✦ Synopsis

Na, CI, SO4, and K were determined in near-ground aerosols on a traverse normal to the coast up to a distance of 6 km from the shore at Caesarea, Israel. Statistically significant power or exponential functions can both express the rate of decrease in concentration with distance from the shore. The larger droplets which were deposited mainly up to 1,500 m were essentially of sea water composition with regard to the major ions. The remaining smaller particles had a relatively larger excess of SO4.

The stormier wind regime during the winter season produced a larger amount of sea spray which was not carried so far inland as the dry season spray. The behaviour of SO4 differs from that of C1 and Na. Local topography has a considerable influence on the distribution and deposition of the airborne salts. The frequency distribution of concentrations at any one station tends to be lognormal.
