Paleo Slide Set: Polar Ice Cores
Core barrel being removed from drill
The drill assembly is lowered into the borehole on a heavy cable. Using electric power, the drill extracts a 6 m long section of ice. The core is then carefully raised to the surface. The newly-filled core barrel in this photo is gingerly being removed from the drill apparatus. Once the barrel is removed from the drill apparatus, it is replaced with another core barrel. The drill is then lowered into the borehole for another coring run.
