Auxiliary material for Radiocarbon profiles of the NW Pacific from the LGM and deglaciation: evaluating ventilation metrics and the effect of uncertain surface reservoir ages Mea S. Cook1* and Lloyd D. Keigwin2 1Geosciences Department, Williams College, 947 Main Street, Williamstown, MA 01267 2Geology & Geophysics Department, Mail Stop #8, Woods Hole Oceanographic Institution, Woods Hole, MA 02543 *corresponding author Paleoceanography Introduction: The auxiliary material includes an animation that shows the effect of the assumed surface reservoir age on radiocarbon calculations, tables of complised published planktonic-benthic radiocarbon data from the North Pacific,and a supplementary figure which is similar to Figure 8 in the main paper, but with additional radiocarbon data that have independent age control. The radiocarbon metrics are calculated as described in section 2.3 of the main paper. 1. Animation.gif This is an animated gif that is similar to Figure 5 in the paper, but where each frame shows the results for a different value of the assumed surface reservoir age. The DR value used in each frame is shown in the upper left corner. 2.

Supplemental figure.eps This figure is identical to Figure 8, except that radiocarbon data with independent estimates of surface reservoir age [Sarnthein et al., 2007; Ikehara et al., 2011] are plotted in red. We would need many more radiocarbon reconstructions with independent estimates of surface reservoir age in order to constrain how much of the scatter in the compilation is due to unaccounted-for changes in surface reservoir age.
