    The Ross Ice Shelf is an ice shelf that covers the southern half of the Antarctic Ross Sea . With an area of ​​around 525,000 km² (source: AWI ; other sources assume 487,800 km²), the ice shelf is only slightly smaller than France and thus the largest ice shelf area in Antarctica .

    nature

    The almost vertical, seaward front (edge) of the Ross Ice Shelf, the Ross Barrier , extends over a length of 600 to 800 km and rises 20 to 50 meters above sea level. New measurement results on the Ross Ice Shelf show the risk of this ice shelf disintegrating.

    history

    The Ross Ice Shelf is named after the English explorer and navigator James Clark Ross , who discovered it on January 28, 1841. Ross mapped the face of the ice sheet east to about 160 degrees west. The ice shelf was entered for the first time in January 1900 by participants in the Southern Cross Expedition (1898–1900) led by the Norwegian polar explorer Carsten Egeberg Borchgrevink . Most of the Ross Ice Shelf is in the Ross Dependency claimed by New Zealand . In 1912 the Ross Ice Shelf became the final resting place for polar explorer Robert Falcon Scott and his expedition members.
