Sample ages are interpolated according to the age model based on Be-stratigraphy of core PS1533 sediments (Eisenhauer et al., 1994, doi:10.1016/0012-821X(94)00069-7). In-run uncertainties given for Sr and Nd isotope ratios are 2 sigma errors. Sr and Nd concentrations were measured by isotope dilution, Rb was measured by XRF. D= duplicates, which are complete chemical and mass spectrometric procedures on different sample aliquots. Epsilon-Nd values are calculated as epsilon-Nd = [[143Nd/144Nd_sample/143Nd/144Nd_CHUR] - 1] x 10**-4 using the present-day CHUR value 143Nd/144Nd_CHUR = 0.512638 (Jacobsen and Wasserburg, 1980).
