Coastal Soundscape Around Japan

The coastal waters around Japan are highly diverse, supporting a range of tropical, warm, and cold-water species. During the winter, strong monsoons sweep across Japan from west to east, creating a stark contrast between the sea conditions on the Japan Sea side and the Pacific Ocean side. To understand coastal soundscape, we monitored underwater sounds at 10 coastal sites around Japan to collect baseline data for the environmental assessment of potential offshore wind farm projects. Obtained data highlight regional and seasonal differences.
