Underwater Flow Visualization Methods in the Upper Layer of the Ocean.
Abstract
A unique approach to measuring shear in the ocean has been developed. The approach involves dye tracing to determine the presence and location of shear in water velocity profiles and underwater photography as the data acquisition technique. Subsequent application of photogrammetric techniques is shown to be feasible and puts the observations on a quantitative footing. The advantage of underwater flow visualization over conventional (free-fall) shear measurements is that the result provides graphic evidence of fluid motion and its subsequent evolution. This approach should lend itself to both new and/or improved models of the upper ocean. (Author)
