    Abstract: During the Atlantic Deepwater Acoustic Observing Network experiment, 6 acoustic landers were deployed from 2018 through 2020 to measure long term acoustic soundscapes. In collaboration with the sea-going team, an acoustic model for wind and ships was developed including source distribution, source level and acoustic propagation models. In this paper a presentation of the modeling approach will be given. The model will be compared with the observations. The acoustic models included uncertainty in oceanography, ship source level and depth, and significant geo-acoustic sediment parameter uncertainty. An immediate result of this comparison is that the sediment can be inferred by comparing the statistics of the observation with those of the model.
