What is World Ocean Passive Acoustic Monitoring Day?

WOPAM is an initiative to capture a snapshot of aquatic sound all over the world at the same time. Researchers worldwide are contributing their marine, freshwater, and brackish acoustic recordings for a large-scale collaborative study.

I had hydrophones deployed and recording from June 7th to 9th, how can I contribute and be involved in the initiative?

We'd love to have as many participants as possible! You can reach out to Miles Parsons ( or Sierra Jarriel ( for more information and to be included. Any sampling rates and recording cycles are welcomed.

When can I start to see the results of this effort?

Expected recording sites will be continually updated, but many of these recorders are part of larger studies and are deployed for months at a time. As a result, the goal for collection of sound data from all participants is by next WOPAM day (June 8th, 2024). Study results will begin to emerge after that.
