Beskrivning:

Submarine karst spring (“Vrulja”) at the coast of Croatia, north of Brela. As the hydraulic head seems to be strong, the intrusion uprising of the karst conduit’s freshwater is well visible. Depending on more or less intrusion at the outlet, there is Chloride intrusion – at least by tectonic fissures in karstic rocks, which - inevitably -remain in contact with sea water.
The Adriatic Sea is flanked by the karstic Dinaric Alps. This is why there are numerous submarine springs along the coastline from Slovenia to Albania. Since late Pleistocene the water table of the Adriatic Sea rose by ca. 120 m. Springs that emerged on the surface became submarine.
