摘要2014年至2016年期间，使用新设计的美国中间深度钻在南极钻取了中间深度（1751 m）的冰芯。南极冰芯是最高分辨率的南极东部冰芯记录，延伸到冰期。描述了在南极处理和记录钻冰的方法、将冰安全逆行返回国家科学基金会冰芯设施（NSF-ICF）的程序以及在NSF-ICF处理和取样冰的方法。ICF。南极冰芯显示出最小的脆性冰，这可能是由于现场的特点，并在较小程度上，钻井技术和核心处理程序。
Abstract An intermediate-depth (1751 m) ice core was drilled at the South Pole between 2014 and 2016 using the newly designed US Intermediate Depth Drill. The South Pole ice core is the highest-resolution interior East Antarctic ice core record that extends into the glacial period. The methods used at the South Pole to handle and log the drilled ice, the procedures used to safely retrograde the ice back to the National Science Foundation Ice Core Facility (NSF-ICF), and the methods used to process and sample the ice at the NSF-ICF are described. The South Pole ice core exhibited minimal brittle ice, which was likely due to site characteristics and, to a lesser extent, to drill technology and core handling procedures.
