中文摘要
生物源性挥发性有机化合物(BVOC)在地球系统过程中发挥着关键作用,但人们对BVOC的排放量及其在海洋栖息地产生的机制知之甚少,尽管这些是BVOC排放的潜在热点。本课题的目的是定制一种便携式平衡器入口质子转移反应质谱仪,用于沿海水域BVOC的测量。这将是南半球第一个这样的仪器,它将使我们能够在现场进行高精度测量,这将导致突破性的进步,这将彻底改变我们对沿海环境中BVOC循环及其对全球气候系统影响的理解。
英文摘要
Biogenic volatile organic compounds (BVOC) play a key role in earth system processes but little is known about the amount of BVOCs emitted, and the mechanisms underlying their production in marine habitats, despite these being potential hotspots for BVOC emissions. The aim of this proposal is to custom build a portable equilibrator inlet proton transfer reaction mass spectrometer for measurements of BVOC’s in coastal waters. This will be the first such instrument in the southern hemisphere and it will enable us to make in situ, high-precision measurements which will lead to ground-breaking advances that will revolutionise our understanding of BVOC cycling in coastal environments and their influence on the global climate system.
