This EAGER project will provide an assessment of the potential use of a high resolution proton transfer time of flight mass spectrometer (PTR-TOFMS) for eddy covariance air/sea gas flux measurements. The composition and rates of emissions of volatile organic compounds from the sea surface are poorly known, which is in large part due to the lack of suitable instrumentation for measuring such fluxes. The PTR-TOFMS will be deployed under field conditions aboard the R/V Knorr in the North Atlantic Ocean. If successful, this will demonstrate the viability of the approach to future field programs. The project may also result in the first broad-spectrum analysis of fluxes of volatile organic compounds emanating from a highly productive oceanic region. This could provide access to new tracers for air/sea gas exchange and insight into the precursors of secondary marine organic aerosols. This project will provide support for a post-doctoral researcher, as well as involve at least one undergraduate student who is participating in the institution's REU site program.

这一急切项目将评估高分辨率质子转移飞行时间质谱仪(PTR-TOFMS)用于涡动协方差大气/海洋气体通量测量的可能性。人们对海面挥发性有机化合物的组成和排放速率知之甚少，这在很大程度上是因为缺乏测量这种通量的适当仪器。PTR-TOFMS将在北大西洋R/V Knorr号上的现场条件下部署。如果成功，这将证明这种方法在未来实地项目中的可行性。该项目还可能导致对来自高生产力海洋区域的挥发性有机化合物通量进行首次广谱分析。这可为大气/海洋气体交换提供新的示踪剂，并深入了解次生海洋有机气溶胶的前体。该项目将为一名博士后研究员提供支持，并至少有一名本科生参与该机构的REU现场项目。
