Collections of individual submicrometer particles were carried out with a low-pressure impactor on board of ship over the ocean of the Southern Hemisphere in December 1982,February 1984 and March 1984. The collected samples were examined by using a transmission electron microscope in order to investigate the morphological features of individual particles of 0.04-0.1 μm radius, together with the particle number concentrations. Two types of sulfate-containing particles other than sea-salt particles were found in a wide region and were dominant particles of 0.04-0.1 μm radius. The morphological features were quite different from each other. Particles with distinct outline on the collecting surface had the morphological features similar to ammonium sulfate particles and their estimated concentrations varied largely from 5.5 to 72.6(cm)^<-3>. Whereas, particles showing vague outline on the collecting surface were also present in the concentrations ranging from 2.1 to 9.4(cm)^<-3> over the Indian Ocean.
