Baseline bulk sediment composition for sediment core SO268/1_74-1 (MUC-17) during RV SONNE cruise SO268 in the CCZ, Pacific Ocean

This baseline dataset comprises downcore measurements of the bulk sediment composition for a sediment core (MUC) retrieved in the framework of the European collaborative JPI Oceans MiningImpact project onboard R/V SONNE cruise SO268 in 2019. The scientific work during cruise SO268 was part of the second phase of the MiningImpact project (Environmental impacts and risks of deep-sea mining) and is designed to assess the environmental impacts of deep-sea mining of polymetallic nodules in the Clarion-Clipperton Zone (CCZ) in the Pacific Ocean. After performing total acid digestions, the sediments were analyzed using ICP-AES (iCAP 7400, Thermo Scientific) at the Marine Geochemistry Lab, Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, Bremerhaven.

本基准数据集包含了2019年R/V SONNE远洋考察船SO268航次中，在欧洲合作JPI Oceans MiningImpact项目的框架下，采集的沉积岩心（MUC）的总体沉积物组成下钻测量数据。在SO268航次的科学研究中，本工作属于MiningImpact项目第二阶段（深海采矿的环境影响与风险）的一部分，旨在评估太平洋克拉里永-克利珀顿海盆（CCZ）多金属结核深海采矿的环境影响。经总酸消化处理后，沉积物在阿尔弗雷德·魏格纳研究所海洋地球化学实验室（Thermo Scientific iCAP 7400 ICP-AES）进行分析。
