Measurements of Controlling Factors for Air-Sea Fluxes with High-Resolution Ocean Surface Sensors

P.I. WardProposal: 0241834 P.I.建议开发一种分析仪器来研究海气交换。海气相互作用分析器（ASIP）将配备传感器来测量温度、电导率、湍流速度、氧气和生物物种的丰度。测量将局限于海洋的10米以上，重点是表层。ASIP将是完全独立的，并且能够在部署期间创建向上上升的自主配置文件。这项工作的目标集中在海洋表面的物理、化学和生物过程之间的密切相互作用。该仪器将大大提高对海气交换的科学认识，由于温室气体的积累及其对未来气候的影响等因素，海气交换具有深远的社会影响。如果成功，使用该仪器收集的数据将有助于阐明海洋在吸收二氧化碳方面的作用。准确了解气体交换对于监测沿海地区、河流、湖泊和河口等生态系统也很重要，因为需要这些数据来确定生态系统参数，如生态系统净产量和初级总产量。

P.I. WardProposal: 0241834The PIs propose to develop a profiling instrument for the study of air-sea gas exchange. The Air-Sea Interaction Profiler (ASIP) will be equipped with sensors to measure temperature, conductivity, turbulent velocity, oxygen, and the abundance of biological species. Measurements will be confined to the upper 10 m of the ocean, with a focus on surface layers. ASIP will be completely self-contained and will be capable of making upwardly-rising, autonomous profiles during deployment. The objectives of this work focus on the close interplay between physical, chemical and biological processes at the ocean surface. This instrument will significantly enhance the scientific understanding of air-sea gas exchange, which has far-reaching societal ramifications due to factors such as the buildup of greenhouse gases and their affect on future climate. If successful, the data collected using this instrument will help elucidate the role of the ocean in absorbing CO2. Accurate knowledge of gas exchange is also important for monitoring ecosystems such as those in coastal regions, rivers, lakes and estuaries, as these data are required for determining ecosystem parameters such as net ecosystem production and gross primary production.
