The first comprehensive study of Florida's springs was published in 1947. The next update was released 30 years later in the Florida Geological Survey Bulletin No. 31, Revised, "Springs of Florida". [6] In the 1977 Rosenau survey, there were sixteen offshore (under water) springs identified. All but two were situated on the Gulf coast.
[2] [5] Measurements between 1941 and 1972 reported flows which varied between 26,000 and 36,000 US gallons per day (98 and 136 m 3 /d), according to Florida Geological Survey Bulletin 66. [6] The most recent test in 2010 showed daily flow at just 6,000 U.S. gallons per day (23 m 3 /d).

Florida is tied with North Dakota as having the fewest earthquakes of any US state. [7] Because Florida is not located near any tectonic plate boundaries, earthquakes are very rare, but not totally unknown. In January 1879, a shock occurred near St. Augustine. There were reports of heavy shaking that knocked plaster from walls and articles from ...
The Florida Geological Survey fossil vertebrate collection (FGS) was started during the 1910s and was originally housed in Tallahassee. Under the direction of E. H. Sellards, Herman Gunter, and S. J. Olsen, the FGS collection was the primary source of fossil vertebrate descriptions from Florida until the early 1960s.
The hydrogeologic framework of the Floridan aquifer system was revised by the U.S. Geological Survey in 2015. [10] The extent of the system was revised to include some of the updip clastic facies which grade laterally into the Lower Floridan aquifer and have been previously included in the Southeastern Coastal Plain aquifer system, the Floridan ...
