Intermediate-depth ice coring of high-altitude and polar glaciers with a lightweight drilling system
International audience A total of 11 ice cores to a maximum depth of 460 m have been obtained over the past 3 years from high-altitude glaciers on the saddle of Mount Bona and Mount Churchill in Alaska (designated B-C), and on Quelccaya ice cap and Nevado Coropuna in Peru. Ice coring was conducted u...
