ADVANCED NOTICE Marine Acoustics Special Session 2006 Ocean Sciences Meeting, Hawaii The 13th Ocean Sciences Meeting, a joint meeting of ASLO, TOS and AGU, will be held 20-24 February 2006 in Honolulu, Hawaii. The Program Committee is developing a scientific program that will cover all topics in the area of Ocean Sciences and one of these topics will be marine acoustics. Session Summary From the use of hydroacoustic monitoring to detect and locate submarine earthquakes and volcanic activity to navigation cues for young reef fish finding their way home marine acoustics is a rapidly expanding area of research and development. Increasing concerns of the effects of underwater noise, both anthropogenic and natural, on the marine environment are raising marine acoustics to the forefront of scientific research and to government policy and legislation. This session will include the following: Acoustic tomography for water mass monitoring and climate research Acoustic techniques for habitat classification, fish and plankton abundance and biomass modelling Acoustic techniques advancing marine archaeology Seafloor acoustics, mapping topography and military surveying for vessels and mines Acoustic remote sensing of the marine environment Underwater acoustic communication and navigation, people and animals Advances in acoustic technologies The effect of anthropogenic and natural noise on marine life Abstract submissions will be accepted on line in the very near future at http://www.agu.org/meetings/os06/.
