The response of the Peruvian Upwelling Ecosystem to centennial-scale global change during the last two millennia

SM 1. Cross correlation of laminated sequences among gravity cores (G) and box-cores (B). All the cores were retrieved off Pisco, Peru. The yellow lines indicate the position of the sedimentological shift (Gutierrez et al. 2009), the upper black bold lines indicate the start of Am activities and the green thick lines indicate the correlations of the diatomrich layers. The stratigraphic markers are represented by the continuous (dashed) colored thin lines that indicate possible (less obvious) correlations and represent the base of the sediment sequences (from A to K) except for the sections A and D where the base is 0 10 20 30 40 50 60 70 80 90 100 110 120 130 140 150 160 G-17
