日本第二个深冰取芯项目在南极洲的Dome Fuji进行。继2001年钻取导孔之后，日本南极研究考察队（JARE）领导的深冰芯钻探从2003/04季节开始，在南极四个夏季进行，并于2007年1月达到基岩附近3 035.22米的深度。设计和开发新钻头的目的是（1）解决第一台JARE深取芯钻头遇到的问题，（2）实现更高效的钻探。特别是，一次可钻取的最大岩心长度从2.30 m增加到3.84 m，并通过具有许多小孔的特殊管道提高了碎屑存储效率。本文概述了改进后的钻井系统、钻井进展情况和各项钻井数据。
The Japanese second deep ice coring project was carried out at Dome Fuji, Antarctica. Following the drilling of the pilot hole in 2001, deep ice core drilling led by the Japanese Antarctic Research Expedition (JARE) was conducted over four austral summer seasons, beginning with the 2003/04 season and reached a depth of 3035.22 m near the bedrock in January 2007. The new drill was designed and developed with the goals of (1) solving the problems encountered during the first JARE deep coring drill and (2) achieving more efficient drilling. In particular, the maximum core length that can be drilled at one time was increased from 2.30 m to 3.84 m and the chip storage efficiency was enhanced by a special pipe with many small holes. This paper gives an outline of the improved drilling system, the progress of drilling and various drilling data.
