This document is written for primary and secondary school student to explain the measurement of ocean flow using acoustic signal. In this document, principle and ferry mounted method of Acoustic Doppler Current Profiler (ADCP) measurement are introduced, and a part of results obtained through the measurement in the Tsugaru Strait is shown. Additionally, the importance of the measurement in the study of the Japan Sea is mentioned shortly.
