Over the past two decades, a new spectroscopic technique called laser induced breakdown spectroscopy (LIBS) has been developed and has gained favor for in situ field measurements in hostile environments. The goal of this proposal is to build a LIBS system suitable for deployment on Alvin with pressure cases and interfaces that are Alvin compatible. Once constructed, the PIs will re-validate the laboratory measurements in a test tank. At the end of this phase, they should have a working LIBS system that is compatible with Alvin, and that has been validated in a real water environment. Broader Impacts: The work itself addressing the advancement of the technology and the measurement environment are state-of-the-art research and development. The system configuration and results in this harsh environment will benefit other applications for real-time monitoring, including industrial processes and space exploration. Additionally, the research will lead to several student PhD dissertations, and collaborations among international research teams.

在过去的二十年中，一种称为激光诱导击穿光谱（LIBS）的新型光谱技术得到了发展，并在恶劣环境下的原位现场测量中受到青睐。该提案的目标是构建一个适合在 Alvin 上部署的 LIBS 系统，其压力情况和接口与 Alvin 兼容。一旦建成，PI 将在测试池中重新验证实验室测量结果。在此阶段结束时，他们应该拥有一个与 Alvin 兼容的可用 LIBS 系统，并且已在真实水环境中得到验证。更广泛的影响：解决技术进步和测量环境的工作本身就是最先进的研究和开发。这种恶劣环境下的系统配置和结果将有利于其他实时监控应用，包括工业过程和太空探索。此外，该研究还将产生几篇学生博士论文，以及国际研究团队之间的合作。
