Abstract

地球生命圏の上端biopause、あるいは地球/地球外間の生命の流入/脱出の有無を確認することは、生命の普遍性や起源、進化､分布を理解する上で非常に重要である。地球/地球外間の生命の流入/脱出の有無を確認する最も直接的な鍵は地球中層大気での生物分布にある。我々は中層大気中での微生物の動態を包括的に理解するため、JAXA（宇宙航空研究開発機構）の大気球を用いた成層圏微生物採取実験（Biopause プロジェクト）を行っている。2016 年度に行った第一回目の大気球実験では、新規開発した降下式インパクター型試料採取装置を用いた、成層圏微粒子の採取に成功した。また、培養できないものも含めた成層圏微生物数密度の上限値を世界で初めて観測することに成功した。本稿では、第一回目の大気球実験の概要と初期分析の結果を報告する。, The location of 'biopause', the upper boundary of the biosphere, and the biological flux across the biopause on Earth are the key to understand the universality and distribution as well as the origin and evolution of life in the universe. The most direct information to elucidate the biopause is the distribution and dynamicity of life in the middle atmosphere. 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 the balloon experiment and the initial results of the sample analysis., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1730017002, レポート番号: JAXA-RR-17-007

Abstract

Abstract: The shock-induced decarbonation of non-porous calcite was investigated in an open system over a wide range of peak shock pressures using a two-stage light gas gun and a quadrupole mass spectrometer. We developed a new experimental technique that avoids chemical contamination from the acceleration gas used in the gun. High-speed imaging and spectroscopic observations were conducted simultaneously to investigate the validity of the experimental procedure. The decarbonation efficiency along the Hugoniot curve changed at around 50GPa—the approximate incipient decarbonation pressure predicted by the previous theoretical studies. Decarbonation, albeit at a low efficiency, was detected at pressures below the 50GPa threshold, as observed in previous experimental studies, possibly as a result of energy localization due to a process like shear banding. A simple theoretical model for shock-induced decarbonation during isentropic release was constructed based on the entropy method and the lever rule, assuming the experimental conditions. The predicted amount of released CO2 as a function of the peak shock pressure agreed well with the experimental results at pressures exceeding 50GPa, strongly suggesting that the amount of shock-induced CO2 gas was determined only by the shock-induced entropy gain and by the entropies for incipient and complete decarbonation at the ambient pressure. In future experiments, the new method will be used for quantitative measurements of the chemical composition of impact-induced gases derived from other solid materials. The proposed method is useful in determining the peak shock pressure required for vaporization/devolatilization of geologic materials and for estimating the final chemical composition of impact-induced vapor clouds.
