| Outline of Final Research Achievements |
We carried out a scientific project named “Biopause” using JAXA’s scientific balloons in order to grasp the dynamics of biological flux in the stratosphere, i.e. the lower middle atmosphere, comprehensively. Our first balloon experiment was conducted on June 8, 2016 and collected aerosol particles in the stratosphere using a newly developed descending inertial impactor. We estimated the number density of the stratospheric microbes including the unculturable ones for the first time in the world. In this paper, we summarize of the balloon experiment and the initial results of the sample analysis.
