Porewater geochemistry of sediment core AL534/2_60-7 (MIC43)@en

This dataset consists of the results from pore water geochemical analyses of sediment cores that were taken during the cruise AL534/2 in March 2020. The research areas were the coastal waters close to major river mounds off the coasts of Spain, Portugal, Belgium, Great Britain, the Netherlands and Germany. During this cruise, samples were collected for the JPI Oceans project HOTMIC. The research objective of HOTMIC is the investigation of distribution and transport of microplastic particles from the European coast to the garbage accumulations in the North Atlantic gyre. Sediment samples were taken with a mini multi corer and, in one case, with a mini box corer. Pore water from sliced cores was extracted with rhizones. Geochemical analyses include the quantification of major anions and cations using inductively coupled plasma atomic emission spectroscopy and ion chromatography, respectively.本数据集包含2020年3月AL534/2航次采集的沉积物岩芯孔隙水地球化学分析结果。本次航次的研究区域为西班牙、葡萄牙、比利时、英国、荷兰及德国沿岸邻近大型河流沉积丘的近岸海域，所采集样品服务于JPI Oceans项目HOTMIC。HOTMIC项目的研究目标为探究微塑料颗粒从欧洲沿岸向北大西洋环流垃圾聚集区的分布与运移规律。沉积物样品采用微型多管采样器（mini multi corer）采集，仅1个站位采用微型箱式采样器（mini box corer）获取；经切割分样的岩芯孔隙水通过根状渗析器（rhizones）提取。地球化学分析涵盖分别采用电感耦合等离子体原子发射光谱法（inductively coupled plasma atomic emission spectroscopy）与离子色谱法（ion chromatography）对主要阴、阳离子进行定量检测。
