Keraudren Extension 3D Marine Seismic Survey—Acoustic Modelling
December 2019 — Western Australia
Client: Santos WA Energy Ltd.
Appendix H - Acoustic Modelling for Assessing Marine Fauna Sound Exposures
Source and propagation modelling of underwater sound associated with a planned 3-D marine seismic survey to assess potential acoustic impacts on marine mammals, fish, turtles, benthic invertebrates, sponges, coral, and plankton as part of Santos Ltd’s Environment Plan. Single-impulse sound fields were predicted at eight sites, and accumulated sound exposure fields were predicted for two representative scenarios for likely survey operations over 24 hours.
