Sub-bottom profiler images taken from the summit plateau of the Atlantis II Seamount reveal distinct seabed stratigraphy, including marine sediment, limestone, and basalt layers. Acoustic reflection data also show arrivals reflecting from this sub-bottom structure. A wavenumber integration model with elastic geoacoustic properties is able to reproduce the arrival pattern of seabed reflections and particularly the phase inversion of the sub-bottom return. The reflection model suggests that the limestone layer is eroded with high porosity and possesses a lower compressional velocity than a well-cemented layer. The model results also highlight the necessity of incorporating elastic effects for realistic geoacoustic characterization.
