Density measurements from a shallow ice core drilled at Summit, Greenland during June and July of 2024

The goal of this study was to measure in situ hydrogen gas (H2) and neon (Ne) levels in a shallow ice core drilled at Summit, Greenland in the summer of 2024.The Summit 2024 ice core was sited on a former dumping area for snow removed from Summit Station. In order to assess the depth of the disturbed snow layer, density was measured on full core sections. Upon recovery, the volume of the core section was calculated using a stainless-steel meter stick for the length and digital calipers for the diameter. The mass was determined using a top loading balance. H2 and Ne measurements from this study are published separately. This dataset contains 1) Density measurements

本研究旨在对2024年夏季在格陵兰岛萨米特（Summit）钻取的浅层冰芯内的原位氢气（H₂）与氖气（Ne）含量进行测定。本次钻取的萨米特2024冰芯布设点位曾为萨米特站（Summit Station）移除积雪的临时堆放区域。为评估受扰动积雪层的深度，研究人员对完整冰芯段开展了密度测量。冰芯回收后，采用不锈钢米尺测量长度、数显卡尺测量直径以计算该冰芯段的体积；其质量通过顶载天平测定。本研究测得的氢气与氖气相关数据已另行发表。本数据集包含以下内容：1）密度测量数据
