Continuous inflow of seawater and outflow of brackish water in the substratum of the karstic island of Cephalonia, Greece

There is massive, continuous inflow of seawater at a place on the coast of the karstic island of Cephalonia in the Mediterranean. This current reappears at the coast on the other side of the island. this is extremely astonishing when it is considered that for water sea level represents minimum potential in the earth's gravitational field. The nature of the energy which causes the phenomenon has been the subject of numerous as yet unconfirmed hypotheses on the part of numerous authors. This study proposes a new explanation connected with the existence of a marine current which creates a hydraulic gradient between the two sides of the island but with inflow being maintained by density flow. This is made possible by a deep karstic conduit created during the Cenozoic period and which runs in the same direction as the marine current.
