Holocene submerged shorelines on Theologos area (Greece)

Global sea-level rise and the disappearance of tidal notches

“…In contrast, greater submergence would imply a tectonic effect, such as that observed at Ios and Amorgos. The occurrence of recent co-seismic subsidence appears to have caused local submergences of tidal notches up to half a meter (including the effects of the recent global sea-level rise) at several sites of the northern coast of the gulf of Corinth (Evelpidou et al, 2011b), although such effects could not be detected at other sites of the same area, because fresh water from coastal springs tends to influence erosion and coastal geomorphology.…”

“…: Desruelles et al, 2004) and by submerged tidal notches (e.g. : Evelpidou et al, 2011b) suggest that periods of relative sea-level stability may have alternated with events of rapid subsidence, while evidence of emergence seems missing from the Cycladic islands.…”

“…In this case, a visor will be formed just above the water surface ( Fig. 2f′), which should not be confused with a tidal notch (Evelpidou et al, 2011b).…”

“…4b) facing the small Ampelos Island (northern coast of Corinth Gulf). In the lower part of the visor profile, the base of a tidal notch is missing and no other submerged notch can be observed below the visor, suggesting that no recent co-seismic events affected this area (Evelpidou et al, 2011b), or that the effects of freshwater outflow prevented the formation of reliable sea-level indicators. Local spring tidal range is 20 cm.…”

Numerical modeling of tidal notch sequences on rocky coasts of the Mediterranean Basin

“…Tidal notches are a generally accepted sea level marker [e.g., Pirazzoli et al , , , ; Laborel et al , ; Kershaw and Guo , ; Evelpidou et al , , b, , ; Boulton and Stewart , ; Antonioli et al , ]. Ongoing horizontal erosion of chemical, physical, and biological agents [e.g., Furlani et al , ; Antonioli et al , ; Evelpidou and Pirazzoli , ] contributes to notch formation at mean sea level.…”
