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 (m.parsons@aims.gov.au) or Steve Simpson (s.simpson@bristol.ac.uk) for further information.

Status

IQOE is in its 9th year as a 10-year project and continues to implement of its Science Plan (available here). IQOE has successfully coordinated a variety of activities in ocean acoustics and bioacoustics through IQOE working groups on the use of acoustics to assess biodiversity, the importance of acoustic observations in the Arctic Ocean, standards for reporting ocean acoustic and bioacoustic data for IQOE, software for making acoustic observations comparable worldwide, and recommendations for implementation of an Ocean Sound Essential Ocean Variable for the Global Ocean Observing System. IQOE progress has been documented since June 2018 through IQOE Newsletters and since the beginning of the project through other products. IQOE identified 2020 as the Year of the Quiet Ocean because of evidence that ocean sound decreased because of decreases in human activities in the ocean due to the COVID-19 pandemic.

Next Steps

Activities in 2024 will include actions to help implement the Ocean Sound Essential Ocean Variable Implementation Plan; continuation of new activities on low-cost ocean acoustic observing systems and expansion of the Open Portal to Underwater Sound (OPUS), implementation of the Global Library of Underwater Biological Sounds, sponsorship of the second World Ocean Passive Acoustic Monitoring Day; and meetings of IQOE working groups and Science Committee.
