This preliminary study conducted at the Bikini
Atoll investigated the variation of salt cdOhcentration
in the first 300 ft of atmosphere by collection on
specially developed silver dichromate reagent films. For
a 10-knot wind maximum concentration appeared to exist
at 50 to 75 ft above Mean Low Water Springs, with the
possibility of a second maximum somewhere above 300 ft.
Preliminary size-frequency counts showed a bimodal
