Porewater geochemistry of sediment core AL534/2_39-6 (MIC27)@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.本数据集涵盖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成果。研究区域为西班牙、葡萄牙、比利时、英国、荷兰与德国沿岸邻近大型入海河口沉积丘的近岸水域。本次航次为JPI海洋计划（JPI Oceans）下属的HOTMIC项目采集了样品。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内垃圾堆积区的分布与运移规律。沉积物样品采用小型多管采泥器采集，仅1份样品采用小型箱式采泥器采集。经切割分样的岩芯孔隙水通过根际渗滤管（rhizones）提取。地球化学分析内容包括分别采用电感耦合等离子体原子发射光谱（inductively coupled plasma atomic emission spectroscopy）与离子色谱（ion chromatography）对主要阴、阳离子进行定量检测。
