Data underlying the publication "Vulnerability of Key Sea Turtle Nesting Beaches to Future Erosion and Sea Level Rise"

This dataset contains the data underlying the analyses presented in the publication "Vulnerability of Key Sea Turtle Nesting Beaches to Future Erosion and Sea Level Rise" in Earth's Future (2026). This is based on Chapter 4 of the PhD thesis "Coastal Science for Sea Turtle Conservation" by Jakob C. Christiaanse. In that study, we combined satellite-derived shorelines (CoastSat), shoreline modeling (CoSMoS-COAST), and global datasets to analyze the shoreline evolution, characteristics, and future vulnerability of nine globally important sea turtle nesting beaches. We identify seasonal and long-term shoreline change patterns, hindcast (1980-2024) and forecast (2025-2100) shoreline positions under various sea level rise scenarios, and quantify available accommodation space based on backbeach elevation and infrastructure footprints. This dataset includes the satellite satellite-derived shoreline positions, model input (hydrodynamics, slope, shorelines) and output (hindcast and forecast shoreline positions), and backbeach characteristics for each study site. The Matlab model code used to run the shoreline predictions is also included. Please cite this dataset and the published article (link below) when using this data:<br>Christiaanse, J.
