Abstract
Two modelling programs were used to perform acoustic modeling for the New England Seamount Chain, both around the Atlantis II seamount and the caldera located southeast of Atlantis II. These programs were used for modeling NESMA (New England Seamount Acoustics Experiment) experiments in 2023 and 2024. Varying sound speeds and complex bathymetry within this ocean environment were used in the modelling to see any effects on acoustic propagation. For the Atlantis II seamount scenario, the results of the two models showed some slightly faster arrival times with the warmer water sound speed profiles, as well as showing multiple arrivals with varying interaction between the surface and bottom. Data analysis performed with acoustic data collected in NESMA 2023 showed these multiple sets of arrivals, some complicated by possible scattering and limited accuracy of the propagation models. The model results for the upcoming NESMA 2024 experiment provide insight into the acoustic propagation in the ocean environment around the caldera.
