Ice pumping observed in the crevasse likely contributes to the relative stability of the Ross Ice Shelf -- the world's largest by area, the size of France -- compared to Thwaites Glacier, the ...

High in a narrow, seawater-filled crevasse in the base of Antarctica’s largest ice shelf, cameras on the remotely operated Icefin underwater vehicle relayed a sudden change in scenery. Walls of ...

ITHACA, N.Y. – More than merely cracks in the ice, crevasses play an important role in circulating seawater beneath Antarctic ice shelves, potentially influencing their stability, finds Cornell ...

A team led by Peter Washam, an oceanographer and climate scientist at Cornell University, used Icefin to observe a crevasse near the grounding line of the Ross Ice Shelf in West Antarctica.

Despite being small in comparison to the size of the entire glacier, changes to the ice shelves could have wide-ranging implications for the whole glacier system and future sea-level rise. ... The ...

The Brunt ice shelf has a number of prominent cracks, including one called Chasm 1. It’s a massive feature – more than 50 m deep, 30 km long and 1 km wide in parts – that formed 30 years ago ...

Antarctic ice shelves can disappear astonishingly fast — sometimes in minutes or hours — as meltwater surges through cracks in their surface. And as the atmosphere warms, this phenomenon may ...

Two expeditions to the Thwaites Ice Shelf have revealed that it could splinter apart in less than a ... A basal crevasse that is 10 meters across might widen to 30 or even 50 meters within a ...

Antarctic ice shelf at risk of collapse within 100 years 01:26. A massive iceberg splintered off one of West Antarctica’s largest glaciers last year, and now, scientists have discovered the ...

The Shackleton Ice Shelf included the Conger-Glenzer Ice Shelf before it collapsed. ( Supplied: Sarah Thompson ) "However, when ice shelves thin, retreat, fracture, and crevasse, their buttressing ...
