Collaborative Research: Oceanic Application of Laser Induced Breakdown Spectroscopy

为一个概念验证项目提供了资金，以确定将激光诱导击穿光谱技术用于海洋深潜器操作的可行性，并有可能应用于大洋中脊的热液喷口系统。将购买一台最先进的ICCD光谱仪，并将分析候选热液喷口液相物质的高压测量结果。拟议的工作的一个主要产品将是在实验室中的高压下LIBS的特性，从中可以得到重要的仪器参数，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.
