Oldest Antarctic Ice: Will Searching For An Older Ice Core Help Understand Earth’s Climate?

Posted in climatology

Higgins and his team members collected an ice sample dated 2.6 million years ago from the Antarctic in the Allan Hills area. He claims it’s the oldest sample of ice with strong trust in the age and air within it. Through examining trace concentrations of argon gas contained within the frost, the sample was dated.

Experts hope to find the deepest ice cores drilled from the continent of Antarctica. They aim to gather samples that are as much as 1.5 million years old.
