Abstract

During a May 2023 cruise of the New England Seamount Acoustics Experiment, a near-surface airgun was fired at 1-min intervals along a nominally semi-circular track centered on the Atlantis II seamount. Airgun shots were recorded by four hydrophones on a short vertical line array moored on the seamount plateau, providing up-slope acoustic propagation coverage for the eastern half of the Atlantis II flank. Focusing on hydrophone recordings of the first flank bounce return, comparison with numerical acoustics simulations reveals evidence of spatial (latitude/longitude) variation in geoacoustic properties of the seamount flank.
