Simulating marine neodymium isotope distributions using Nd v1.0 coupled to the ocean component of the FAMOUS–MOSES1 climate model: sensitivities to reversible scavenging efficiency and benthic source distributions
Abstract:Abstract. The neodymium (Nd) isotopic composition of seawater is a
widely used ocean circulation tracer. However, uncertainty in quantifying
the global ocean Nd budget, particularly constraining elusive
non-conservative processes, remains a major challenge. A substantial
increase in modern seawater Nd measurements from the GEOTRACES programme,
coupled with recent hypotheses that a seafloor-wide benthic Nd flux to the
ocean may govern global Nd isotope distributions (εNd),
presents an opportunity to develop a n… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
