A global compilation of the neodymium isotopic composition of seawater for GEOTRACES

GEOTRACES will allow the collection of numerous data that will be archived in the GEOTRACES Data Assembly Centre (GDAC), and will eventually contribute to create a world atlas of tracers in the ocean. However, data acquired on GEOTRACES core parameters in the framework of past cruises could also be considered in this gathering. With this aim, François Lacan and co-authors (Lacan at al, 2012) propose a commented compilation of the neodymium (Nd) isotope and concentration data published before September 1st, 2011. A very interesting tool for modellers and any other scientist following works on this tracer!
