Over the course of the 2014/15 and 2015/16 austral summer seasons, the South Pole Ice Core project recovered a 1751 m deep ice core at the South Pole. This core provided a high-resolution record of paleoclimate conditions in East Antarctica during the Holocene and late Pleistocene. The drilling and core processing were completed using the new US Intermediate Depth Drill system, which was designed and built by the US Ice Drilling Program at the University of Wisconsin–Madison. In this paper, we present and discuss the setup, operation, and performance of the drill system.

南极冰芯 (SPICEcore) 项目的钻探作业

在 2014/15 和 2015/16 南方夏季期间，南极冰芯项目在南极恢复了 1751 米深的冰芯。该核心提供了全新世和晚更新世期间东南极洲古气候条件的高分辨率记录。钻探和岩芯处理是使用新的美国中深钻系统完成的，该系统由威斯康星大学麦迪逊分校的美国冰钻计划设计和建造。在本文中，我们介绍并讨论了钻孔系统的设置、操作和性能。
