Collaborative Research: Oceanic Application of Laser Induced Breakdown Spectroscopy

该项目为概念验证项目提供了资金，以确定将LIBS（激光诱导击穿光谱）技术应用于海洋深处潜水器的可行性，并有可能应用于海洋中脊的热液喷口系统。将购买最先进的ICCD光谱仪，并对液相中候选热液喷口物质的高压测量进行分析。这项工作的主要成果将是实验室高压下LIBS的表征，从中可以推导出重要的仪器参数、原位校准标准和LIBS等离子体的基本信息。他们建议测试、验证并记录LIBS系统在深海潜水器上的适用性。

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.
