The dataset consists of Nd isotopic ratios expressed in the epsilon notation (i.e. [((143Nd/144Nd)sw / (143Nd/144Nd)std) - 1]x10,000) measured in the Beaufort Sea at three stations sampled in 2009 (Aug 27 - Sep 12). 20L samples were collected and quickly filtered through an Acropak cartridge (0.45 um). The samples were then acidified to pH 2 with concentrated HCl and returned to the shore-based laboratory for analysis on a multi-collector Inductively Coupled Plasma mass spectrometer. The station locations are: L1 (71°06'N, 139°10'W, 12 samples at 12 depths), L2 (74°30'N, 137°00'W, 12 samples at 12 depths), and L1.1 (72°31'N, 136°48'W, 12 samples at 12 depths)
