Using the data acquired with Microstructure Profiler MSS60 during the Comprehensive Survey and Evaluation in Chinese Nearshore Waters, turbulent kinetic energy dissipation rate and diffusivity in three seasons between 2006 and 2007 are estimated in the southern Yellow Sea. Our results reveal that mixing tends to be intensive in the coastal region where water is well-mixed. Away from the coast, mixing become more intensive in the near-surface and bottom layers than in the layers in-between. By combing the in situ observations, we suggest that mixing in the Yellow Sea is controlled by both tide and wind. Wind determines the strength of mixing in the upper layer, whereas tide mainly affects bottom mixing.
