- Wikipedia, Feb. 1, 2021(Lens (hydrology), also called freshwater lens or Ghyben-Herzberg lens, is a convex-shaped layer of fresh groundwater that floats above the denser saltwater, usually found on small coral or limestone islands and atolls; this aquifer of fresh water is recharged through precipitation that infiltrates the top layer of soil and percolates downwards until it reaches the saturated zone)

Body of fresh ground water found typically beneath permeable limestone islands or peninsular land masses in the tropics. The lens-shaped water body is bounded above by a water table and below by a mixing zone between fresh and saline ground water along the halocline. In the center of the lens freshwater extends below sea-level, and another set of springs exists where dissolutional conduits associated with the lower limit of the lens intersect the rock surface below sea-level. 2. A lenticular form of a freshwater body under oceanic coasts.)
