In detail
Crescent Beach Submarine Spring is located 3.9 km from the coast of Florida.
The ocean ground at this location is some 18 m deep but the spring vent is at the depth of 38 m. This “hollow” or “spring pool” has a diameter of some 25 m.
On a calm day the spring boil can be seen on the surface of ocean – it beats through 18 m thick layer of water!
Discharge
Most likely, this is a first magnitude spring (1.) with an extremely powerful discharge that thus far has not been measured. Exact discharge of Crescent Beach Submarine Spring is not known but some assessments mention up to 40,000 l/s what would make it the most powerful spring in Florida and USA and… world? Some other sources modestly mention that this is “at least 2nd magnitude spring”…
Freshwater or – almost freshwater
Spring water is slightly saline (6 g/l) contrary to the surrounding seawater (35 g/l). The smell of hydrogen sulfide (old boiled eggs) can be felt near this place.
It has been observed that the power of the spring fluctuates – after heavy rain the spring is more powerful.
Geology
Crescent Beach Submarine Spring has formed in a location where the “cover” over the Floridian Aquifer – clay-rich Miocene and Plio-Pleistocene formations – has been eroded and the Eocene formation – Ocala Limestone is exposed.
Spring formed during the ice ages, when the level of ocean was lower and this land was above the sea level.
History
Crescent Beach Submarine Spring is known since at least 1875 when the U.S. Coastal Survey made the first bathymetric maps of the area. But there are stories that this location was used to get fresh water on ships long before this.
