Submarint grundvattensutflöde
Ett submarint grundvattensutflöde är ett område under havsnivån där grundvatten blandas ut med havsvattnet. Ett submarint grundvattensutflöde sker där en akvifer angränsar till ett havet. Vid Submarina grundvattensutflöden sker en hel del kemiska reaktioner på grund av blandning av vatten med olika temperaturer, salthalt och övrig kemi.[1] Submarina grundvattensutflöden tillför viktiga ämnen för marint liv.[1] Forskning visar att vid vissa passiva kontinentränder drivs det submarint grundvattensutflödet av geotermal värme from djupa områden i jordskorpan.[1]

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.
