Abstract
In this study, we measured the effects of ambient noise generated by wind and ship traffic on the ocean sounscape, with a focus on low-frequency bands (<1 kHz). The speed and direction of the wind were measured from a weather buoy operated by the Korea Institute of Ocean Science and Technology (KIOST). The hydrophone near the weather buoy was moored for one month to measure ambient noise. The measured ambient noise was analyzed using wind data from the weather buoy and automatic identification system (AIS) data, i.e., navigation information, of sailing vessels in the vicinity of the study area. From the analysis results, we confirmed that the measured ANL at 1 kHz increased as ships approached the hydrophone and fluctuated according to the speed and direction of the wind.ted by the Korea Institute of Ocean Science and Technology (KIOST).
