Since 2018, I have participated in extensive sea-going experiments. The purpose of these experiments is to establish the feasibility of long-range underwater acoustic communication in deep water near South Korea. My roles in these experiments are as follows: (1) Designing the entire experiment plan as hands-on staff (e.g., entire timetable, ship track, range between source and receiver, source/receiver depth, etc.), (2) collaborating with and communicating with companies that manufacture the source and receiving equipment, and (3) analyzing the experimental data obtained from the receiver.
