Se reconstruyeron los paisajes arqueológicos sumergidos frente a la costa de Cartagena de Indias con base en datos batimétricos multihaz de alta resolución provenientes del Servicio Hidrográfico de la Dirección General Marítima de Colombia y la comparación de mapas históricos de 1772, 1854, 1935, 1995 y 2021. Se demuestra que la construcción de la escollera de Bocagrande ha significado la acreción del terreno en este punto en cerca de 44,4 Ha, y que los espolones colocados en la playa en el siglo pasado lo han sostenido. The submerged archaeological landscapes off the coast of Cartagena de Indias were reconstructed based on high-resolution multibeam bathymetric data from the Hydrographic Service of the General Maritime Directorate of Colombia and on the comparison of historical maps from 1772, 1854, 1935, 1995, and 2021. We show that the construction of the Bocagrande breakwater has meant the accretion of around 44,4 Ha of land in Bocagrande and the spurs placed on the beach in the last century have sustained it.
