Physical and bulk and authigenic geochemical and radiocarbon data of marine sediment cores from the deep Northeast Atlantic since the last glacial

The data comprise measurements of magnetic susceptibility and brightness (L*) for Site Me68-91 and Site Me68-89, water content data for Site Me68-89, and XRF elemental counting intensities for Site Me68-196. Furthermore, geochemical data were collected in the form of metal concentrations including r...

Description
Summary:The data comprise measurements of magnetic susceptibility and brightness (L*) for Site Me68-91 and Site Me68-89, water content data for Site Me68-89, and XRF elemental counting intensities for Site Me68-196. Furthermore, geochemical data were collected in the form of metal concentrations including rare earth elements (measured with ICP-QMS), carbonate contents, and neodymium isotope compositions (measured with MC-ICP-MS) in the authigenic sediment fraction extracted via weak sediment leaching and dissolution of picked foraminifera, and in the detrital sediment fraction. The data were interpreted in terms of sedimentology, rare earth element exchange between seawater and sediment, and past ocean circulation. Radiocarbon data (measured with MICADAS) from planktic foraminifera were measured for age model construction.
