AXIAL

The research goals of the AXIAL cruise are to collect a combination of 3D seismic reflection data and a set of longer 2D seismic reflection profiles in order to image the complex 3D nature of the Axial volcano. We aim to understand the magma transport mechanisms within and above the crustal reservoir, image the 3D nature of the fracture network of the chamber, and to connect the subsurface features to the vents and fissures on the ocean floor. Previous seismic refraction data imaged a large and long-lived crustal magma reservoir beneath the caldera and later reflection profiles identifies a fracture network above the volcano.
