Australian Marine Science Conference Eventranet 2017

Concurrent session 3:S7: The use of acoustics for the exploration and management of the marine environment.


Chair: David Williams and Kim Picard
The field of acoustics is developing rapidly due to quantum changes in electronic miniaturisation and availability of smaller and at the same time more powerful computing facilities. Acoustics work well in sea water, the signal can readily propagate through the water column and the result can be rich in information on ocean currents, suspended matter, ocean bed properties, net material fluxes, imagery and fish passage. Acoustic technology can be used from both fixed and moving platforms and is suitable to use from all our existing vessels as well as the newer platforms such as ROV’s and AUV’s. Acoustic methods encompass both passive and active acoustics. Passive acoustic examples are fish tagging methods and noise logging. Both have revealed new insights in biological oceanic processes and have allowed new links between biology and physics to be formed. Active acoustic examples are current profilers and multi beam echo sounders. The rapid advancement of these technologies are allowing never before seen detail in ocean processes to come to light in reasonable simplicity and in near real time. Presentations are invited from all acoustic related fields.
