RAPID: Application of ISIIS to a multi-instrumented experiment on lateral mixing and dispersion on the inner shelf

智力优势该 RAPID 项目将增强广泛的现场实验，旨在识别和量化内（沿海）陆架的横向混合和分散。在他们资助的实验中，Monismith、Stacey、Powell 和 McManus（项目名称：协作研究 - 内架横向混合和分散）重点研究物理垂直和水平混合过程，这些过程驱动表层和底栖混合层以及中水高度分层层的水平传输，其中薄层生物材料可以在其中积聚。通过结合系泊、自主和拖曳仪器，他们的实验设计侧重于精细垂直（cm-m）和水平（m-100's m）尺度，通过测量垂直和水平速度、温度、盐度和密度场以及旨在识别浮游生物分布（浮游植物和动物）的光学（和声学）特性。虽然他们的工作主要关注的是物理方面，但 PI 对与内架各层相关的开发和水平扩散的生物影响有着明确的兴趣。从可能受到所研究的混合和分散特性影响的生物群落的角度来看，该 RAPID 奖项支持增加实验能力。通过使用我们的原位鱼类浮游生物成像系统 (ISIIS) 添加采样，由于 ISIIS 具有非常高的光学分辨率能力，浮游生物群落将在视觉上解析到关键的分类水平。以前从未有过这样的机会将非常精细的物理机械测量与可比较的生物测量结合起来。此外，ISIIS 的采样能力将使这项工作的精细尺度焦点也能够置于亚中尺度（约 10-15 公里）空间尺度视角。 更广泛的影响 该 RAPID 项目的更广泛影响包括图像分析和数字归档，这将生成浮游生物样本及其相关环境数据的永久数字记录。这种数据资源的可用性将提高科学界之间共享信息的能力。在本研究过程中收集的图像将通过访问 UM CSS 的数据库（通过与主要 PI 的通信和网站 (ftp) 链接）提供给科学和教育界。在教育价值方面，PI将培养一名博士研究生，重点关注跨学科研究：整合海洋科学、计算机科学和工程。其他研究生和本科生将有机会与 PI 实验室合作，利用 ISIIS 数据进行与生物海洋学相关的特定研究项目。

Intellectual MeritThis RAPID project will augment an extensive field experiment aimed at identifying and quantifying lateral mixing and dispersion on the inner (coastal) shelf. In their funded experiment, Monismith, Stacey, Powell, and McManus (Project title: Collaborative Research - Lateral mixing and dispersion on the inner shelf) are focusing on the physical vertical and horizontal mixing processes that drive horizontal transport in the surface and benthic mixed layers, and the midwater, highly stratified layer, where thin layers of biological material can accumulate. Through a combination of moored, autonomous and towed instrumentation, their experimental design is focused on the fine vertical (cm-m) and horizontal (m-100's m) scales through measurements of vertical and horizontal velocities, temperature, salinity and density fields, as well as optical (and acoustic) properties aimed at identifying plankton distributions (both phyto- and zooplankton). While the primary focus on their work is physical, the PIs have an explicit interest in the biological ramifications of the development and horizontal dispersal associated with the various layers of the inner shelf. This RAPID award supports added capacity to the experiment from the perspective of the biological communities likely to be impacted by the mixing and dispersal properties under study. By adding sampling with our In Situ Ichthyoplankton Imaging System (ISIIS), the planktonic community will be visually resolved to key taxonomic levels due to the very high optical resolution capabilities of ISIIS. Never before has there been such an opportunity for coupling very fine-scale physical mechanistic measurements with comparable biological measurements. Moreover, the sampling capabilities of ISIIS will allow the fine-scale scale focus of this work also to be placed into a submesoscale (~ 10-15 km) spatial scale perspective.Broader ImpactsBroader impacts of this RAPID project consist of image analysis and digital archiving that will generate a permanent, digital recording of planktonic specimens with their associated environmental data. Availability of such a resource of data will increase the capacity to share information among the scientific community. Images collected during the course of this study will be available to the science and education community through access to the a database held at the UM CSS (via communication with the lead PI and a Website (ftp) link) to be developed. With respect to educational value, the PIs will train one doctoral graduate student with a focus on interdisciplinary research: integrating marine science, computer science, and engineering. Other graduate and undergraduate students will have the opportunity to utilize ISIIS data for specific research projects relevant to biological oceanography in association with the PI's lab.
