Pore water geochemistry of sediment core GeoB24346-2@en

The samples are retrieved from sediment core GeoB24346-2 (Milano MV; 0-274 cm) in the Olimpi mud volcano field, located south of Crete at the Mediterranean Ridge accretionary complex. Major and minor element concentrations were measured at MARUM by ICP-OES and Metrohm ion chromatography and on selected samples. On board, 5 to 10 ml of pore water were extracted from the splitted cores every 5 to 20 cm during using rhizon samplers. Cations (B; Ba; Ca; Fe; K; Li; Mg; Mn; Na; S; Si; Sr) were measured by ICP-OES (Agilent 710 Simultan with a precision of 1%) and anions (F; Cl; Br; SO4) were measured by Metrohm ion chromatography with a precision of <1%.本数据集的样本采自位于克里特岛以南地中海脊增生杂岩带的奥林匹泥火山场中的沉积物岩芯GeoB24346-2（Milano MV；0~274 cm）。科考过程中，在船上采用里奇恩采样器（rhizon samplers）对拆分后的岩芯按每5~20 cm的间隔提取5~10 mL孔隙水。针对选定样本的主量与微量元素浓度，于不来梅海洋环境研究中心（MARUM）进行测定：其中阳离子（B、Ba、Ca、Fe、K、Li、Mg、Mn、Na、S、Si、Sr）采用安捷伦710型同步电感耦合等离子体发射光谱仪（ICP-OES，Agilent 710 Simultan）测定，测定精度为1%；阴离子（F、Cl、Br、SO4）则采用万通（Metrohm）离子色谱法测定，测定精度小于1%。
