At the northern and southern tips of our planet are tiny bubbles of air trapped for millions of years within polar ice. These microscopic time capsules hold a record of Earth’s atmosphere — and thus its climate history. (Higgins, Shackleton, Bender mention)

On December 12, 2023, the International Ocean Discovery Program (IODP) Expedition 401 departed from Amsterdam to begin a two-month scientific journey to the Gibraltar Strait. Its mission is to uncover these climate secrets buried beneath hundreds of meters of water and rock. Onboard will be Harry Hess postdoctoral research fellow and paleoclimate scientist Udara Amarathunga.
