| Summary: | Jasper Seamount is a submarine volcano in the Fieberling-Guadalupe seamount trail, located off the coast of Baja California, Mexico. It rises from the 4000-m-deep seafloor to a summit depth of 700 m. Detailed geophysical, geochemical, and geological studies there provide an in-depth geological understanding of a seamount that approaches our knowledge of subaerial volcanoes. Active-source seismic experiments at Jasper Seamount resulted in the first seismic velocity models of an intraplate seamount. Marine gravity and magnetics surveys, combined with analyses of the physical properties, geochemistry, and geochronology of dredge samples, enabled scientists to develop a detailed model of its internal structure.
