Ocean cavity regime shift reversed West Antarctic grounding line retreat in the late Holocene

Using ice sheet model and glacio-isostatic adjustment model simulations and paleoclimate proxies, this work demonstrates that the most likely cause of past West Antarctic grounding-line reversal was a regime shift from a warm to cold ocean cavity.

The far reach of ice-shelf thinning in Antarctica

Ice loss from Antarctica is sensitive to changes in ice shelves. Finite-element modelling reveals that localized ice-shelf thinning, particularly in locations vulnerable to warm water intrusion, can have far-reaching impacts via tele-buttressing.

Extensive retreat and re-advance of the West Antarctic Ice Sheet during the Holocene

Radiocarbon dating of sediment cores and ice-penetrating radar observations are used to demonstrate that the West Antarctic Ice Sheet has not retreated progressively during the Holocene epoch, but has instead showed periods of retreat and re-advance.

Sedimentary basins reduce stability of Antarctic ice streams through groundwater feedbacks

A machine-learning-based mapping of Antarctic subglacial geology suggests sedimentary basins lie beneath some of the most dynamic ice streams, increasing their vulnerability to rapid ice retreat.

Calving fluxes and basal melt rates of Antarctic ice shelves

An estimate of the mass balance components for all ice shelves in Antarctica indicates that about half of the ice-sheet surface mass gain is lost through oceanic erosion before reaching the ice front, and that the loss due to iceberg calving is about 34 per cent less than previously thought.

Antarctic ice-sheet loss driven by basal melting of ice shelves

Using satellite laser altimetry, basal melting of ice shelves is determined to be the main driver of Antarctic ice-sheet loss,with changing climate the likely cause.

Sub-ice-shelf sediments record history of twentieth-century retreat of Pine Island Glacier

Many glaciers and ice shelves in the West Antarctic Ice Sheet are retreating or thinning rapidly, but the triggering mechanism has been unclear; now, the retreat of Pine Island Glacier is found to have begun in the 1940s following warming El Niño events in the Pacific Ocean, showing that glacial retreat can continue long after an initial push from the climate.
