Another fiasco in Antarctica: $12M ice drilling project fails when hose freezes and fossil fuel runs short
Polar drilling problems revealed : Nature News & Comment: "A specially developed hot-water drilling technique, devised by engineers at the British Antarctic Survey, was designed to minimize air and water pollution...Water also leaked into the cavity drill and froze the hose in the drill hole. Attempts to remove the hose failed, so it had to be cut. At that point, and with not enough fuel left to reach the lake, Siegert gave up."
