Like most of the world’s coastlines, the Korean Peninsula experienced higher-than-present sea levels during the Last Interglacial (LIG), otherwise known as Marine Isotope Stage (MIS) 5e. However, the expression of that highstand in the geologic recordsea levels differs across the eastern and western Korean Peninsula. The tectonically active east coast of the Korean Peninsula is characterized by broad uplifted marine terraces, while the stable west coast is characterized by tidal flats and rias. In this study, we used a standardized database template to review and extract the existing constraints on LIG sea levels along both the east and west coasts of the Korean Peninsula. A total of 62 LIG constraining data points were compiled, including 34 sea-level indicators, 22 marine limiting records, and 6 terrestrial limiting records. The ages from these data points are based on 61 optically stimulated luminescence (OSL) measurements and 1 paleomagnetic-based age.
