Always oceanographers pay attention to layer structure in the sea environment. Creation of layer structures is because of some phenomenons like double diffusion, internal waves, turbulence modular mixing. In this paper with examination of vertical structure of temperature, salinity and density betweenPersian GulfandOmanSeain different seasons, layer structures appear clearly. Also countors of the same physical parameters show the existence of regular structure which prove internal waves resulting from thePersian Gulfand flow into theOmanSea. The exchange flow through the Stait of Hormus results from horizontal density gradient between thePersian GulfandOmanSea. In winter the density ratio ( ) in this nearshore region is a bout 0.7 and in offshore region is 0.2. this shows that in this area, double diffusion forms layer structures which have horizontal variations as well as in the vertical. Coastal topography also seems to affect the double diffusion processes and leads to variations of layering in horizontal directions especially between near and offshore regions .
