Fall 2018 Meeting – Victoria, BC, Canada
This annual report reviews activities of the Technical Committee on Acoustical Oceanography (TCAO) for the 174th and 175th meetings of Acoustical Society of America (ASA) in New Orleans, Louisiana and in Minneapolis, Minnesota. While we took our foot off the gas pedal this year after two internationally coordinated meetings in the previous year the AOTC enjoyed a wonderfully productive and eventful year.
A highlight is always our special sessions where we heard from scores of our talented researchers including 20 student papers. Here we focused on the topics of 1) Oceanographic contributions to ocean soundscapes, 2) Acoustic scattering from hydrocarbons and hydrothermal vent systems, 3) Biological effects on seabed geoacoustics, 4) Acoustics in estuaries, bays, inlets, fjords and rivers, 5) Acoustic seabed characterization, and 6) Ambient noise oceanography in polar regions. I thank all my skilled session organizers for their successful planning and execution of their sessions, many of which were live broadcast.
Over the year there were also several awards to be celebrated. At the New Orleans meeting Woods Hole Oceanographic Institution (WHOI) Senior Scientist Dr. Andone Lavery was the recipient of the 2017 Walter Munk Award where she delivered the prize lecture entitled “New platforms, technologies, and approaches for remote inference of physical and biological parameters using acoustic scattering techniques’’. Her citation reads “Through discrimination between the scattering by zooplankton and physical microstructure using broadband acoustic measurement methods and models, Andone Lavery has quantified important biological and physical parameters leading to new understanding of both ocean physical processes and marine biology ”. Also at the New Orleans meeting we acknowledged AO founding father Michael Buckingham for his Pioneers of Underwater Acoustics Silver medal, awarded to him by the Underwater Acoustics technical Committee. Michael’s citation reads “For contributions to the understanding of ocean ambient noise and marine sediment acoustics’’. Following along at the Minneapolis meeting WHOI Associate Scientist YT Lin was recognized with the AOTC Medwin Prize. Dr. Lin’s prize lecture was entitled “Three-dimensional shallow water sound propagation and applications toward acoustical oceanography’’, and his citation reads “For fundamental advances in 3-D shallow water acoustics and applications to geoacoustic inversion and marine mammal acoustics’’.
The AO students also shined during this past year with several exemplary papers. Award winners for New Orleans were in first place Elizabeth Weidner of the University of New Hampshire (UNH) with her paper entitled “Investigating bubble transport and fate in the watercolumn with calibrated broadband split-beam echosounder data’’ and in second place Jay Johnson of the University of Texas at Austin (UTA) with his paper “Variations in Ultrasonic Transmission Behavior Along Seagrass Leaf Blades’’. In Minneapolis the first place paper was given by Josée Belcourt of the University of Victoria with the title “Gradient-based Bayesian geoacoustic inversion for sediment properties at the New England mud patch’’ and getting equal second places was Matthew Zeh of UTA with his talk entitled “Acoustical characteristics and contributions of bubbles released from melting glacier ice’’ and Elisabeth Brown from Rensselaer Polytechnic Institute for her paper entitled “Implications from a clay/silt suspension model of mud for data from the Seabed Characterization Experiment’’. Well done students and I must say you made the judges life quite difficult because of the high quality of your work.
Continuing on the topic of awards, the AO and Underwater Acoustics (UW) technical committees are pleased to announce the establishment of the yearly Urick prize for the best AO or UW student paper published in the Journal of the Acoustical Society. The $500 prize is named in honor of Dr. Robert Urick of Catholic University of America who authored the classic and still very popular text book “Principles of Underwater Sound’’. We thank Charles Wiseman for helping establish the prize by offering to use a portion of the royalties from an upcoming re-issuing of the Urick text. We also thank Jim Miller, Chair of the Acoustical Society Foundation Board for turning the idea into a reality.
Lastly I want to thank everyone in the TC for all the effort that they put out this year in creating an energetic and dynamic atmosphere in AO and the greater society as a whole. We look forward to a productive and exciting year ahead.
Fall 2017 Meeting – New Orleans, LA
This annual report reviews activities of the Technical Committee on Acoustical Oceanography (TCAO) from the 172nd and 173rd meetings of Acoustical Society of America (ASA) in Honolulu, Hawaii, held jointly with the Acoustical Society of Japan and in Boston, Massachusetts, held jointly with the European Acoustics Association. These were extremely event filled meetings for the AOTC as we enjoy strong collaborations with our Pacific-rim and trans-Atlantic colleagues.
