Abstract: A scientific report presenting a three-dimensional crustal structure analysis of Ascension Island using active source seismic tomography. The primary geographic focus is Ascension Island, located in the South Atlantic Ocean. The document includes data and interpretations derived from seismic surveys conducted to investigate the island's subsurface geological features. The time period explicitly addressed in the report corresponds to the dates of seismic data acquisition and analysis, which are contemporary to the study's publication. The report is structured as a detailed geophysical survey and analysis, incorporating seismic tomography methods to map crustal variations beneath Ascension Island. The subject domains discussed encompass geophysics, seismology, and volcanology, with emphasis on crustal composition, tectonic structures, and volcanic processes. The document includes technical descriptions of seismic data collection, processing techniques, and tomographic inversion results. Ascension Island is treated as a case study for understanding crustal architecture in an oceanic island setting. The report contributes to the broader field of earth sciences by providing empirical seismic data and interpretations relevant to crustal dynamics and volcanic island formation. The document is intended as a comprehensive scientific account of the seismic investigation and its findings related to the crustal structure beneath Ascension Island.
