Submarine springs of fresh water in the region from Cape Feolent to Cape Sarych

We performed a search for local coastal submarine springs of fresh water in the region from Cape Feolent to Cape Sarych (down to an isobath of 40m). Stable submarine springs of brackish water with the minimum salinity of 5.5‰ and the minimum total output of 30,000 m3/day were discovered only near the west wall of Cape Aiya. It is shown that brackish waters discharging from these springs spread over the sea surface in the form of a thin layer (up to 1 m in thickness) characterized by lower salinity, higher transparency, and an elevated content of silicic acid. We make a conjecture that the appearance of 2–3-m-thick layers of water with higher transparency and lower salinity at depths of 5–8 m is explained by the discharge of unknown bottom springs of underground fresh water.
