Bob Allan Playa Overwash Sample, Florida Bay

A few months after Hurricane Irma hit Florida, a team from the Florence Bascom Geoscience Center conducted field work to determine what effects the storm had on islands in Florida Bay.  On Bob Allen island approximately 5.5 cm of mud (the upper layer shown here) were deposited by the storm.  The distinctive blue-green algal mat below the mud (visible where the block of storm deposited mud has been removed) made it easy to tell the thickness of the storm deposition.
