Abstract : The amount of sodium in the air is of interest in the fields of meteorology and agriculture in the discussion of shore phenomena as sources of condensation nuclei. Also, it is of importance in calculating the hazard due to neutron-induced radioactivity produced in the employment of tactical nuclear weapons in coastal areas. In this paper a method is described which will allow samplings of the mass loading of the atmosphere of an hour's duration while twelve hours was previously necessary. This instrument is applied in measuring the salt content above seashores as a function of sea, wind, and microseismic action. It is observed that sea and wind are indicators but that microseismic action gives the best indication of the sodium content. The distribution of exchangeable sodium on various California beaches is studied as well as the time variations of this quantity. An average profile of exchangeable sodium is reported and a means of determining the profile within an order of magnitude from weather data is described. (Author)
