This project is an R&D project led by the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) under the "Key and Advanced Technology R&D through Cross Community Collaboration Program (K Program)" to develop technology for the continuous monitoring of the vertical section of the ocean.

This project aims to develop technologies that enable near real-time visualization of underwater conditions by autonomously monitoring underwater acoustics and oceanographic parameters –such as temperature, salinity, and current flow–and analyzing their collected data.
To monitor underwater acoustic data, a cable system equipped with numerous hydrophones will be laid on the seafloor from the land-based station. The detected acoustic signals will be transmitted via optical fiber cable to computers in the land station, and the data will be processed to estimate the type of sound and their movement patterns. For oceanographic data, we will develop an unmanned surface vehicle powered by wind – similar to a sailboat – which will autonomously navigate and observe using onboard sensors. The collected data will be transmitted to land for analysis. We will develop an integrated system that combines these technologies: the Acoustic and Oceanographic Data Acquisition and analysis System (AODAS).
OPRI, in cooperation with JAMSTEC and Waseda University, works for the development of marine sound source catalog using recorded data of geographical, anthropological and biological sounds.
