The IMOS passive acoustics facility has made passive acoustic data from four sites around Australia publicly available since 2008 at one site, although funding now may cause a temporary pause. This document summarizes the facility. The operation of the IMOS facility could be considered a model for how passive acoustic data can be disseminated. One can go to https://acoustic.aodn.org.au/acoustic/, choose a deployment, an 18-day spectrogram will pop up and if one has the right browser, click somewhere and the nearest samples’ spectrogram and waveform pop up with an option to download the sample. It is easy, for example, to locate whales this way.
IQOE sponsors are contributing to SeaBASS 2018 (see https://marine.unh.edu/seabass). Applications are sought for students to participate in the summer school. Local support (lodging and meals) will be provided for accepted students. 2-3 students from developing countries will additionally have their travel costs supported by the Scientific Committee on Oceanic Research (SCOR).
This workshop on 6 May 2018 in Minneapolis, Minnesota, USA will provide an update on the activities of the International Quiet Ocean Experiment (IQOE) in relation to the effects of ocean noise on marine organisms and will provide an opportunity for the broader ASA community to influence IQOE activities through discussions as part of the workshop. The agenda for the session will be posted on this site when it is available. See Workshops page of IQOE Web site.
IQOE launched its re-designed Web site.
On 12 September 2017, IQOE announced the formation of the IQOE Working Group on Arctic Acoustic Environments. The group is co-chaired by Philippe Blondel (UK) and Hanne Sagen (Norway). The working group will coordinate national acoustic observations, research, and modelling in the Arctic Ocean and will compile of baseline acoustic data.
On 15 August 2017, IQOE announced the formation of the IQOE Working Group on Data Management and Access. The chair of the group is Robert McCauley. Other members include Lucy Dickinson (UK), Robert Dziak (USA), Tryggvi Edwald (Austria), Torill Hamre (Norway), Reyna Jenkyns (Canada), Niels Kinneging (Netherlands), G. Latha (India), Marie Roch (USA), and Carrie Wall Bell (USA). The group will develop data management and data access policies for scientists and data centers involved in the program.
On 11 July 2017, the IQOE Executive Group changed broadened the scope of the IQOE Working Group on Acoustic Measurement of Biodiversity on Coral Reefs to include other high-biodiversity areas (e.g., deep-water reefs, mangrove forests, and kelp forests) and changed the name of the group to the IQOE Working Group on Acoustic Measurement of Ocean Biodiversity Hotspots.
On 28 January 2017, the IQOE Science Committee approved the formation of the IQOE Working Group on Acoustic Measurement of Biodiversity on Coral Reefs. The group is co-chaired by Bishwajit Chakraborty (India) and Aran Mooney (USA). Other members of the group include Lucia di Iorio (France), Sophie Nedelec (UK), Marc Lammers (USA), David Lecchini (French Polynesia/France), Miles Parsons (Australia), Craig Radford (New Zealand), Jenni Stanley (USA), and Tzu-Hao Lin (China-Taipei). IQOE formed this working group to help bring together scientists from the global community with an interest in studying the acoustics of coral reef areas.
The Consortium for Ocean Leadership (COL) has funding from the Richard Lounsbery Foundation to advance U.S. multi-stakeholder collaboration on ocean sound data, research, and observation. As part of this effort, which will build U.S. engagement and leverage scientific resources and investment in support of the IQOE, COL will document the full landscape of U.S. ocean sound-related programs, task teams, and data sets; foster participation by academic scientists, federal agencies, and industry and conservation stakeholders; provide a forum for U.S. ocean sound‐related discussions and collaborations; and promote the need for a coordinated U.S. ocean sound science program aligned with the goals of IQOE and national priorities.
National Workshop on Passive Acoustic Sensors, Measurements and Calibration--This workshop was held at NIOT Chennai, on October 14, 2016. Twenty-seven individuals participated in the meeting, including representatives from the Indian Navy, fisheries agency, National Institute of Oceanography-Goa and the Indian Institute of Technology-Delhi. The workshop was opened with an inaugural presentation by Dr. S.C. Shenoi, Director, NIOT, followed by a talk on the importance of passive acoustics for monitoring underwater environments and the objectives of IQOE by Dr. Bishwajit Chakraborty, CSIR-NIO. Dr. G. Latha covered detailed technical aspects of passive acoustics and work carried at the NIOT over the past decade. Dr. G. Ramdas spoke about underwater acoustic techniques, both including active and passive approaches. Ms. Malarkodi described the Acoustic Tank Facility and detailed the calibration work being carried out at the NIOT facility. There were lab visits and a panel discussions on passive monitoring and related technical issues by the participants.
