Integrated terrestrial and submarine geomorphological mapping provides insights into the Quaternary landscape evolution of the Gulf of Corinth, Greece

This study presents a 1:150,000 scale geomorphological map of the Gulf of Corinth (central Greece), integrating terrestrial and submarine landforms. The Gulf, an asymmetric WNW-ESE half-graben, is one of the tectonically most active areas in the eastern Mediterranean, with an uplifting southern flank and a downward flexed northern one. A multidisciplinary approach, combining field surveys and high-resolution seafloor bathymetry, was used to map the emerged and submerged geological and geomorphological features. The southern terrestrial sector shows clear evidence of tectonic uplift, such as marine terraces, elevated Gilbert deltas, tidal notches at higher elevations, and reversed drainage features. In contrast, the northern part is notable for the absence of Quaternary marine or lacustrine sediments and displays a gently sloping shelf with submerged tidal notches, indicating ongoing tectonic subsidence. The map offers a comprehensive view of the complex geomorphology of the region, shaped by Quaternary tectonic activity.
