An award is made to the California Institute of Technology and other collaborating organizations including Providence College, Roger Williams University and the University of Texas at Austin to do research and development of a new diver-operated technology to measure key biological and physical processes that affect the health of the ocean and the organisms therein. The ability to conduct science directly in the ocean environment will be a unique national capability that will transform our understanding of the ocean and can potentially enable prediction of adverse impacts on industries such as fishing and coastal tourism. The project will advance the study of marine biology by extending previous laboratory research into more realistic experiments in the field. Importantly, the technology developed during this project will be made available free-of-charge to other U.S. researchers through a loan program developed and tested under prior NSF support. A small business will collaborate with the researchers toward low-cost manufacturing of the technology. The project will support a diverse workforce through the hiring and training of a full-time graduate student and summer students recruited through a program of targeted research opportunities for underrepresented students. These researchers will conduct laboratory and field work at the Marine Biological Laboratory in Woods Hole, MA, exposing them to front-line field research.Knowledge of aquatic animal ecology depends upon accurate measurement of individual organisms for critical processes such as feeding, behavior, and associated fluid motions. Imaging of these interactions has yielded important advances in the understanding of these processes, but has depended primarily upon the controlled conditions of the laboratory. Laboratory conditions allow advanced optical configurations to provide high spatial and temporal resolution moving images within highly controlled conditions. However, these same controlled and defined conditions may also inadvertently create artificial environments that affect the outcome of natural process measurements. The goal of this research is to enable in situ measurements that combine novel daytime particle image velocimetry (PIV); high-resolution, collimated brightfield imaging, and three-dimensional image holography. This new technology will enable (1) direct quantification of complex processes, such as feeding and swimming in turbulent flows under variable lighting conditions, (2) detailed field measurements of animals that are important in the environment but comparatively intractable for controlled laboratory studies, and (3) field confirmation of laboratory data on processes such as predator-prey interactions.

向加利福尼亚理工学院和其他合作组织颁发了奖励，包括普罗维登斯学院，罗杰·威廉姆斯大学和德克萨斯大学奥斯汀分校，以研究新的潜水技术的研究和开发，以衡量影响海洋及其生物体健康的关键生物学和物理过程。直接在海洋环境中进行科学的能力将是一种独特的国家能力，它将改变我们对海洋的理解，并有可能预测对捕鱼和沿海旅游业等行业的不利影响。该项目将通过将先前的实验室研究扩展到该领域的更现实的实验中来推进海洋生物学的研究。重要的是，该项目期间开发的技术将通过在先前的NSF支持下制定和测试的贷款计划免费向其他美国研究人员提供。小型企业将与研究人员合作，以实现该技术的低成本制造。该项目将通过招聘和培训一名专职研究生和夏季学生通过针对人为代表性不足的学生的有针对性的研究机会招募的全职研究生和夏季学生来支持多样化的劳动力。这些研究人员将在马萨诸塞州伍兹霍尔的海洋生物实验室进行实验室和现场工作，使它们暴露于前线现场研究。水生动物生态学的知识取决于对单个生物的准确测量，以在诸如喂养，行为和相关的流体运动等关键过程中对单个生物体进行测量。这些相互作用的成像在理解这些过程方面取得了重要的进步，但主要取决于实验室的受控条件。实验室条件允许高级光学配置在高度控制条件下提供高空间和时间分辨率移动图像。但是，这些相同的受控条件也可能无意间创造人工环境，影响自然过程测量结果。这项研究的目的是实现与新型白天粒子图像速度法（PIV）结合的原位测量。高分辨率，准确的Brightfield成像和三维图像全息图。这项新技术将使（1）直接量化复杂过程，例如在可变的照明条件下的湍流中进食和游泳，（2）对环境中重要的动物的详细现场测量值，但在受控实验室研究中相对棘手，（3）（3）诸如捕食者 - 捕食互动等实验室数据的现场确认。
