Fall 2015 Meeting — Jacksonville, FL

Annual Report: Fall 2014 (Indianapolis, IN) and Spring 2015 (Pittsburgh, PA)

This annual report reviews activities of the Technical Committee on Acoustical Oceanography (TCAO) from the 168th and 169th meetings of Acoustical Society of America (ASA) held in Indianapolis, IN in Fall 2014 and Pittsburgh, PA in Spring 2015, respectively.

 

Two well‐attended special sessions were organized by the TCOA at the Indianapolis meeting: 1) “Education in Acoustical Oceanography and Underwater Acoustics,” joint with UW, and co‐chaired by Andone Lavery (Woods Hole Oceanographic Institution), Art Baggeroer (Massachusetts Institute of Technology), and Preston Wilson (The University of Texas at Austin), and 2) “Parameter Estimation in Environments that Include Out‐of‐Plane Propagation Effects,” joint with UW and SP, co‐chaired by Megan S. Ballard (Applied Research Laboratories, The University of Texas at Austin), and Tim Duda (Woods Hole Oceanographic Institution). In addition, there were 3 special sessions that AO co‐ sponsored: 1) “Mobile Autonomous Platforms for Bioacoustic Sensing,” co‐sponsored with AB and SP and organized by Holger Klinck (Oregon State University) and David Mellinger (Oregon State University), 2) “Standardization of Measurement, Modeling, and Terminology of Underwater Sound,” co‐sponsored with UW, AB, and ASA Committee on Standards and co‐organized by Susan Blaeser (ASA Standards), Michael Ainslie (TNO, The Netherlands), and George Frisk (Florida Atlantic University), and 3) “Use of Passive Acoustics for Estimation of Animal Population,” co‐sponsored with AB and organized by Tina Yack (Bio‐Waves Inc.) and Danielle Harris (University of St. Andrews).

 

The highlight of the Pittsburgh meeting was the 2015 Medwin Prize Lecture, presented by Karim Sabra from the Georgia Institute of Technology, entitled “Monitoring deep ocean temperatures using low‐frequency ambient noise”. This prize recognizes the accomplishments of young and mid‐ career scientists involved in research that addresses the effective use of sound in the discovery and understanding of physical and biological parameters and processes in the sea. Also at the Pittsburgh meeting, AO sponsored a special session on “Acoustics of Fine Grained Sediments: Theory and Measurement”, joint with UW, organized by David Knobles (Applied Research Laboratories, The University of Texas at Austin), Mohsen Badiey (University of Delaware), and Charles Holland (Applied Research Laboratory, Penn State University). This session was well‐attended and generally considered to be a success.
This report is my second as Chair of the AO Technical Committee. I want to close by thanking the volunteers who made the activities of the AO Technical Committee possible this year. I look forward to continuing to work with the AO Technical Committee and the ASA community more broadly for the remaining year of my term.

Annual Report: Fall 2010 (Cancun), Spring 2011 (Seattle)

At the 161st meeting in Seattle, the 2011 Medwin Prize in Acoustical Oceanography was awarded to Aaron Thode for his contributions to Acoustical Oceanography. His Acoustical Oceanography research has been primarily in marine mammal acoustics but Aaron has also made numerous contributions to Underwater Acoustics and Signal Processing. The Medwin Prize was formally presented at the awards ceremony. Also during the Seattle meeting, Aaron gave the prize lecture, “Skipping stones along the boundary between marine mammal acoustics and acoustical oceanography” to a room filled to capacity. The audience was clearly fascinated by the images and sounds he presented that summarized years of research.

In Seattle, a very successful fisheries workshop was held that was co-sponsored by the ASA the American Fisheries Society. The workshop title was, “Acoustic Challenges in Aquatic Ecosystem Assessment”. This was very well attended with posters and lectures presented over a two day period in parallel with the ASA meeting. The workshop organizers were John Horne, (University of Washington), Robert McClure (BioSonics Inc.), Charles Schmid (Acoustical Society of America) and Martin Siderius (Portland State University).

In 2011 there were several outstanding special sessions at both the Cancun and Seattle meetings. At the Cancun meeting there was “Acoustics of Fish Schools and Bubble Clouds” about experimental evidence and theoretical descriptions of low frequency resonances associated with fish schools and wave induced bubble clouds. This session organizer was Orest Diachok. Also in Cancun was the special session, “Remote Sensing with Ambient Noise” on using noise and interferometric methods to obtain information about the environment. Peter Gerstoft and Martin Siderius organized this session. Both Cancun sessions were well attended and had many contributed papers as well as invited lectures. In Seattle, Brian Dushaw and Tim Duda organized “Ocean Observing Systems: Acoustical Observations and Applications” on passive and active acoustic methods for long-term observations of physical, chemical, and biological processes. This session had invited speakers that spanned a wide variety of topics related to ocean observing systems and also had an impressive number of contributed papers. Also in Seattle Jim Lynch organized the special session “Integrating Ocean and Acoustic Observations With Models”. This session was primarily about improving results from forward and inverse problems by including physical, oceaongraphic, geologic, or biologic information in ocean models. Acoustical Oceanography was also featured in the Hot Topics session in Seattle where Brian Dushaw gave the lecture “Building the oceanic concert hall: Multidisciplinary applications of acoustic for ocean observing systems”.
