Drilling Overdeepened Alpine Valleys (DOVE) - Operational Dataset of DOVE Phase 1

The overarching goal of the Drilling Overdeepened Alpine Valleys (DOVE) project will be to date the age and extent of past glaciations. Formerly-glaciated areas are often characterized by deeply incised structures, often filled by Quaternary deposits. These buried troughs and valleys were formed by glacial overdeepening, likely caused by pressurized subglacial meltwater below warm-based glaciers. Results of this drilling campaign, supported by new dating technologies, will further provide critical data on 'how' and 'at which rate' glacial erosion affects such mountain ranges and their foreland. These processes are also of fundamental importance for evaluating the safety of radioactive waste disposal sites, which are planned in areas of former glaciations. Moreover, results of this project will fill gaps in the knowledge of paleoclimate and atmospheric circulation patterns during past glacial epochs and how these patterns affected ice build-up. The operational data sets include the drill core documentation from the mobile Drilling Information System (mDIS), full round core scans, MSCL data sets, a preliminary core description and the geophysical downhole logging data that were acquired during and subsequent to the drilling operations. All downhole logs and core depth were subject to depth correction to a common depth master (cf. operational report for detailed information). The data are described by two scientific reports, the Operational Report (https://doi.org/10.48440/ICDP.5068.001) and the Explanatory Remarks on the Operational Datasets (https://doi.org/10.48440/ICDP.5068.002).

阿尔卑斯超深钻谷（Drilling Overdeepened Alpine Valleys, DOVE）项目的总体目标，是确定过去冰川作用的年代与分布范围。古冰川作用区域常以深切构造为典型特征，此类构造多被第四纪沉积物充填。这些被掩埋的槽谷与谷地由冰川超深侵蚀作用形成，其成因大概率与暖基冰川下方的承压冰下融水有关。本次钻探计划依托新型定年技术所获成果，将进一步提供关于冰川侵蚀“以何种方式”以及“以何种速率”作用于此类山脉及其前陆的关键数据。此类过程对于评估拟建于古冰川区域的放射性废物处置库的安全性，同样具有核心意义。此外，本项目成果将填补古气候与过去冰川时期大气环流模式相关认知的空白，以及此类模式如何影响冰体积累的相关认知空白。本作业数据集涵盖：移动式钻探信息系统（mobile Drilling Information System, mDIS）生成的岩心记录、完整岩心轮扫数据、MSCL数据集、初步岩心描述，以及钻探作业期间及后续获取的地球物理井下测井数据。所有井下测井数据与岩心深度均已统一校正至共同深度基准（详细信息请参阅作业报告）。本数据集由两份科学报告进行说明：《作业报告》（https://doi.org/10.48440/ICDP.5068.001）与《作业数据集说明》（https://doi.org/10.48440/ICDP.5068.002）。
