Concentrations and ratios were reduced assuming exponential fractionation. Calculated ratios were normalised to 146Nd/144Nd = 0.7219. The external precision for 143Nd/144Nd as judged from values for nNd-beta standard was 43 ppm. Accuracy correction was not necessary since the mean 143Nd/144Nd ratio was 0.511895±22 (n=20).60.7951123.413475.200582.5031Arctic Ocean
