Finding Out How Fast Greenland Is Melting

In the spring of 2016, Erich Osterberg, a professor of earth sciences, led a scientific expedition to Greenland. For five weeks, he and his team traveled across the ice sheet taking measurements and obtaining ice cores that were sent to Dartmouth for further study. Osterberg and graduate students he works with talk about what they found, what it’s like to live on an ice sheet, and how their work can help society better understand—and prepare for—climate change.