The year was particularly meaningful for the AOTC as we celebrated our 25th anniversary with a special session at the Honolulu meeting. The audience enjoyed invited talks from our TC founders, Michael Buckingham and David Farmer, ASA honorary fellow Walter Munk, and field luminaries Peter Worcester, James Lynch, Tim Stanton, Aaron Thode, Grant Deane, Martin Siderius, Ross Chapman, and Darrell Jackson. The 25th anniversary spirit continued at the Honolulu meeting with special sessions in two strong AO subject areas: Ocean Acoustic Tomography and Acoustic Scattering by Aquatic Organisms.
The high energy from the Honolulu meeting carried over to Boston which was co-hosted with the European Acoustics Association. In Boston we paid tribute to our colleague David Farmer whose remarkable career in theory, experimentation and engineering has touched if not created nearly every discipline of acoustical oceanography. Much to the delight of David, talks from students and colleagues addressed contributions to our understanding of turbulence, internal waves, mesoscale and submesoscale processes, air-sea interaction, Langmuir circulation, bubble acoustics, zooplankton, fish and marine mammal acoustics, sediment transport, and geoacoustics. Other successful special sessions in Boston included, Acoustic Measurements of Sediment Transport and Near-Bottom Structures, Acoustics and Acoustic Ecology of Benthic Communities, and Tools and Methods of Ocean Mapping.
Over the year there were also several awards. At the Honolulu meeting the AOTC was pleased to award the 2016 Medwin prize to Tom Weber of the University of New Hampshire (UNH) where the citation reads “In recognition of his work on the development and use of acoustic techniques for understanding and quantifying gas bubbles in the ocean’’. Dr. Weber delivered the Medwin address at the Honolulu meeting entitled “Acoustic observations and characterization of oceanic methane gas bubbles rising from the seabed’’. At the Boston meeting it was our pleasure to award the 2017 Medwin prize to Jennifer Miksis-Olds also of UNH. The citation reads “For the development of novel ocean acoustic field techniques and analyses for understanding marine life and ecosystems.’’ Dr. Miksis-Olds delivered the Medwin lecture entitled “ Exploring ocean ecosystems and dynamics through sound’’.
Fall 2016 Meeting – Honolulu, HI
This annual report reviews activities of the Technical Committee on Acoustical Oceanography (TCAO) from the 170th and 171st meetings of Acoustical Society of America (ASA) held in Jacksonville, Florida, in Fall 2015 and Salt Lake City, Utah, in Spring 2016, respectively. It has been a strong year for AOTC, with many well-attended sessions, a number of recipients of prestigious prizes and awards, and a resurgence in the number of student papers presented.
Two well-attended special sessions were organized by the TCOA at the Jacksonville meeting: 1) “Acoustics of High Latitude Oceans,” joint with SP, UW, and AB, chaired by Aaron Thode (Scripps) and co-organized by John Colosi (Naval Postgraduate School), and 2) “Passive-Acoustic Inversion Using Sources of Opportunity,” joint with SP and UW, co-chaired by Karim Sabra (Georgia Institute of Technology) and Kathleen Wage (George Mason University). In addition, there were 3 special sessions that AO co-sponsored: 1) “Direction of Arrival (DOA) Estimation, Source Localization, Classification, and Tracking Using Small Aperture Arrays,” co-sponsored with SP and UW and co-chaired by R. Lee Culver, (ARL, Penn State University) and Geoffrey H. Goldman, (US Army Research Laboratory), 2) “50 Years of Underwater Acoustics under ASA,” co-sponsored with UW, AB, and SP, chaired by David Bradley (Penn State University) and co-organized by John Colosi (Naval Postgraduate School), and 3) “Bioacoustics Research In Latin America,” co-sponsored with AB and co-organized by Juliana R. Moron (Universida de Federal de Juiz de Fora, Brazil) and Marie Trone (Valencia College). A very-well attended AO Hot Topics talk entitled Hot topics in “cold” acoustical oceanography was presented by Grant B. Deane (Marine Physical Laboratories, Scripps, University of San Diego), complementing the earlier session on the acoustics of high-latitudes. One of the highlights of this meeting was the 2015 Munk Award Lecture given by Carl Wunsch, an Emeritus Professor of Physical Oceanography at the Massachusetts Institute of Technology, during the Wednesday afternoon plenary session, entitled “Ocean acoustic tomography: Past, present, and maybe future”. The Munk Award is granted jointly by The Oceanography Society, the Office of Naval Research, and the Office of the Oceanographer of the Navy for distinguished research in oceanography related to sound and the sea. There were also an encouraging number of student papers presented, with the first place prize given to Katherine Wolfe, from the Georgia Institute of Technology, for her paper entitled “Optimized extraction of coherent arrivals from ambient noise correlations in a rapidly fluctuating medium, with an application to passive acoustic tomography”, and second place prize given to Graham Warner, from the University of Victoria, for his paper entitled “Environmental inversion using bowhead whale calls in the Chukchi Sea”.
