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测量溶解无机碳的新仪器来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，因为海洋二氧化碳系统在气候变化、海洋酸化和生物过程中的作用具有全球重要性。另外，还将设立以5、6年级女生为对象的“海洋工程科学学院”。研究对象包括本科生、初高中教师和一名研究生。这些努力旨在促进工程和海洋科学/工程领域的多样化。本研究的总体范围是开发一种能够在各种海洋学平台上测量的溶解无机碳传感器。该研究的假设是，传统上用于大气传感的红外激光光谱技术可以用于高灵敏度、易于部署、低成本的传感器，以满足海洋科学的关键需求。一个小型的、基于近红外激光的传感器将被设计用于测量二氧化碳。通过该传感器的封装，可实现深度达1000米的部署。将先进的分析技术从实验室引入深海将有助于填补原位传感的关键空白。

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.
