Canaveral National Seashore and Everglades National Park contain several of the largest, most intact, and most significant prehistoric shell mounds in Florida. These nationally significant archeological resources, which were key prehistoric/proto-historic monuments and settlements, later served as important navigational landmarks during the early European exploration and colonization of the Americas. Climate change is already producing severe, measurable, and detrimental impacts on these significant resources with irrevocable consequences. This project identified atmospheric and oceanic data or proxy records that can be used to examine climate change within these Florida parks. Identifying climate change resources will support future examination of the risks to cultural resources and will assist park staff as they develop strategies to adapt to a changing climate and to mitigate the impacts on cultural resource sites.
