3d Acoustic Mapping of the Kuroshio (Taiwan Current) off the Southeast Coast of Taiwan

Abstract

The long-term monitoring of the western boundary current (WBC) is still a challenging issue in the operational oceanography. The surface current of the WBC can well be measured by a pair of advanced high frequency ocean radars, located at the shore washed out by the WBC. However the radar has little capability of measuring the subsurface structures of WBC. The Argo floats might not be suitable to monitor the WBC at a fixed point because deployed floats quickly run away from the observation site. The travel-time ocean acoustic tomography (OAT) from the axis of the underwater sound channel (USC) is an unique, cost-effective technology for measuring the temporal variations and 3D structures of WBC.
