Details of the study site and GPR transects. (a) Aerial photograph (CHO-78–07-06B-0012, taken by Geospatial Information Authority of Japan) of the area outlined in Fig. 1b showing core locations and GPR transects. (b) DSM obtained in this study, with elevation range restricted to display surface features of the beach ridge. (c) Annotated GPR images along the transects shown in (a). The four GPR facies identified in this study are differentiated by color. Vertical exaggeration is approximately 4 × . The original GPR images are displayed in Supplementary Fig. S3.
