Endangered glaciers: Alpine ice begins Antarctic voyage – BBC News

By Victoria Gill Science reporter, BBC News

first step in their journey to Antarctica.

The seemingly strange plan to send ice to the coldest place on Earth is part of a scientific mission to “rescue” some of the world’s most endangered glacial ice.

Bubbles in old, deep glacial ice are frozen records of our past atmosphere.

Scientists say their purpose-built Antarctic ice bunker will keep these safe for future research.

“What we know for sure is that the ice will not be here in 50 or 100 years time – any glacier below 3,500m altitude will be gone by the end of the century,” explained Jerome Chappellaz from France’s National Centre for Scientific Research, one of the leaders of the project.

“[In the Alps], we’re trying to recover ice cores from one of the glaciers that is in danger.”

That glacier is at Col du Dome – just below the peak of Mont Blanc. It is one of two that the team has chosen to provide their frozen library with “reference ice” for regions where information on past climate and atmosphere is lacking.

The team set up a high altitude research camp on the ice while they worked. They have now successfully extracted three full ice cores, drilling their cylindrical cutting device through the entire 130m depth of the glacier.
