was initiated <strong>and</strong> have increased to present day levels. This increase in energy can potentially be<br />

tied to rising sea level.<br />

This study is one <strong>of</strong> <strong>the</strong> first <strong>of</strong> its kind to be conducted in <strong>the</strong> United States. It is also<br />

one <strong>of</strong> <strong>the</strong> first studies <strong>of</strong> barrier isl<strong>and</strong> <strong>evolution</strong> conducted along <strong>the</strong> Panh<strong>and</strong>le coast <strong>of</strong><br />

Florida.<br />

Future work should involve <strong>the</strong> compilation <strong>of</strong> a more robust data set. Additional grain<br />

size samples should be collected to provide a more robust set <strong>of</strong> granulometric data. Future work<br />

should also include a more detailed dating program. Ideally, several OSL dates should be<br />

obtained from within each beach ridge set. This would refine <strong>the</strong> progradation rate calculations<br />

made in this investigation <strong>and</strong> provide a higher resolution record <strong>of</strong> <strong>the</strong> progradation history <strong>and</strong><br />

<strong>evolution</strong> <strong>of</strong> St. Vincent Isl<strong>and</strong>. A full LIDAR survey would also provide <strong>the</strong> information<br />

required to accurately estimate <strong>the</strong> number <strong>of</strong> beach ridges within each beach ridge set. The<br />

estimates could <strong>the</strong>n be used to provide a more accurate estimate <strong>of</strong> beach ridge formation rates.<br />

Additional work should also include <strong>the</strong> collection <strong>of</strong> GPR data that covers a larger portion <strong>of</strong> <strong>the</strong><br />

isl<strong>and</strong>. This data could <strong>the</strong>n be used to fur<strong>the</strong>r refine <strong>the</strong> current estimates <strong>of</strong> <strong>the</strong> position <strong>of</strong> <strong>the</strong><br />

pre-barrier Pleistocene contact. Additional work using low frequency GPR is also<br />

recommended. The greater penetration provided by <strong>the</strong> lower frequency units will provide a<br />

better underst<strong>and</strong>ing <strong>of</strong> subsurface stratigraphy <strong>of</strong> <strong>the</strong> isl<strong>and</strong>. This underst<strong>and</strong>ing could be<br />

fur<strong>the</strong>r refined by <strong>the</strong> collection <strong>of</strong> borehole data from locations across <strong>the</strong> isl<strong>and</strong>.<br />
