Seabed Classification map of Ag. Kyriaki (a), Paleochori-Thiorychia (b) and Vani (c) herein referred as Cluster A, B and C respectively including inset histograms depicting the correlation between gas flares and seabed classification (D: Depression, R:Ridge, F:Flat area). Correlation between gas expulsion and seabed geomorphology was conducted by associating gas release locations with specific morphological features identified through the seabed classification scheme, namely depressions, ridges, and flat areas. The analysis reveals that the majority of gas flares occur in flat areas, followed by depressions.
