Classification of the Sea Surface Processes Using Underwater Sounds over Dongsha Atoll
Abstract
The proposal is for an observational program to study the underwater ambient noise in a reef environment. Different sound sources co"ntribute to the overall ambient noise level variations in temporal, spatial and spectral space. This proposal will provide classific"ation of ambient noise sources and description of soundscapes in a reef environment. Dongsha reef atoll is a remote island over the" northern South China Sea. It is shielded from fishing and tourist activities. The annual precipitation on the island is ~1,300 mm." About 10~15 days each moth in May~August have rain with the monthly accumulation between 150 to 300 mm. This protected island is an idea environment for conducting underwater acoustic experiment. The objectives of this proposal are to establish an underwater acou"stic station for monitoring ambient noise level, classify and quantify wind and rain-generated noises and provide a description of s"oundscapes in a reef ecosystem. Passive Miniature Acoustic Recorders developed by the Applied Physics Laboratory University of Washington will be used for acoustic recording in various locations over the Dongsha atoll.
