Cover Story: Vintage seismic profiles are critical for understanding subsurface geology, particularly in regions where modern high-resolution datasets are either costly or inaccessible. However, they often do not provide a complete understanding of subsurface features. By constructing velocity models using spline interpolation and smoothing techniques for time-to-depth conversion, based on interval velocities from a vintage seismic profile crossing the Sicily Channel (central Mediterranean Sea), this study aims to provide a comprehensive and quantitative understanding of subsurface geological features, in addition to a detailed analysis of geological structures and stratigraphy, providing insights into the distribution of volcanic bodies and sediment thickness across the region. View this paper
