The Consortium for Ocean Leadership (COL) coordinated a full-day hybrid-format workshop on 29 April 2022 to gather input from the ocean sound and acoustics community to contribute to the Maritime Acoustic Environment (UN-MAE). The workshop was supported by the Richard Lounsbery Foundation. The summary report in English is listed below, as well as translations into Arabic, Hindi, Mandarin Chinese, and Spanish.
World Oceans Passive Acoustic Monitoring Day (WOPAM Day)
Passive acoustic monitoring (PAM) has developed significantly over the last 20 years and hydrophones are now being deployed in more locations, more often, by more people, than ever before. To celebrate the increasing breadth of the application of PAM around the world, and help promote public awareness of Ocean Sound to an increasingly interested global community, a new initiative has proposed a celebration of aquatic PAM on World Oceans Day (June 8).
Through the Global Library of Underwater Biological Sounds (GLUBS), a call has gone out to hydrophone operators for their interest to participate in a World Oceans Passive Acoustic Monitoring (WOPAM) Day. The premise for the first year of this initiative is simple; to share data from any already planned deployments recording on June 8th for a collaborative study of our global aquatic soundscapes, whether in salt, brackish or freshwater.
So, if you already have a hydrophone in the water, that will be recording on June 8th (or have a planned project to deploy before then), and are interested in participating in WOPAM Day, please contact Miles Parsons (email@example.com) or Steve Simpson (firstname.lastname@example.org) for further information.

The IQOE Working Group on Acoustic Measurement of Ocean Biodiversity Hotspots and other colleagues have published an article calling for a Global Library of Underwater Biological Sounds (GLUBS) (see article at https://www.frontiersin.org/articles/10.3389/fevo.2022.810156/full and press release at Global Library of Underwater Biological Sounds, “GLUBS,” Will Help Monitor Changing Marine Life (constantcontact.com)). The latest IQOE Newsletter is available here. IQOE is co-sponsored by the Scientific Committee on Oceanic Research and Partnership on Observation of the Global Ocean.
IQOE has been compiling metadata about hydrophone deployments for the past two years. This database includes records for about 600 current and past hydrophone deployments. A map as of 8 August 2021 is given at https://www.iqoe.org/systems. I am in the process of updating this static map.
We know that static maps on a specific date do not present a complete picture of hydrophone deployments. We are in the process of updating the hydrophone database to make it possible to create maps for a range of dates to provide more complete information. We are also adding the possibility to show mobile deployments that start and end at different geographic coordinates.
The updated database will be integrated with the IQOE Website. It will not contain acoustic data for the hydrophone deployments, but will contain metadata for each one, including contact information, that will make it easier to obtain data.
If you have not yet submitted hydrophone metadata for the existing database—for current or past deployments and stationary or mobile deployments—and would like to get your metadata into the database, please submit your metadata on the input form.
Apart from providing a community resource, IQOE hopes to use the database to identify data holders who can help create time series of ambient ocean sound for different parts of the ocean by the end of IQOE in 2025.
Please forward this email to anyone you think would be interested in submitting metadata.
