Particulate geochemistry of sediment core POS536_73-1 (BC6)@en

This dataset consists of the results from particulate matter geochemical analyses of sediment cores that were taken during the cruise POS536 in August 2019. The research area was the North Atlantic gyre southwest of the Azores. 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 box corer and subsampled with MUC liners. MUC liner subsamples from three stations were sliced for geochemical analyses. Particulate organic carbon and nitrogen, total sulfur and CaCO3 contents of the solid phase were determined with an elemental analyzer.本数据集包含2019年8月POS536航次采集的沉积物岩芯的颗粒物地球化学分析结果。研究区域为亚速尔群岛西南海域的北大西洋环流区。本次航次为JPI Oceans项目HOTMIC采集了样品。HOTMIC项目的研究目标为探究微塑料颗粒从欧洲海岸向北大西洋环流区垃圾聚集区的分布与运移规律。沉积物样品采用箱式采泥器（box corer）采集，并通过MUC衬管（MUC liners）进行分样。对3个站位的MUC衬管分样进行切片处理以开展地球化学分析。采用元素分析仪（elemental analyzer）测定了固相中的颗粒有机碳、总氮、总硫以及碳酸钙（CaCO3）含量。
