Short summary
An extensive compilation of published neodymium (Nd) concentrations and isotopic compositions (Nd IC) was realized in order to establish a new database and a map (using a high-resolution geological map of the area) of the distribution of these parameters for all the Mediterranean margins. The use of a high-resolution regional oceanic model (1/12° of horizontal resolution) allows us to realistically simulate for the first time the Nd IC distribution in the Mediterranean Sea.
