Toward real-time seafloor observatories

点击翻译按钮获取中文摘要

In this study, several sea experiments were conducted throughout the research period, which led to success in installing high-precision differential pressure gauges to existing seafloor electromagnetic stations. This implies that the stations can now serve as client sensors of seafloor tsunami early warning systems. In addition, it was found that a method to attach acoustic telemetry modems to the seafloor stations and to place sea-surface buoys with satellite links just above the stations is superior to existing methods in terms of its efficiency and cost.