The Salt Lake City meeting was punctuated by the presentation of the 2016 R. Bruce Lindsay Award to Megan S. Ballard, a member of the AOTC, for contributions to underwater acoustic propagation modeling and inversion techniques in acoustical oceanography. The R. Bruce Lindsay Award is presented in the Spring to a member of the Society who is under 35 years of age and who has been active in the affairs of the Society and has contributed substantially, through published papers, to the advancement of theoretical or applied acoustics, or both. Also at Salt Lake City, the 2016 Medwin Prize was awarded to Thomas Weber from the University of New Hampshire, also an AOTC member. The prize award lecture will be presented at the Hawaii meeting. The Medwin 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. The new incoming TCAO chair was announced at Salt Lake City, and a hearty congratulations goes to John Colosi (Naval Postgraduate School). There were three well-attended special sessions organized by the TCOA at the Salt Lake City meeting: “Acoustic Consistency of Ocean Models,” co-sponsored by SP, and organized by Tim Duda (WHOI) and Bruce Cornuelle (Scripps), 2) “Noise Impacts from the Industrialization of the Outer Continental Shelf and High Seas,” co-sponsored by AB, and organized by Michael stocker (Ocean Conservation Research), and 3) “Acoustical Oceanographic Tools for the Study of Marine Ecosystems,” co-sponsored by AB, and organized by David Barclay (Dalhousie University) and Wu-Jung Lee (Johns Hopkins University). Though the TCAO seems to be generally skeptical of live broadcasting of special sessions, the latter two special sessions were broadcast live and seemed to enjoy strong on-line attendance. In addition, there was a special session on “Sediment Characterization Using Direct and Inverse Techniques,” that AO co-sponsored with SP and UW and which was co-chaired by David Knobles (KSA LLC) and Preston Wilson (University of Texas at Austin). There were again a very healthy number of student papers presented, with the first place prize given to Scott Loranger, from the University of New Hampshire, for his paper entitled “An evaluation of the frequency response of hydrocarbon droplets”,
and the second place prize was a tie between Jacquelyn Kubicko, for her paper entitled “Passive ocean acoustic tomography using ships as sources of opportunity recorded on an irregularly spaced free-floating array: A feasibility study”, and Graham Warner, for his paper entitled “Time-difference-of-arrival localization of bowhead whales using asynchronous recorders”.
This report is my last 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.

This prize is given to recognize a person for the effective use of sound in the discovery and understanding of physical and biological parameters and processes in the sea. John was given the award for work on ocean internal waves as they relate to sound fluctuations in the sea. John will give the 2012 Medwin Prize lecture at the Kansas City ASA meeting.
There were some notable special sessions at the San Diego meeting including a memorial session in honor of Van Holliday. Van was one of the pioneers of Acoustical Oceanography and the session highlighted the many contributions Van made to the field. The session attendees included family members and numerous long time colleagues and it was obvious to all that Van had an enormous impact on both Acoustical Oceanography and on the people in the field. In San Diego there was also a special session honoring the work of Steve Schock on acoustic bottom characterization and sub-bottom imaging. This session was also very well attended and had a variety of invited speakers describe the many contributions Steve has been making on this topic as well as the continuing developments in this area based on Steve’s work over the years. The Hong Kong meeting had a very interesting special session on new technologies for active and passive monitoring of fish.
Fall 2011 Meeting — San Diego, California
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”.
