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.

这项研究将通过开发一种测量溶解的无机碳来解决海洋传感的关键挑战。这将增强对海洋二氧化碳系统的研究，这对于其在气候变化，海洋酸化和生物过程中的作用而言至关重要。将开发一个“海洋工程与科学研究所的女孩”，为五年级和六年级的女孩开发。研究中将包括各种各样的本科生，中学和高中老师以及研究生的观众。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学平台上进行测量的溶解的无机碳传感器。研究假设是，基于红外激光的光谱技术传统上用于大气传感，可用于高度敏感，易于部署，但成本低的传感器来满足海洋科学的关键需求。将设计一个小的，近红外激光的传感器，用于测量二氧化碳。通过该传感器的包装，将实现最高1000 m的深度。将实验室的先进分析技术带入深海将有助于弥合临界差距以进行原位感应。
