Outline of Final Research Achievements

Volatile Organic Compounds (VOCs) are important trace gases that act as a fuel of photochemistry in the troposphere. The oceans play a key role in controlling a global budget of VOCs either as a source or a sink. Recent technological advancement enables us to make observations of seawater concentrations and air-sea exchange rate of VOCs. However, there is still a large uncertainty in our understanding of the role of global oceans, due to very limited observations. We customized a proton transfer reaction - time-of-flight mass spectrometer, and coupled with an air-sea equilibrator that can be deployed at a variety of marine observation platforms. The system was tested on a ship and overall evaluation was made. This will enable us to make systematic observations of VOCs dissolved in the ocean surface with a variety of marine platforms including research and commercial vessels.

Academic Significance and Societal Importance of the Research Achievements

海洋は、放出源または吸収源として、揮発性有機化合物(VOC)の全球的収支に大きな役割を果たすと考えられている。本研究開発により、質量分析計を海洋観測プラットフォームに搭載した現場観測が可能になり、今後、様々な海域における溶存VOCの系統的観測が可能になるとともに、VOCの収支に及ぼす海洋の役割およびその生物化学プロセスに関する理解を革新的に深まることが期待される。
