Abstract : The goal of this research is to gain a better understanding of the processes affecting the near-surface' flow in marine surface layer. The first objective is to improve our understanding of flux profile relationships over the ocean using our mean and flux measurements and the TKE budget equation. This has involved an investigation of the applicability of similarity theory to over-ocean% measurement in order to determine these functions and their proportionality factors. The result of this investigation have shown that the turbulence statistics are similar to those computed over land as long as one is well above the wave boundary layer (WBL). The second objective is to gain a better understanding of the role that stress/wave interaction plays in these processes. The measurement of these profiles in both shallow water and open-ocean settings is allowing us to develop dimensionless functions that are valid anywhere in the constant flux layer. The results of this research that the behavior of the turbulence in the WBL is strongly affected by the wave induced flow. The height of the WBL can be a substantial portion of the surface layer depending on the wave state.
