Raw physical properties measured on sediment core PS128_42-1@en

Sound knowledge about the petrophysical characteristics of a sediment core is a prerequisite for any subsequent paleoenvironmental study relying on sediment proxies. Physical properties of whole-round sediment cores are acquired as a first step of sediment core description, prior to slicing of sediment cores into two halves. Here, we present raw physical-properties data of core PS128_42-1 acquired with a Geotek MSCL-S system on the unsplit core, retrieved during RV Polarstern expedition PS128 \"EASI-1\" from Nielsen Basin, Antarctica, in austral summer 2022.对于任何依托沉积物代用指标开展的后续古环境研究而言，掌握沉积物岩芯的岩石物理特征是一项必要前提。在将沉积物岩芯切割为两半之前，整根沉积物岩芯的物理属性测量是沉积物岩芯描述的首要步骤。本数据集提供了岩芯PS128_42-1的原始物理属性数据，该数据由Geotek MSCL-S系统在未切割的完整岩芯上采集所得。岩芯PS128_42-1采自南极洲尼尔森盆地，于2022年南半球夏季由"极星号"（RV Polarstern）科考航次PS128 "EASI-1" 回收获取。
