Particulate geochemistry of sediment core POS536_66-1 (BC3)

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.
