Ancient ice from Antarctica, extracted as part of the Oldest Ice Project, has been slowly melted at the British Antarctic Survey in Cambridge.

The ice cores, cylindrical tubes of old ice, are expected to reveal a climate record stretching back more than 1.5 million years.

Zelna Weich, a PhD candidate at the British Antarctic Survey, talks Louise Hulland through the process.
