Abstract
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.
