Australian Marine Science Conference Eventranet 2017

Concurrent Session 3: S8: Noise impacts

Chair: Rachel Przeslawski
The extent to which anthropogenic noise in the world’s oceans impacts marine fauna is a subject of growing concern. Sources of marine anthropogenic noise include high-intensity acute sounds produced by activities such as military exercises, oil and gas exploration, pile-driving as well as lower-level chronic noise generated by commercial shipping and recreational and commercial fishing vessels. Many marine animals, from small invertebrates to large cetaceans, make extensive use of underwater sounds for important biological activities such as intraspecific communication, predator avoidance, navigation, larval orientation, foraging and reproduction. Potential effects of anthropogenic sound sources on marine animals range from disturbance that may lead to displacement from feeding or breeding areas, to auditory damage, tissue trauma and mortality. Alternatively, some marine species may experience no effect of exposure to intense sources, particularly if the spectral level does not exceed hearing thresholds. Presentations are invited from ecology, physics, and policy to showcase leading research on noise impacts on Australian marine life.
