Abstract :Bodrum Peninsula, which developed under the influence of the extensional tectonic regime in the west of the Anatolian plate, is one of the areas where indicators reflecting relative sea-level changes are seen above the present sea level. These indicators appear in different types throughout the peninsula. This study examined shorelines from sea level to +2.6 m at 6 locations on the southern coast of the Bodrum Peninsula. Suitable indicators for dating were found at two different locations in the study area, and two relative sea-level indicators using mollusk shells were dated by radiocarbon method. One of the indicators is a +1.3 m high beach deposit at Gerenkuyu and was dated to 2678.5±79.5 yr BP. The other indicator is a +1.2 m high beach deposit at Gerindere, which is thought to be compatible with the tidal notch and dated to 2241±88 yr BP. Based on the age data and the reliability of tidal notches as a shoreline indicator, the uplift rate of this indicator in Gerindere for the last 2241±88 years has been calculated to be 0.53 mm/yr.
