Neodymium isotopes in seawater samples collected during the IN2017-V01 voyage of the RV Investigator
Progress Code: completed Statement: Multiple procedural blanks and certified standards were processed and analysed in the same manner as samples. Accuracy and precision of the seawater - Nd analysis were assessed using JNdi-1 isotopic reference material (Geological Survey of Japan, Tanaka et al., 20...
