Abstract |
The second phase of the deep ice core drilling at Dome Fuji, Antarctica is planned to be carried out in three successive summer seasons starting from 2003/2004 with an improved JARE deep ice core drill. On the basis of tests, major improvements were made including extension of the core barrel to 4m, addition of a more powerful chip-collecting pump, addition of a check valve to avoid loss of collected chips while hoisting the drill in borehole liquid, and a more powerful drill motor. This report describes the improvements and results of the tests as of December 2000. |
