The PI requests funding to develop an integrated imaging system that would concurrently measure the characteristics of submarine seep bubbles/drops and the “structure” of the surrounding ocean water. This work would produce models for bubble fluxes and dispersal that can be useful to researchers working in many different domains. It would contribute to a better understanding of the influence of natural marine hydrocarbon seepage to the hydrosphere and atmosphere is urgently needed to evaluate its importance and contribution, especially these days when global warming and our changing environment is also highly debated in public. This work provides well-structured educational programs with clear methods of assessment. The instrument to be developed through the proposed project has a high potential to foster international and interdisciplinary collaboration, especially if implemented in a marine cabled observatory array like OOI. Given the fundamental challenges and the need of understanding the interaction between the natural seep and its agitated water flow, this proposal is dedicated to developing an innovative imaging system that would near-simultaneously measures the size of drops/bubbles, appearance of the bubble surface, morphological behavior, rise velocity, and discharge, and the three-dimensional velocity of water, turbulent statistics, vortices in the bubble wake, and the characteristics length and time scales in bubble-induced mixing. This new instrument would overcome some key deficiencies in imaging systems currently available to the research community studying submarine seeps.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.

PI要求资金开发一种集成的成像系统，该系统将同时衡量海底渗出气泡/滴和周围海水的“结构”的特征。这项工作将产生用于气泡通量和扩散的模型，这对于在许多不同领域工作的研究人员很有用。迫切需要更好地理解天然海洋烃对水圈和大气的影响，以评估其重要性和贡献，尤其是如今，当全球变暖和我们不断变化的环境在公众中也高度争议。这项工作提供了结构良好的教育计划，并具有清晰的评估方法。通过拟议项目开发的工具具有促进国际和跨学科合作的高潜力，尤其是如果在像OOI这样的海洋有线观察阵列中实施的话。 Given the fundamental challenges and the need of Understanding the interaction between the natural seep and its agitated water flow, this proposal is dedicated to developing an innovative imaging system that would near-simultaneously measure the size of drops/bubbles, appearance of the bubble surface, morphological behavior, rise velocity, and discharge, and the three-dimensional velocity of water, turbulent statistics, vortices in the bubble wake, and the characteristics length and time气泡引起的混合中的尺度。该新工具将克服目前可用于研究潜艇看到的研究社区现有的成像系统中的一些关键缺陷。该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的影响审查标准，通过评估被认为是珍贵的支持。
