| Neodymium isotopic composition and rare earth element concentrations were measured in seawater samples from eleven stations in the Nordic Seas. These data allow us to study how the Iceland Scotland Overflow Water ( ISOW) acquires its neodymium signature in the modern ocean. The waters overflowing the Faroe Shetland channel are characterized by epsilon(Nd) = -8.2 +/- 0.6, in good agreement with the only other data point, published 19 years ago. In the Greenland and Iceland Seas the water masses leading to the formation of the ISOW display lower neodymium isotopic composition, with epsilon(Nd) around -11 and -9, respectively. Since no water masses in the Nordic Seas are characterized by epsilon(Nd) > -8, the radiogenic signature of the ISOW likely... |
