The first leg of an ambitious, yearlong Arctic science expedition just ended, and scientists say they’ve already gained new insight into the rapidly changing Arctic—the fastest warming region on Earth.

An initial team of researchers from the MOSAiC Expedition—short for Multidisciplinary Drifting Observatory for the Study of Arctic Climate—arrived in the port city of Tromsø, Norway, on New Year’s Day after more than three months at sea. Billed as the largest Arctic science mission in history, the expedition launched from the same spot on Sept. 20, led by a German icebreaker known as the Polarstern.
