A Field Study of Oceanic Turbulent Horizontal Diffusion.

Richardson's "four-thirds law" of horizontal diffusion was tested using aerial photography as a data gathering technique. Plywood floats and current crosses suspended both near the surface and at nine feet were used as diffusers. The scales investigated ranged from 10 to 525 meters. The investigation was conducted in 36 fathoms of water, 3000 meters from the nearest land in Monterey Bay, California. Stommel's (1949) method of analysis was used. The results indicate' a clear dependence of diffusion on diffuser weight and lend some evidence to Robert's (1961) theory of turbulent diffusion, in that the diffusion increases more rapidly with scale than proposed by Richardson (1926). This conclusion is supported by the use of confidence limits upon the data.
