EAGER research: An instrument setup for measuring air-water gas exchange by underwater eddy covariance in shallow-water marine systems

该项目要求资金用于设计、建造和测试一种新的仪器装置，该装置将允许测量浅水海洋环境中的空气-水-气体交换。这一努力将使大量在生态系统研究中使用气体交换估算的水生科学家受益。此外，本科生和研究生将接受使用复杂仪器进行高频数据采集和分析项目中产生的“大数据”的培训。PI将设计、建造和测试一种新的仪器装置，该装置将允许在浅水海洋环境中应用这种新的水生涡流相关技术。这将通过在空气-水界面下方应用他们的水涡相关技术来测量空气-水气体交换来实现。如果成功，新的仪器设置将显著提高浅水海洋系统气体交换测量的准确性，同样重要的是，提高这些测量的时间和空间分辨率。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

The PI's requests funding to design, construct, and test a new instrument setup that will allow measurements of air-water gas exchange in shallow-water marine environments. This effort will benefit a large and broad group of aquatic scientists who use gas exchange estimates in their ecosystem studies. In addition, undergraduate and graduate students will be trained in high-frequency data acquisition with complex instruments and analysis of "big data" produced within this project.The PI's will design, construct, and test a new instrument setup that will allow this new application of the aquatic eddy covariance technique in shallow-water marine environments. This will be accomplished by applying their aquatic eddy covariance technique right below the air-water interface to measure air-water gas exchange. If successful, the new instrument setup will significantly improve the accuracy of gas exchange measurements for shallow-water marine systems, and as important, enhance the temporal and spatial resolution of these measurements.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
