Submarine springs on the Bulgarian Black Sea coast

Abstract

Submarine springs have attracted people's attention from ancient times. Initially, the interest was directed to submarine groundwater known today as „submarine sources” and were commonly used for drinking and irrigation purposes. It has been found that fresh water from deep (Oligocene) faults has been found to be entering hydrocarbon gases known today as "submarine gas springs". The Black Sea is regarded as one of the most saturated areas with submarine springs and gas separating structures in the World. The article examines the status of submarine springs along the Bulgarian Black Sea coast and the possibilities for their localization and practical use.
