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

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.
