The Kuroshio current turns toward the northeast while it passes the
Okinawa Trough in Taiwan's Northeast Sea. In this region, there are different
waters mixing, namely, water from the Taiwan Strait, water of the East China
Sea, and the Kuroshio current. During the year, except in the summer months,
the Kuroshio current is characterized by its distinct temperature difference
from other waters, i.e., the Kuroshio front is a predominant feature in this
region. The bottom topography in this region is composed of shelf and slope
features. The acoustics propagation is studied numerically using the FOR3D
code. Severe mode coupling is realized while the sound is transmitted through
the Kuroshio front. [Work supported by National Science Council of Republic of
