What does long-term monitoring of the ocean soundscape tell us?
International audience Mooring arrays of few hydrophones is an effective way for monitoring the ocean soundscape and its sources: undersea earthquakes and volcanic eruptions, marine mammals, iceberg cracks, sea-state, ship noise, etc. This is due to the exceptional acoustic properties of the ocean a...
