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

智力价值这个快速项目将加强一项广泛的现场实验，旨在识别和量化内(沿海)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(项目标题：合作研究--内陆架的横向混合和扩散)专注于物理垂直和水平混合过程，这些过程驱动表层和海底混合层以及中水、高度分层的层中的水平输送，在那里可以积累薄层生物物质。通过系泊、自主和拖曳组合仪器，它们的实验设计侧重于细垂直(厘米-米)和水平(m-100‘S米)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确定浮游生物(浮游植物和浮游动物)分布的光学(和声学)特性。虽然他们的工作主要集中在物理上，但私人投资机构显然对与内陆架各层相关的发展和水平扩散的生物学影响感兴趣。这一快速奖励从可能受到研究中的混合和扩散特性影响的生物群落的角度支持了实验的额外能力。通过使用我们的原位鱼浮游生物成像系统(ISIIS)进行采样，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分解到关键的分类水平。以前从未有过这样的机会，可以将非常精细的物理机械测量与可比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重点也可以放在亚中尺度(约10-15公里)的空间尺度透视中。广泛影响这一快速项目的广泛影响包括图像分析和数字存档，这将产生浮游标本及其相关环境数据的永久数字记录。这种数据来源的提供将提高科学界共享信息的能力。在本研究过程中收集的图像将提供给科学和教育界，方法是访问即将开发的UM CSS数据库(通过与牵头PI的沟通和一个网站(Ftp)链接)。在教育价值方面，PIS将培养一名博士研究生，重点是跨学科研究：整合海洋科学、计算机科学和工程学。其他研究生和本科生将有机会与国际海洋学研究所的实验室合作，为与生物海洋学有关的具体研究项目利用ISIIS数据。

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.
