英文摘要	High frequency velocity fluctuations were measured by using an acoustic Doppler velocimeter (ADV) in the tidal bottom boundary layer (BBL) of the Yellow Sea (YS) for 25 h. The turbulent kinetic energy dissipation rate and the bottom shear stress were estimated and analyzed. Results show that: (1) in the tidal BBL of the YS, the variations of the dissipation rate and the bottom shear stress during 25 h are (1.8 x 10(-8)-3.4 x 10(-5)) W . kg(-1) and (6.6 X 10(-4)-7.5 x 10(-1)) N.m(-2) respectively, indicating that there are strong dissipations in the tidal BBL of the YS; (2) in the well-mixed tidal BBL, the turbulence is mainly shear-induced locally and the production and dissipation are generally in equilibrium; (3) for the seas where the semidiurnal tidal current is dominant, both the dissipation rate and the bottom shear stress exhibit a strong quarter-diurnal variation; (4) the mean bottom drag coefficient (C) over bar (d)(0.45) is 0.0017 (corresponding (C) over bar (d)(1.00)=0.0015), but it has significant variations (0.0005-0.0082). The mean bottom roughness length is 2.8 X 10(-5) m.
