This study will examine physical processes associated with fronts that develop off a coastline point in San Luis Obispo Bay, at the transition of zones exposed to and protected from winds. Information for the study will be derived from measurements of flows, temperature, salinity, and dissolved oxygen obtained from instruments carried on a ship and fixed to the bottom of the ocean. These data will be supplemented by computer model results at different spatial scales, able to resolve the fronts. Additionally, the processes at fronts will be compared to theoretical considerations. The study will suggest ecological implications of the physical processes that generate and dissipate the fronts. The project will support early-career scientists and will recruit historically underserved students. It will generate graphic art related to the project’s findings that will be displayed in an aquarium and used for outreach activities. The proposed work has the goal of examining cross-shelf submesoscale exchange processes associated with persistent thermal fronts downstream of topographic features in an upwelling bay, concentrating on the influence of sea breezes. The goal will be addressed with coordinated high-resolution measurements of turbulent mixing (surveys and moorings of hydrography, velocity and microstructure profiles) together with high-resolution modeling efforts. The study focuses on a frontal feature in a bay, San Luis Obispo Bay, that is impacted by hypoxia and algal blooms. Biologically relevant measurements (notably DO) will enable examination of the biological implications of the proposed cross-front exchange mechanism. The primary dynamical mechanism that will be evaluated at the cross-front exchange is the role, and validity, of the turbulent thermal wind balance. As broader impacts, the study will involve four researchers from different institutions. It will provide measurements of dissolved oxygen and will include particle-tracking calculations for larval connectivity. The project will support two early-career researchers, will adopt a field code-of-conduct and will recruit students from ‘diverse non-PhD granting institutions.’ Results will be portrayed in graphic art with descriptions in English and Spanish, to be included in a local aquarium and used in various outreach efforts.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.

这项研究将检查与在圣路易斯·奥比斯波湾（San Luis Obispo Bay）海岸线上发展的前线相关的物理过程，在暴露并免受风能的区域过渡时。该研究的信息将来自于从船上携带并固定在海底的仪器中获得的流量，温度，盐度和溶解的氧气的测量。这些数据将通过不同的空间尺度上的计算机模型结果补充，能够解决前线。此外，将前部的过程与理论考虑相提并论。该研究将表明产生和消散前部的物理过程的生态意义。该项目将支持早期的科学家，并将招募历史上服务不足的学生。它将生成与该项目的发现有关的图形艺术，该发现将在水族馆中显示并用于外展活动。拟议的工作的目的是检查与上升湾的地形特征下游持续的热线前沿相关的跨架子尺度交换过程，专注于海风的影响。该目标将通过协调的高分辨率测量（水文和系泊，速度和微观结构概况）以及高分辨率建模工作的协调高分辨率测量。该研究的重点是圣路易斯·奥比斯波湾（San Luis Obispo Bay）海湾的额叶特征，该特征受到缺氧和藻类血液的影响。生物学相关的测量（尤其是DO）将能够检查拟议的跨前期交换机制的生物学意义。将在跨前交换中评估的主要动态机制是湍流热风平衡的作用和有效性。随着更广泛的影响，该研究将涉及来自不同机构的四名研究人员。它将提供溶解氧的测量，并包括用于幼虫连接性的粒子跟踪计算。该项目将支持两名早期研究人员，将采用现场守则，并将招募“多样化的非PHD授予机构”中的学生。结果将在图形艺术中描绘，其中包括英语和西班牙语的描述，将包括在当地的水族馆中，并将其用于各种外交。这些奖项反映了NSF的合法任务和范围的依据，该奖项的范围是众所周知的，这是众所周知的，其范围是依据的，该奖项的范围是依据的，该奖项的构建是依据的，该奖项是依据的，这是依据的范围。 标准。
