Abstract:
Authigenic neodymium isotopes measured on bulk sediment leachates and mixed planktic foraminifera from deep-sea sediment cores from the Nordic Seas and Arctic Ocean dated from the last glacial to modern. Data was used to reconstruct past changes in ocean circulation in this region. Neodymium isotope data was collected on a Thermo Fischer Neptune Plus Multicollector Inductively Coupled Plasma Mass Spectrometer (MC-ICP-MS).
