for choosing melt schemes in projections.

Thermal structure of the Amery Ice Shelf from borehole observations and simulations
Open-borehole observations and 3D/1D Elmer/Ice simulations reveal a near‑isothermal basal marine‑ice layer and strong basal temperature gradients; we quantify how basal mass balance patterns control shelf rheology and dynamics.
