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

这一RAPID项目将扩大一项广泛的实地实验，旨在确定和量化内（沿海）大陆架上的横向混合和扩散。在他们资助的实验中，Monismith，Stacey，Powell和McManus（项目名称：合作研究-内大陆架上的横向混合和分散）专注于物理垂直和水平混合过程，这些过程驱动了表层和底栖混合层的水平运输，以及中层，高度分层层，生物材料的薄层可以积累。通过结合使用系泊、自主和拖曳仪器，其实验设计侧重于精细的垂直（厘米-米）和水平（米-100米）尺度，测量垂直和水平速度、温度、盐度和密度场以及光学（和声学）特性，以确定浮游生物（浮游植物和浮游动物）的分布。虽然他们的工作主要集中在物理上，但PI对与内大陆架各层相关的发展和水平扩散的生物后果有明确的兴趣。该RAPID奖支持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增加实验能力。通过增加我们的原位Ichthyoplankton成像系统（ISIIS）的采样，由于ISIIS的非常高的光学分辨率能力，浮游生物群落将在视觉上被解析到关键的分类水平。以前从来没有这样的机会耦合非常精细规模的物理力学测量与可比的生物测量。此外，ISIIS的采样能力将使这项工作的细尺度重点也被置于亚中尺度（~ 10-15公里）的空间尺度的角度来看，更广泛的影响这个快速项目的更广泛的影响包括图像分析和数字存档，将产生一个永久的，数字记录的南极标本及其相关的环境数据。这种数据资源的提供将提高科学界分享信息的能力。本研究过程中收集的图像将通过访问UM CSS保存的数据库（通过与主要研究者的沟通和网站（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，重点是跨学科研究：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利用ISIIS数据与PI的实验室相关的生物海洋学的具体研究项目。

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.
