The scientists, who were taking part in NASA’s “Operation IceBridge,” were able to fly a follow-up mission above the Pine Island Glacierto gather unprecedented airborne measurements of an ongoing iceberg calving event. Typically, scientists can only learn of such events after they take place. READ MORE
