Global sea-level rise and the disappearance of tidal notches

Coastal notches: Their morphology, formation, and function

“…The black dots and accompanying numbers and ages within the graphs refer to notch collapse events. Runs g) to j) are for rising RSL by Pirazzoli (1986b) and runs k) to n) for falling RSL by Evelpidou et al (2011aEvelpidou et al ( , 2012a, as shown in each case by the diagrams and arrows accompanying each notch profile, with the two dashed lines representing the high (upper line) and low (lower line) tidal levels. The classification is essentially non-genetic, in accordance with the principle of equifinality that suggests that similar notch forms, and associated rock coast features (shore platforms, cliffs, etc), can be produced by different combinations of processes.…”

“…Isostatic or eustatic changes in RSL are also responsible for the absence of notches in many tectonically stable areas along the Italian coast (Kershaw and Antonioli, 2004). The rate of present sea level rise may account for the gradual destruction or present lack of development of notches in the Mediterranean (Evelpidou et al, 2012a;Pirazzoli and Evelpidou, 2013). Therefore, because of changes in RSL and other mechanisms which can prevent notches…”

Impact of Holocene tsunamis detected in lagoonal environments on Corfu (Ionian Islands, Greece): Geomorphological, sedimentary and microfaunal evidence

“…These events clearly demonstrate the high neotectonic activity in the area of Corfu during historical times. Abrupt sea level changes associated to (pre-)historical earthquakes are also known for adjacent areas in northwestern Greece (Besonen et al, 2003;V€ ott et al, 2011a) and the coasts of the Adriatic Sea (Mathers et al, 1999;Antonioli et al, 2007Antonioli et al, , 2009Fouache et al, 2010;Faivre et al, 2011;Evelpidou et al, 2012). Based on geophysical and sedimentological investigations of submarine slopes and depressions offshore western Corfu, Poulos et al (1999) describe numerous seismically induced mass movements.…”

Abrasive notches along the Atlantic Patagonian coast and their potential use as sea level markers: the case of Puerto Deseado (Santa Cruz, Argentina)

“…In fact, notch shape and its relationship with sea level is strictly linked to the predominant genetic process. Tidal notches formed in carbonatic rocks, by bioerosion and carbonate dissolution, are widely used and considered one of the best mean sea level indicators (Pirazzoli, 1986;Rust and Kershaw, 2000;Kershaw and Guo, 2001;Lambeck et al, 2004;Kelletat, 2005;Evelpidou et al, 2012;Moses, 2013). Even if the debate on their genesis is still open (Moses, 2013), in microtidal area such as the Mediterranean Sea, the elevation of the retreat point (i.e.…”
