'Colder and deeper’: Scientists close in on spot to drill Antarctic ice core 1.5m years old

Australian Antarctic Division will drill 3,000 metres deep in bid to improve ancient climate records and future models

Antarctic scientists are close to finalising a drilling location deep in the frozen continent's interior that could reveal a continuous record of the Earth's climate going back 1.5 million years.

After almost a decade of work, scientists at the Australian Antarctic Division are close to pinpointing a place to drill an ice core almost 3,000-metres deep.
