CAREER: A Research and Education Plan for Advancing Ocean Carbon Research through Laser-Based Sensors

这项研究将通过开发一种新的仪器来测量溶解的无机碳，从而解决海洋遥感的关键挑战。这将加强对海洋二氧化碳系统的研究，因为它在气候变化、海洋酸化和生物过程中的作用具有全球重要性。将为5年级和6年级的女孩开发一个“海洋工程和科学学院的女孩”。这项研究将包括本科生、初中和高中教师以及研究生的不同受众。这些努力旨在促进工程和海洋科学/工程领域的多样化。这项研究的总体范围是开发一种能够在各种海洋平台上进行测量的溶解无机碳传感器。研究假设是，传统上用于大气传感的基于红外激光的光谱技术可以用于高灵敏度、易于部署、但成本低的传感器，以满足海洋科学的关键需求。将设计一种基于近红外激光的小型传感器来测量二氧化碳。通过这种传感器的包装，可以部署到1000米深的地方。将先进的分析技术从实验室带入深海将有助于缩小现场传感的关键差距。

This research will address critical challenges for oceanographic sensing by developing a new instrument to measure dissolved inorganic carbon. This will enhance the study of the ocean carbon dioxide system, which is of global importance for its role in climate changes, ocean acidification, and in biological processes. A "Girls in Ocean Engineering and Science Institute," for 5th and 6th grade girls will be developed. A diverse audience of undergraduate students, middle and high school teachers, and a graduate student will be included in the research. These efforts aim to contribute to diversifying the fields of engineering and ocean science/engineering.The overall scope of this research is to develop a dissolved inorganic carbon sensor capable of measurements on a variety of oceanographic platforms. The research hypothesis is that infrared laser-based spectroscopic techniques traditionally used for atmospheric sensing can be utilized for highly sensitive, easy to deploy, yet low cost sensors to fill a critical need in ocean science. A small, near-infrared laser-based sensor will be designed for the measurement of carbon dioxide. Through the packaging of this sensor, deployments to depths up to 1000 m will be achieved. Bringing advanced analytical techniques from the laboratory into the deep sea will help to close critical gaps for in-situ sensing.
