The file contains the validation data on certified reference material for Nd isotope measurement, the LA-MC-ICP-MS composite Pb isotope ratios and Nd isotope time series for Tropic Seamount, north-east Atlantic Ocean. The dataset spans a deposition history covering the last 75 Ma. The record was obtained by analysis of hydrogenetic ferromanganese crust samples recovered during the 2016 JC142 expedition of the MarineE-Tech project.
This dataset contains the low-resolution isotopic data (O & C) covering the last 1Ma, which is used to establish a more precise glacial-interglacial stratigraphy than the shipboard bio/paleomagneto stratigraphy for 2 NW Pacific Sites (IODP EXP350 1436C and 1437B) both were recovered at intermediate depths. The planktonic foraminifera census counts are used to assess the changes in surface water in the area affected by the Kuroshio Current. They are also used in concert with other sedimentological, micropaleontological or taphonomical evidences to estimate the changes in carbonate preservation at intermediate water depth in relation to changes in global ocean circulation during glacial interglacial cycles.
