Borehole optical televiewer (OPTV) logs of boreholes drilled into Khumbu Glacier, Nepal, in 2017 and 2018 as part of EverDrill research project

These are digital optical televiewer (OPTV) logs of four boreholes drilled by hot water to various depths (see Instrumented Borehole Info) in Khumbu Glacier, Nepal. Boreholes were drilled in May 2017 and 2018 to investigate the internal properties of Khumbu Glacier, specifically ice thickness, temperature, deformation and structure, as part of the NERC-funded 'EverDrill' research project.

Funding was provided by the NERC grant NE/P00265X/1 and NE/P002021/1.

本数据集为尼泊尔昆布冰川内4口经热水钻探至不同深度的钻孔的数字光学成像测井仪（digital optical televiewer, OPTV）测井日志，详见《仪器钻孔信息》（Instrumented Borehole Info）。上述钻孔于2017年5月与2018年5月完成钻探，作为由英国自然环境研究委员会（Natural Environment Research Council, NERC）资助的"EverDrill"研究项目的组成部分，旨在探究昆布冰川的内部特性，具体涵盖冰厚、温度、变形及结构特征。

本研究的资助经费来源于NERC的NE/P00265X/1号与NE/P002021/1号资助项目。
