Mayewski, Potocki talk with Eos about Everest ice core

Paul Mayewski and Mariusz Potocki are included in the Eos story “An Ice Core from the Roof of the World” about the 2019 National Geographic and Rolex Perpetual Planet Everest Expedition. Mayewski, director of the Climate Change Institute, was the expedition leader and lead scientist. Potocki, a Ph.D. candidate, collected the highest ice core in the world at 8,020 meters on South Col. “I really felt so lucky I was able to collect such a good-quality ice [core] at 8,000-meter elevation,” said Potocki. “Mission accomplished.” He and Mayewski have begun analyzing the sample using a nondestructive and high-resolution technique called laser ablation, according to the article. “We’ve found the things we hoped to so far,” Mayewski said. “The ice is well-preserved in terms of a climate and environmental record.”
