Appendix I – Acoustic Modelling for Assessing Marine Fauna Sound Exposures
A numerical modelling study of underwater sound levels associated with the planned marine seismic survey to assist in understanding the potential acoustic impact on receptors including marine mammals, fish, sea turtles, and invertebrates. Three seismic airgun array sources were modelled conducting 2D and 3D surveys in the Bonaparte Basin, and three of JASCO’s sound propagation models were used in combination to characterise the acoustic fields at short and long ranges at frequencies between 5 Hz and 25 kHz.
