Dissolved neodymium (Nd) isotopes and concentrations of rare-earth elements (REEs) reported by LDEO in seawater samples collected during the GEOTRACES GP16 East Pacific Zonal Transect cruise (TN303) on R/V Thomas G. Thompson from October to December 2013

This dataset includes dissolved neodymium (Nd) isotopes and concentrations of rare earth elements (REEs) in seawater samples collected along the GEOTRACES GP16 East Pacific Zonal Transect. The cruise was aboard the R/V Thomas G. Thompson between October 25 and December 20, 2013 from Manta, Ecuador to Papeete, Tahiti. Multicollector-inductively coupled plasma-mass spectrometry (MC-ICP-MS) was used to analyze Nd isotopes and quadrupole ICP‐MS was used to analyze REE concentrations.

This cruise provides a great opportunity to understand sources, sinks, and cycling of REEs in the ocean as well as how well Nd isotopes behave as a conservative water mass tracer. The data were collected by Yingzhe Wu and Chandranath Basak at Lamont-Doherty Earth Observatory of Columbia University.
