Last week I had the pleasure of being a guest speaker for a Marine Systems Class at Florida Gulf Coast University (FGCU). The focus was on a chapter called the "Dynamic Shoreline" and I was happy to be able share some of the pictures I have taken on the dynamic shoreline of Cayo Costa Island. I was able to provide first hand knowledge of how the shoreline changes with the wind, water and waves through various pictures I have taken over the past 20 years. I enjoyed reviewing old notes, papers and books on Cayo Costa in preparation for this college class. Hopefully the students gained some knowledge and enjoyed my presentation as much as I did.
