After months of ‘hanging by a thread’, a vast iceberg the size of Norfolk has finally broken off Antarctica’s Larsen C Ice Shelf. Around 30 m (98 feet) of this 190 m (623 feet) thick block of ice sits above the sea surface. Scientists now have...

A new study led by NASA's glaciologists Jay Zwally, says that an increase in Antarctic snow accumulation that began 10 000 years ago is currently adding enough ice to the continent to outweigh the increased losses from its thinning glaciers. The research...

Using a novel, helicopter-borne sensor to penetrate the surface of large swathes of terrain, a team of researchers supported by the National Science Foundation (NSF) has gathered compelling evidence that beneath Antarctica's ice-free McMurdo Dry Valleys lies a salty

South Pole Ice Core (SPICE) project is a joint effort by researchers from the University of Washington and the University of California, Irvine to 'dig' 40 000 years into climate history at the planet's southernmost tip. The ice core will be drilled to a dep

One of the larger eruptions of Antarctica's Mount Erebus this year occurred at 09:12 UTC on December 4, 2014 and ejected bombs onto the summit cone of Erebus, Mount Erebus Volcano Observatory (MEVO) reports.Mount Erebus is one of several volcanoes in the McMurdo Vol

Sections of Antarctica's frozen desert can experience hundreds of micro-quakes an hour due to ice deformation. These quakes are also called icequakes and they are a usual occurrence on Antarctica. However, after the 8.8-magnitude earthquake that hit C

Parts of ancient Antarctica were as warm as today's California coast, and polar regions of the southern Pacific Ocean registered 21st-century Florida heat, according to scientists using a new way to measure past temperatures.The findings, published the week of A
