First access to the ocean beneath Ekströmisen, Antarctica, by means of hot-water drilling

A hot-water drill developed during the past 2 years at Alfred Wegener Institute was used to penetrate the Ekstrom Ice Shelf several times near the Georg von Neumayer Station. The drilling operation was successful, and the initial large diameter (>35 cm) allowed easy access to the ocean. One hole...
