Antarctica’s next deep ice core, drilling down to ice from 130,000 years ago, will be carried out by a multi-institutional U.S. team at Hercules Dome, a location hundreds of miles from today’s coastline and a promising site to provide key evidence about the possible last collapse of the West Antarctic Ice Sheet.

The roughly five-year, $3 million, NSF funded project involves the University of Washington, the University of New Hampshire, the University of California, Irvine and the University of Minnesota. Work has been delayed by the novel coronavirus, but drilling the 1.5-mile ice core likely will begin in 2024.

“The Hercules Dome ice core will be the first U.S. ice core with the potential to yield a detailed climate record during the last interglacial period,” said principal investigator Murat Aydin at the University of California, Irvine.
