Abstract :
We report the first success of a long-term (81 days) measurement using an in situ flow-through chemical analyzer, which was connected with a submarine cable for power supply and real-time data acquisition. The experiment was conducted at a plate boundary site in Sagami Bay, south of Japan, where a cable-connected submarine observatory (Hatsushima Underwater Observatory) has been available for geophysical and ecological monitoring studies. This study demonstrates a new possibility of application of submarine cables for advancing geochemical researches.
