The atmospheric bioaerosol was sampled at Syowa Station using tethered balloon, directly. The bioanalysis of a part of samples was starting. We experienced the direct sampling and bio-analysis of bioaerosols in yellow dust (KOSA) using the bioaerosol sampler which was developed on our own terms, a tethered balloon, and an airplane over Japan and China (Kobayashi et al., 2008). More than sixty strains were isolated as atmospheric bioaerosol over Dunhuang City in China and Suzu City in Japan using separated culture method and metagenomic method. The study of atmospheric bioaerosol over the Antarctic will be focused on because it is attracting attention to find the microorganism in the Antarctic ice cores, investigate the long-range transport of atmospheric bioaerosol, and be starting the worldwide bioaerosol observations. To apply our previous methods in the study on KOSA bioaerosol, the direct sampling and bio-analysis of atmospheric bioaerosol over the Antarctic will be tried. The results and finding of atmospheric bioaerosol over the Antarctic will be establish the strong and important impacts to not only biogeography, ecology, history of the Earth, theory of evolution, influence of health, ice-forming nucleus, and global long-range transports of atmospheric bioaerosols, but also investigation on ecosystem in the sky.
