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.

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 ...

Direct observations of melting, freezing, and ocean circulation in an ice shelf basal crevasse. Sci. Adv. 2023;(9):7638. doi: 10.1126/sciadv.adi7638. This article is a rework of a press release issued ...

Instead, if the ice shelves collapse, the researchers say that sea levels may rise even higher, thus affecting more of the coastline and causing more flooding around the world. This would not only ...

However, the Icefin robot, navigating a crevasse within the foundation of the Ross Ice Shelf, achieved the world's first 3D analysis of oceanic conditions within the grounding zone, effectively ...

These cracks probably formed as the floating part of the glacier, the ice shelf, flexes up and down with ocean tides. ... which seemed to fill the upper half of the crevasse.

Several years ago, the BAS decided that the growing Chasm-1 crack and another crevasse, known as the Halloween Crack, threatened its Halley Research Station on the Brunt Ice Shelf; and so eight of ...
