Stratigraphic evidence from study sites. (a) Tofino pit lithology (see Fig. 1b for location) and chronology. Details of radiocarbon ages are given in Supplementary Table S1. Numerical superscripts following radiocarbon ages correspond to the sample numbers in Fig. 3 and Table S1. (b) Stratigraphic cross-section along transect X-X’ in Ucluelet (see Fig. 1c for location) showing radiocarbon ages (Supplementary Table S1) and vertical distribution of 137Cs. Numerical superscripts following radiocarbon ages correspond to the sample numbers in Fig. 3 and Table S1. (c) Photograph of Ucluelet pit wall. (d) Relative abundance of selected brackish-marine diatom species from the Ucluelet pit. Gray bars indicate assemblages within sand sheets UC1–4 (full diatom assemblage in Supplementary Fig. S1). (e) Stratigraphic cross-section along transect Y-Y’ in Port Alberni (see Fig. 1d for location) showing radiocarbon ages (Supplementary Table S1). Numerical superscripts following radiocarbon ages correspond to the sample numbers in Fig. 3 and Table S1.
