Abstract

The Port Miou system (Cassis, France) is a long submarine gallery developped in the limestone series of Calanques (Marseille, France). Its speleological exploration suggests a deep karstic system higly polluted by seawater. The strong geochemical signature of the titanium in the surface sediment supports the model of a sea water aspiration in a deep gallery connected to the Cassidaigne canyon. This speleological model of sea aspiration explains why all the attempts to diminish the salinity of the brackish spring by construction of a dam have failed
