Over the next several years, a group of U.S. researchers will drill a deep ice core from Hercules Dome, Antarctica to help provide fundamental information about Earth’s climate and to learn more about West Antarctica’s past—and future—contribution to global sea level rise. The Hercules Dome ice core provides an opportunity to make progress on a number of science priorities, including understanding the environmental conditions of the last interglacial period, the history of gases and aero
