【 摘 要 】

Better understanding the surface circulation in the marine environment is pertinent to the preparedness of pollution response and maritime safety. In the spring of 2012, two GPS surface drifters were deployed off the Minjiang River Estuary to study the surface circulation near the southwestern East China Sea. One drifter followed the China Coastal Current and the other one joined the Taiwan Warm Current. Classical harmonic analysis technique was employed to analyse the current velocities derived from the trajectories of these two drifters. M2 tidal component is dominant in the tidal current spectrum. The residual currents obtained from these 2 drifters agree very well with the previous studies.
