This grant is to support the 2024 Gordon Research Conference (GRC) on Ocean Mixing, as well as the Gordon Research Seminar (GRS) for early career scientists. These will provide a forum to improve the broader community’s understanding of turbulent mixing in the ocean, including the interactions across scales, and practical applications. Ocean mixing has important impacts in many areas of societal relevance, including climate (e.g. ocean heat and carbon uptake, the meridional overturning circulation), weather (e.g. hurricane intensity), pollution (e.g. marine plastics) and ecosystems (e.g. hypoxia). More recently, as the possible role of the ocean in mitigating climate and ecosystem changes is being explored, changes to mixing resulting from ocean renewable energy and influence of ocean mixing on enhanced ocean carbon dioxide removal must also be considered. The 2024 GRC will make the connection between fundamental studies of ocean mixing and these important impacts and applications. The GRC format is designed to generate vigorous discussion and foster new collaborations, stimulating new understanding. The GRC will strengthen the connection between fundamental studies of ocean mixing and applications to societally relevant problems, with consequent benefits to society. The GRC will also foster an inclusive ocean mixing community by promoting new interactions between people working on different aspects, using different approaches, and at varied career levels, through focused discussions and facilitated informal networking activities. The GRS will enable the full participation of early career scientists in this community, contributing to workforce development. NSF support will help to eliminate financial barriers to participation, by supporting attendance of early career scientists and scientists from historically under-represented groups.Ocean mixing, which can loosely be defined as time-variable motion which increases fluxes of tracers above levels set by molecular diffusion, encompasses a wide variety of processes taking place over a large range of scales, from mesoscale geostrophic eddies to isotropic turbulence. Between these scales many different instability processes excite motions which lead to mixing. All these processes, except for the largest mesoscale eddies, occur on scales too small to explicitly simulate in the ocean component of climate models, requiring parameterizations of their impact on tracer fluxes to accurately capture their effect on the large scale ocean. The development of parameterizations requires experts in different aspects of ocean mixing - observations, theory, process simulation, laboratory experiments, regional and climate modeling - to work together. The GRC stimulates this collaboration between scientists using different approaches and focused on different scales, to better understand ocean mixing. The GRS provides a forum for early career scientists to network with their peers and engage in professional development prior to the main conference.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.

这笔拨款用于支持2024年戈登海洋混合研究会议（GRC），以及戈登早期职业科学家研究研讨会（GRS）。这将提供一个论坛，以提高更广泛的社区对海洋湍流混合的理解，包括跨尺度的相互作用和实际应用。海洋混合在许多与社会相关的领域具有重要影响，包括气候（例如海洋热量和碳吸收、经向翻转环流）、天气（例如飓风强度）、污染（例如海洋塑料）和生态系统（例如缺氧）。最近，由于正在探索海洋在减缓气候和生态系统变化方面可能发挥的作用，还必须考虑海洋可再生能源对混合造成的变化以及海洋混合对加强海洋二氧化碳清除的影响。2024年GRC将把海洋混合的基础研究与这些重要影响和应用联系起来。GRC的形式旨在产生激烈的讨论，促进新的合作，激发新的理解。GRC将加强海洋混合的基础研究与应用于与社会有关的问题之间的联系，从而给社会带来好处。GRC还将通过重点讨论和便利的非正式网络活动，促进从事不同方面、使用不同方法和不同职业水平的人们之间的新互动，从而培育一个包容性的海洋混合社区。GRS将使早期职业科学家充分参与这个社区，为劳动力发展做出贡献。NSF的支持将通过支持早期职业科学家和历史上代表性不足的群体的科学家的出席，帮助消除参与的经济障碍。海洋混合可以粗略地定义为使示踪剂的通量高于分子扩散所设定的水平的时变运动，它包括在大尺度范围内发生的各种各样的过程，从中尺度地转涡旋到各向同性湍流。在这些尺度之间，许多不同的不稳定过程激发运动，导致混合。除了最大的中尺度涡旋外，所有这些过程都发生在太小的尺度上，无法在气候模式的海洋分量中明确模拟，因此需要对它们对示踪剂通量的影响进行参数化，以准确地捕捉它们对大尺度海洋的影响。参数化的发展需要海洋混合不同方面的专家——观测、理论、过程模拟、实验室实验、区域和气候模拟——共同努力。GRC刺激了科学家之间的合作，使用不同的方法，关注不同的尺度，以更好地了解海洋混合。GRS为早期职业科学家提供了一个论坛，让他们在主要会议之前与同行建立联系，并从事专业发展。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。
