Abstract
The method of determining the eddy diffusivity over the open ocean either from profiles of the average electric filed or from average values of space charge and electric field measured near the sea surface is discussed. Recent measurements of atmospheric electric variables and meteorological parameters off the east coast of Barbados make it possible to compare values of diffusivity calculated by the atmospheric electric method with values obtained from the bulk aerodynamic method. The results of this comparison show that the atmospheric electric method holds considerable promise under conditions set forth in this paper. The relationship between fluctuations in the electrical variables and fluctuations in the air velocity within the electrical boundary layer is discussed.
