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 | The Nd isotopic compositions were measured by a Thermo Scientific Neptune-Plus® multicollector-inductively coupled plasma-mass spectrometer (MC-ICP-MS) at LDEO. The instrument was coupled with a desolvation introduction system (an Apex nebulizer). All measured Nd isotopic compositions were corrected for mass fractionation using an exponential law with ¹⁴⁶Nd/¹⁴⁴Nd = 0.7219. For each analytical session, standard JNdi-1 was measured between every sample. For each sample, the measured Nd isotopic composition is normalized to ¹⁴³Nd/¹⁴⁴NdJNdi = 0.512115 (Tanaka et al., 2000), using the average measured JNd sample of a measuring session. JNdi-1 standards yielded external reproducibilities (2σ) as follows: ± 0.30 εNd units for 50 ppb solutions, ± 0.32 for 40 ppb, ± 0.36 for 30 ppb, ± 0.33 for 20 ppb, and ± 0.42 for 10 ppb.
