Collaborative Research: Oceanic Application of Laser Induced Breakdown Spectroscopy

为概念验证项目提供资金，以确定采用 LIBS（激光诱导击穿光谱）技术在海洋深潜器上运行的可行性，并有可能应用于大洋中脊的热液喷口系统。将购买最先进的 ICCD 光谱仪，并对候选热液喷口材料的液相高压测量进行分析。拟议工作的主要成果将是实验室高压下 LIBS 的表征，从中可以得出重要的仪器参数、原位校准标准以及有关 LIBS 等离子体的基本信息。他们提议测试、验证和记录 LIBS 系统在深潜器上运行的适用性。

Funding is provided for a proof of concept project to determine the feasibility of adapting LIBS (Laser Induced Breakdown Spectroscopy) technique for operation from a deep submergence vehicle in the ocean, with potential application to hydrothermal vent systems at mid-ocean ridges. A state-of-the-art ICCD spectrometer will be purchased and high pressure measurements of candidate hydrothermal vent materials in liquid phase will be analyzed. A major product of the proposed work will be characterization of LIBS at high pressure in the laboratory, from which important instrumental parameters, in situ calibration standards, and fundamental information about LIBS plasmas can be derived. They proposed to test, validate, and document the suitability of the LIBS system for operation from a deep submergence vehicle.
