Bubble Creation Rates From Breaking Wave Noise

破碎波噪声产生气泡的速度

基本信息

项目摘要

Small-scale transfer processes between the ocean and atmosphere are central to determining weather and climate. During moderate to strong wind speeds the wind-driven ocean wave field entrains large numbers of bubbles thought to be important for a number of transfer mechanisms, including bubble-mediated CO2 transport and the production and biological enrichment of marine aerosols. Despite the importance of bubble-mediated processes very little open ocean data exists on bubble creation rates and the present time there is no reliable method for obtaining these data in the field. This project explores the idea of using the underwater ambient noise to estimate bubble entrainment rates at the air-sea interface by breaking wind waves. The immediate goal of the proposed experiments is to transition an existing wave noise model developed for single plunging laboratory breakers to wind-driven spilling breakers. The primary questions are: 1) Can the existing wave noise model accurately reproduce the noise from individual spilling breakers over a variety of energetic scales? 2) Can the noise from an ensemble of simultaneous spilling breakers be reproduced? 3) Can bubble creation rates, inferred from breaking wave noise, be reconciled with independent estimates of bubble creation rates made during the course of the experiment?These questions will be addressed with a series of laboratory studies with spilling breakers in a wind-wave channel. The noise of individual spilling breakers within a defined study volume will be monitored with hydrophone arrays and video cameras, and correlated with physical measurements of the wave and entrained bubble plumes. The primary plume characterization will be bubble size distributions measured with an array of fiber optic probes. Measurements will also be made of the noise field from simultaneous multiple spilling breakers. Tank reverberation will modify the measured wave noise and will be compensated for using a method successfully applied to earlier wave channel measurements. Wave noise measurements will be compared with model calculations of wave noise based on the measured physical properties of individual spilling breakers.Broader Impact. The experiment and data analysis will include the participation of undergraduate interns from UCSD and the SIO summer research fellowship program. These programs sponsor students from around the country to gain hands-on experience in oceanography. A post-doctoral scholar will be employed to manage the primary experiment. The results of the proposed research are likely have broad impact in the field of air-sea exchange processes during moderate to strong wind speeds, particularly those associated with air sea gas transfer of CO2 and marine aerosol production. These processes are ultimately tied to climate dynamics.
海洋和大气之间的小规模转移过程对于确定天气和气候至关重要。在中度到强风速期间,风向的海浪田招募了大量气泡,这对于多种转移机制很重要,包括气泡介导的二氧化碳运输以及海洋气溶胶的生产和生物富集。尽管气泡介导的过程的重要性很少,但对于泡泡的创建率很少,目前没有可靠的方法来获取这些数据在现场。 该项目探讨了使用水下环境噪声通过打破风波在空气海接口处估算气泡夹带率的想法。提出的实验的直接目标是转变针对单个跌落实验室断路器开发的现有波浪噪声模型,以使风向溢出的断路器。主要问题是:1)现有波浪噪声模型是否可以通过各种能量尺度准确地重现单个溢出断路器的噪声? 2)可以再现同时溢出断路器的合奏中的噪音吗? 3)可以通过在实验过程中对气泡创造率的独立估计来核能,从而通过一系列的实验室研究来解决这些问题,并与风波通道中的溢出破坏者溢出,可以解决这些问题的独立估计。定义的研究量内的单个溢出断路器的噪声将通过水文阵列和摄像机进行监测,并与波浪和夹带的气泡羽相关。主要的羽状表征将是用光纤探针阵列测量的气泡尺寸分布。还将通过同时发生多个溢出断路器来对噪声场进行测量。储罐的回响将修改测得的波噪声,并通过成功应用于早期的波道测量值的方法来补偿。将根据单个溢出断路器的测量物理特性(Boader撞击)将波噪声测量与波噪声的模型计算进行比较。实验和数据分析将包括UCSD的本科实习生和SIO Summer Research奖学金计划的参与。这些计划赞助来自全国各地的学生,以获得海洋学的动手经验。博士后学者将被用来管理主要实验。拟议的研究的结果可能在中等至强风速期间,尤其是与二氧化碳和海洋气溶胶生产的空气海气转移相关的空气交换过程领域具有广泛的影响。这些过程最终与气候动态有关。
