Summary
Reviews two acoustic assessments for a planned Moray Firth seismic survey and reassesses marine mammal impacts using RAM and Bellhop propagation modelling. It compares predicted single-pulse and cumulative exposure with hearing and behavioural criteria, highlighting methodological uncertainty, near-field limitations and the dependence of potential effects on animal movement.
