• Acoustic Modelling Phase 2 Report
In support of Woodside’s Supplement Report to the Draft Environment Impact Statement, JASCO performed two modelling studies of underwater noise related to Mobile Offshore Drilling Unit (MODU) and Floating Production Storage and Offloading (FPSO) operations to determine ranges to acoustic exposure thresholds for marine mammals, turtles, and fish. The third study employed animal movement (animat) modelling simulations to predict the range at which pygmy blue whales could be expected to be exposed above threshold criteria for permanent threshold shift (PTS), temporary threshold shift (TTS) and behavioural response.
