Sedimentary sequences along continental and insular margins serve as archives of coastal erosion by storms and tsunamis. In areas where overwash is limited or precluded by barrier width and height, such as prograded beach-ridge plains (strandplains), geomorphological (scarps) and lithological (heavy-mineral concentrations) indicators provide the only means of assessing the extent and timing of erosional events. This research presents geological evidence of buried erosional scarps along the Black Sea coast of southwestern Ukraine. A distinct paleo-scarp imaged in shore-normal georadar profile and the associated heavy-mineral horizon (magnetic susceptibility >1,700 SI) indicate a storm event that impacted the shoreline of Sasyk Liman baymouth barrier inhistorical times. Optical dating offers a more reliable chronology of erosional events, whereas radiocarbon-dated reworked early Holocene shells aid in determining the sources of bioclastic material.
