New Antarctic heat map reveals sub-ice hotspots

New Antarctic heat map reveals sub-ice hotspots

An international team of scientists, led by British Antarctic Survey (BAS), has produced a new map showing how much heat from the Earth’s interior is reaching the base of the Antarctic Ice Sheet. The map was published Monday, November 13, 2017, in the journal…

Mantle plume, a geothermal heat source under West Antarctic ice sheet

Mantle plume, a geothermal heat source under West Antarctic ice sheet

A new study adds to evidence that a geothermal heat source called a mantle plume lies deep below Antarctica's Marie Byrd Land, explaining some of the melting that forms lakes and rivers under the ice sheet. Although the heat source isn't a new or increasing…

Scientists uncover largest volcanic region on Earth under West Antarctica

A remote survey suggested by third-year university student discovered 91 volcanoes in a massive region known as the West Antarctic Rift System. The volcanoes range in height from 100 m to 3 850 m (328 to 12 631 feet). A study conceived by a third-year student at the…

Huge Antarctic iceberg finally breaks free

Huge Antarctic iceberg finally breaks free

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…

Sea ice extent sinks to record lows at both poles

Sea ice extent sinks to record lows at both poles

Arctic sea ice appears to have reached on March 7 a record low wintertime maximum extent. This is the lowest maximum in the 38-year satellite record. On the opposite side of the planet, on March 3 sea ice around Antarctica hit its lowest extent ever recorded by…

NSIDC reports record low Arctic sea ice extent

NSIDC reports record low Arctic sea ice extent

Average Arctic sea ice extent for November set a record low, reflecting unusually high air temperatures, winds from the south, and a warm ocean, NSIDC reports. Since October, Arctic ice extent has been more than two standard deviations lower than the long-term…
