Antarctic ice shelf potentially stabilized by export of meltwater in surface river
Meltwater stored in ponds and crevasses can weaken and fracture ice shelves, triggering
their rapid disintegration. This ice-shelf collapse results in an increased flux of ice from …

Widespread movement of meltwater onto and across Antarctic ice shelves
Surface meltwater drains across ice sheets, forming melt ponds that can trigger ice-shelf
collapse,, acceleration of grounded ice flow and increased sea-level rise,,. Numerical …

Large subglacial lakes in East Antarctica at the onset of fast-flowing ice streams
Water plays a crucial role in ice-sheet stability and the onset of ice streams. Subglacial lake
water moves between lakes and rapidly drains, causing catastrophic floods. The exact …

Ice stream activity scaled to ice sheet volume during Laurentide Ice Sheet deglaciation
The contribution of the Greenland and West Antarctic ice sheets to sea level has increased
in recent decades, largely owing to the thinning and retreat of outlet glaciers and ice …

Switch of flow direction in an Antarctic ice stream
Fast-flowing ice streams transport ice from the interior of West Antarctica to the ocean, and
fluctuations in their activity control the mass balance of the ice sheet. The mass balance of …

Twenty-first-century warming of a large Antarctic ice-shelf cavity by a redirected coastal current
HH Hellmer, F Kauker, R Timmermann, J Determann… - Nature, 2012 - nature.com
The Antarctic ice sheet loses mass at its fringes bordering the Southern Ocean. At this
boundary, warm circumpolar water can override the continental slope front, reaching the …

Millennial-scale variability in Antarctic ice-sheet discharge during the last deglaciation
Our understanding of the deglacial evolution of the Antarctic Ice Sheet (AIS) following the
Last Glacial Maximum (26,000–19,000 years ago) is based largely on a few well-dated but …
