A team of researchers affiliated with multiple institutions in the U.S. has successfully pulled an ice core from Antarctica’s Ong Valley that contains samples of Earth’s atmosphere from up to 5 million years ago. In their paper published in The Cryosphere, the researchers explain why they chose to drill in the Ong Valley and what they hope to learn from their study of the ice core.
