Neodymium isotopic composition of the oceans: A compilation of seawater data
International audience A global compilation of the neodymium isotopic composition of seawater is presented. With 880 data points, it confirms the gradual εNd increase for intermediate/deep water masses from the northwest North Atlantic, via the Austral and Indian oceans, to the Pacific. This confirm...
