| Resumo |
High resolution seismic profiles of the Alicante continental shelf have been studied identifying a seismic prism which top at about -20 m below today sea-level. The prism is covered by recent sediments and can be interpreted as formed during a short interval of stand-by in the general transgression after the last glacial maximum. The -20 m level have been compared with the holocene Mediterranean sea-level-curve to propose an age of about 8 ka BP coinciding with the «8.2 ka cooling event» that was an abrupt, widespread climate instability. The prism top is deeper in the northern seismic profiles thus indicating a more subsidence that the southern coastal shelf where an erosion surface with rocky shoals configure the sea bottom.
