Joint US-Japan Ocean Acoustic Waveguide Remote Sensing Experiment
Abstract
Approved for Public Release - The purpose of the proposed research is to explore the marine environment with long-range wide-area ocean acoustic sensing in the territorial waters of Japan. The specific emphasis is on passive and active sensing from the lens of the most advanced long-range active and passive underwater acoustic sensing systems available. The proposed experiment will be conducted over large portions of the maritime exclusive economic zone of Japan where the marine environment is similar to neighboring regions along the east Asian continental shelf, which spans the maritime zones of the Peoples Republic of China, North and South Korea and the Russian Federation. The topics of these experiments will include wide area sensing of a variety of economically, ecologically and strategically important fish species with active Ocean Acoustic Waveguide Remote Sensing (OAWRS) as well as passive OAWRS sensing (POAWRS) of marine mammals over large areas. Japan is particularly interested in OAWRS for efficiently sensing its fish populations, which also appear as significant clutter when actively sensing for other submerged objects. Japan is eager to host this first demonstration and use of OAWRS in Asian waters. A number of other unique ocean acoustic data sets will be collected in the process. This will include reverberation, geoclutter, ambient noise, and transmission scintillation data, as well as propagation data in continental shelf, deep water, shelf break, and canyon environments where the East China Sea and Sea of Japan merge with the Western Pacific Ocean.
