Collaborative Research: Oceanic Application of Laser Induced Breakdown Spectroscopy

为一个概念验证项目提供了资金，以确定采用激光诱导击穿光谱(LIBS)技术在海洋中的深潜器上作业的可行性，并可能应用于大洋中脊的热液喷口系统。将购买一台最先进的ICCD光谱仪，并将分析候选热液喷口材料在液体中的高压测量。这项拟议工作的一个主要成果将是实验室高压下LIBS的表征，从中可以获得重要的仪器参数、现场校准标准和关于LIBS等离子体的基本信息。他们建议测试、验证和记录LIBS系统是否适合从深潜潜水器进行操作。

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.
