Intercomparison of Techniques for the Measurement of Air-Sea Gas Flux

该项目将比较三种侧重于二甲基硫醚（DMS）的海气交换的技术，以帮助评估该领域通量测量的实用性和准确性。准确测量二甲硫醚通量对于估计大气中还原硫的海洋来源和计算海洋对CO2的吸收非常重要。这项研究对气候变化研究很重要，因为二甲基硫醚可以导致硫酸盐气溶胶，而硫酸盐气溶胶又可以导致云的形成。私家侦探将使用梯度通量原位方法来测量DMS通量，并将其结果与荷兰北海高度仪器化平台上其他研究人员使用的几种涡动相关方法进行比较。

This project will intercompare three techniques that focus on air-sea gas exchange of dimethyl sulfide (DMS) to help evaluate the utility and accuracy of flux measurements in the field. Accurate measurements of DMS flux are important in estimating the oceanic source of reduced sulfur to the atmosphere and calculating the uptake of CO2 by the oceans. This research is important for climate change research since DMS can lead to sulfate aerosols that in turn can lead to cloud formation. The P.I. will use a gradient flux in-situ method to measure DMS flux and compare their results with several eddy correlation methods being used by other researchers from a highly instrumented platform in the North Sea off the Netherlands.
