The most extensive areas of pale colors (i.e., shallowest depths mapped) are around the Marquesas Keys and along the inner shelf of the middle and upper Keys. When the water level in the underlying limestone aquifer is depressed (due to drought or consumptive uses), the void spaces that once held water now are filled with air. The extensive carbonate rocks of Florida are inherently porous and have been exposed to weathering processes since the last significant interglacial period led to widespread flooding about 130,000 years ago.
