Instrumentation for the Measurement of Bubble Size Distributions in the Ocean Surface Layer

9529808梅尔维尔向斯克里普斯海洋学研究所海洋物理实验室提供资金，以开发和测试用于测量破碎波下海洋表层夹带空气和气泡尺寸分布的仪器。 海洋表层气泡在气-气传输、气溶胶生成、生物过程和表层声学中起着重要作用。 实验室数据和初步的现场数据表明，破碎波夹带的空气可能是动态的重要通过对浮力所做的工作。 该仪器将是一个宽带（2kHz-200 kHz）系统，用于通过在0.1 - 1 m的路径长度上反演声速和衰减的直接测量值来现场测量表层中的气泡尺寸分布。 研究将分为两个阶段，实验室开发和测试阶段，然后是现场仪器和测试阶段。

9529808 Melville Funding is provided to the Marine Physical Laboratory at Scripps Institution of Oceanography to develop and test instrumentation for measuring entrained air and bubble size distributions in the ocean surface layer beneath breaking waves. Bubbles in the ocean surface layer play an important role in air-gas transfer, in the generation of aerosols, in biological processes, and in the acoustics of the surface layer. Laboratory data and preliminary field data suggest that air entrained by breaking waves may be dynamically significant through the work done against buoyant forces. The instrument will be a broad band (2kHz -200kHz) system for in situ measurements of the bubble size distribution in the surface layer by inverting direct measurements of sound speed and attenuation over path lengths of 0.1 - 1m. The research will be split into two phases, a laboratory development and testing phase, followed by a field instrument and testing phase.
