How on Earth do climate scientists study climate data from long ago? They dig and extract ice cores from frozen environments. Here, engineers describe the operation of the Blue Ice Drill during its initial test. This video showcases a double barrel coring design with glimpses of its action, normally hidden beneath the ice’s surface. The U.S. Ice Drilling Program plans and coordinates for the ice drilling science and technology communities, and provides drilling technology and operational support that enables the community to advance the frontiers of climate and environmental science.
