AB We  expound on  a  hydrographic and  geophysical survey in  the south of  the  Archipelago of  San Andres, Providencia, and  Santa Catalina (ASAPSC) in  the  Colombian Caribbean Sea.  In  2017 and 2018, high-resolution data were acquired from the  Caribbean Center for Oceanographic and Hydrographic Research (CIOH). The hydrographic data were processed and  filtered per  International Hydrographic Organization (IHO) standards and  the  geomagnetic data were processed, corrected, and filtered to improve the inter-pretation. We  could then characterise the  submarine relief, ana-lyse the geomagnetic anomalies in the area, and identify different relief forms of  volcanic origin. Regarding geomagnetic work, a spectral analysis of  the  anomalies revealed highly magnetic bodies in  deep water and  residual magnetic anomalies strongly related to  the  seabed morphology. Magnetic highs associated with the  basement highs and volcanic cones were detected. Complementary spectral analysis showed that the  shallowest magnetic sources were in  the  first  500m,  whereas the  deepest magnetic sources were between the  depths of  4  and  5 km.  The geomagnetic data were also  validated using Euler deconvolution analysis, which confirmed these magnetic anomalies. Thus, a  dir-ect relationship between the magnetic anomalies and bathymetry of  the  seafloor was  confirmed, reinforcing the  theory of  the  vol-canic origin of these islands
