1. Introduction Tides and tidal currents are basic motions in the ocean and play an important role in the studies of other ocean dynamics, such as storm surges, internal tides, and circulations ( Munk 1997 ; Xu et al. 2016 ; Cao et al. 2017 ). In continental shelf areas, strong tidal currents can cause intense shear near the seafloor, which finally contribute to intense turbulent mixing ( Heathershaw 1979 ; Liu and Wei 2007 ; Lozovatsky et al. 2008 ; Yoshikawa et al. 2010 ). In boundary

theair-sea interface. In addition to strong turbulence generated by breaking waves, the bubbles will be advectedby Langmuir circulation, fronts, and internal waves(Thorpe 1984a-d) making them useful tracers forstudies of upper-ocean dynamics. Determination of therole bubbles play in these physical processes necessitatesacquisition of profiles of bubble-size distribution as afunction of time and depth. Ideally, such profiles shouldbe acquired remotely so as to avoid interference withthe processes

analyze the effects of surface heat flux and surface ocean mixed layer physics, but observations are not adequate to carry out such extensive diagnostic studies at present. In these cases, simulations from ocean general circulation models (OGCMs) that can accurately simulate SST and MLD may be useful in compensating for the sparseness of the oceanic observations and provide a more comprehensive picture. Most bulk mixed layer models are one-dimensional and assume that the mean temperature and

. 2000 ; Lathrop et al. 2006 , 2014 ). However, aerial photography of surface currents is still an immature observational technique in coastal waters compared with open oceans, where satellite altimetry indirectly provides surface currents under the assumption of geostrophy. In the 1970s, Assaf et al. (1971) observed surface circulation based on aerial photographs of dye distributions, founding small-scale Langmuir cells within a several-hundred-meter square. However, this was a qualitative
