Zooplankton dynamics were investigated based on samples collected monthly during the period between November 1998 and October 1999 at 15 stations in Gwangyang and Sachon Bay. Zooplankters were quantitatively collected with horizontal towing through the su
In order to fast predict the wind-driven current in a small bay, a convolution method in which the wind-driven current can be generated only with the local wind is developed and applied in the Sachon Bay.
The root mean square(rms) ratio defined as the ratio of the rms error to the rms speed is 0.37. The rms ratio is generally less than 0.2, except for all the mouths of Jinju Bay and Namhae-do and in the region between Saryang Island and Sachon. The spatial average of the recover rate of kinetic energy(rrke) is 87 %. Thus, the predicted wind-driven current by the convolution model is in a good agreement with the computed one by the numerical model. The ratio of the difference between observed residual current (Vr) and predicted wind-driven current (Vc) to a residual current, that is, (Vr -Vc)/Vr shows 56%, 62% at 2 moorings in the Sachon Bay.
