Marine Noise Monitoring and Impacts


Objective: Describe the acute and chronic effects of seismic and vessel operations on key sensitive receptors (plankton, marine invertebrates and fishes) under real-world conditions.

Increasing noise levels in the marine environment may affect animal behaviour
