Abstract
Ocean acoustic tomography has enjoyed success at shorter ranges (<2 Mm) by using ray theory to model the acoustic propagation. As the ranges of these experiments increase to basin and global scale it is necessary to consider the dispersive effect of the medium by using mode theory to model the propagation. This is useful at shorter ranges as well to correctly interpret the final cutoff which contains a substantial amount of energy for axial transmissions
