Size distributions of Aitken nuclei were measured in the middle and western part of the North Atlantic between 38 through 22° N and 36 through 63° W. The apparatus comprised diffusion batteries and an especially designed condensation nuclei counter. The measurements cover the size range from about 3·10-1 through to 1·10-5 cm aerodynamically equivalent particle radius. There are some indications on the trend of particle numbers above 1·10-5 cm but no reliable number distributions. The size spectra were bimodal in the north eastern part of the cruise. Closer to the Caribbean the contribution of very small particles was enhanced and the peaks shifted to larger sizes to a certain extent.
