Title

Neogene neodymium isotope data from the Philippine Sea (IODP Expedition 351) (NERC Grant NE/M017370/1)

Abstract

We report sedimentary coatings and fish teeth neodymium isotope values – tracers for water-mass mixing – from deep-water International Ocean Discovery Program (IODP) Site U1438 (4.7 km water depth) in the Philippine Sea, northwest Pacific Ocean. The time period encompasses the last 20 million years.

We reconstructed past water-mass signatures at Site U1438 by measuring åNd of fossil fish teeth and ferromanganese oxyhydroxide coatings, which record the isotopic value of bottom water at the sediment surface. After process, the samples were digested in concentrated HNO3 overnight and then placed in 2N HNO3 for column chemistry, and analyzed on a Thermo Scientific Triton thermal ionization mass spectrometer as Nd+. Full methods are available in Kender et al. (2018) (citation provided within the data file).
