Methods: We integrated geomorphological mapping, multi-decadal shoreline extraction with CoastSat (1986–2024; EPR), Ground Penetrating Radar (GPR) profiles, paleoshoreline detection from high-resolution DEM, and paleo/future sea-level scenarios. Results: Net shoreline retreat averaged ~–2.0 m yr⁻¹ (max erosion in 1986–1996; localized accretion after 2021), linked to sediment budget shifts and engineering structures. GPR reveals erosional surfaces/terraces guiding present morphodynamics. Paleo sea-level highstands (MIS5e +6 m; mid-Holocene +3 m) and a 2100 SLR scenario overlap low-lying inherited surfaces. Discussion: Coupling surface (CoastSat) and subsurface (GPR) evidence clarifies multi-scale controls on instability and maps exposure hotspots, supporting ecosystem-based, adaptive coastal management in this urbanizing sector.}, publisher = {Frontiers Media SA}, keywords = {coastal dynamics}, keywords = {sea level rise}, keywords = {paleoshorelines}, keywords = {geospatial analysis}, keywords = {Colombian Caribbean Sea}, keywords = {coastal sedimentology}, keywords = {climate change}, keywords = {ground penetrating radar (GPR)}, title = {Coastal dynamics and geomorphology of the Pozos Colorados sector, Santa Marta: an analysis of sea level rise and paleo-shoreline}, doi = {10.3389/FMARS.2025.1700038}, author = {Villate Daza, Diego Andrés and Barboza Pinzon, Eduardo Guimarães and Jigena Antelo, Bismarck and Muñoz Pérez, Juan José and Anfuso Melfi, Giorgio and Portz, Luana Carla and Afanador Franco, Fernando and Portantiolo Manzolli, Rogério}, }
