The initial conceptual design of what is now called the Deep Ice Sheet Coring (DISC) Drill envisioned a drill capable of drilling a 3-meter core with ongoing design improvements leading to cores of greater length (Eustes et al., 2003). As the configuration of the drill was finalized during the design process (Shturmakov et al., 2007; Mason et al., 2007), the combined core barrel and screen (chip collection) section was set at approximately 11 meters. Based on the experience others had gained in operating other drills, the ratio of core length to length of chip collecting was calculated and the core length for the final configuration was estimated to be approximately 4 meters with the remaining 7 meters being needed for chip collection.
