The PI requests funding to develop an ultra-compact mass for high-endurance operation onboard an AUV glider. The mass spectrometer will be optimized for operation aboard an AUV glider and will be capable of identifying and quantifying atmospheric, geologic, and biologically derived gases (methane, nitrogen, oxygen, carbon dioxide, sulfides, etc.) as well as many anthropogenic pollutants at levels down to parts-per-billion. It will fit within a glider payload volume and operate at low. In-situ operation of these mass spectrometers onboard multiple AUV gliders will enable synoptic assessment of transient chemical phenomena such as deep-water upwelling, greenhouse gas cycling, red tides, and pulsed releases of chemicals caused by seismic events, storms, or human activity. As proof-of-concept the PI will integrate this mass spectrometer aboard a Slocum electric glider to characterize and persistently monitor water column chemistry in Massachusetts coastal waters and near the New England Shelf Break. This work will leverage the PI?s ongoing research in instrumentation development, autonomous robotics, and real-time environmental monitoring. The objectives of this proposal are to: 1) Develop a cost-effective MS-glider technology for measuring dissolved gas variability relating to biogeochemical cycling of nitrogen, oxygen, and carbon in the subsurface marine water column; 2) Demonstrate this technology via deployments in coastal New England environments, then in long-range transects off the Atlantic shelf break, thereby validating a new means of observation for NSF?s OOI and other ocean observation programs; and 3) Integrate this research program into broad-based student curricula to promote engineering and science literacy.Broader Impacts: The proposed education program will provide exciting learning experiences for students from Middle school ages to graduate school. Today's students are often turned on by hands-on engineering projects and opportunities to analyze near-realtime data streams. This project offers both, plus avenues to introduce students to field work and sea expeditions. The PI is well situated to integrate his research into broad-based educational programs. The PI intends to provide broad-based exposure to STEM curricula and active learning experiences for students ranging from 8th graders, to high school, undergraduate and graduate levels. One of the most notable aspects of the proposal, in terms of the broader impacts, is Camilli's plan to work closely with schools that serve economically disadvantaged and underrepresented students at the middle or high school level. By supporting the 'teach the teacher' approach for the high school program, the PI will extend his reach to bring high quality STEM education to more students more consistently than he can do on his own. The PI will also provide education and training activities for undergraduate and graduate students.

PI要求资金来开发一种超紧凑型质量，用于AUV滑翔机上的高耐力操作。质谱仪将为AUV滑翔机上的操作进行优化，并将能够识别和量化大气、地质和生物来源的气体(甲烷、氮气、氧气、二氧化碳、硫化物等)。以及许多人为污染物，低至十亿分之一的水平。它将适合滑翔机的有效载荷量，并以较低的速度运行。在多架AUV滑翔机上现场操作这些质谱仪将能够对瞬时化学现象进行天气学评估，例如深水上升流、温室气体循环、赤潮以及地震事件、风暴或人类活动导致的化学物质脉冲释放。作为概念验证，PI将把这个质谱仪集成在Slocum电动滑翔机上，以表征和持续监测马萨诸塞州沿海水域和新英格兰大陆架断裂附近的水柱化学。这项工作将利用皮？S正在进行的仪器开发、自主机器人和实时环境监测方面的研究。这项建议的目标是：1)开发一种经济高效的MS-Glider技术，用于测量与海底水柱中氮、氧和碳的生物地球化学循环有关的溶解气体可变性；2)通过在新英格兰沿海环境中部署该技术，然后在大西洋大陆架附近的远程断面上展示该技术，从而验证美国国家科学基金会？S海洋研究所和其他海洋观测计划的新观测手段；以及3)将该研究计划整合到基础广泛的学生课程中，以促进工程和科学素养。广泛的影响：拟议的教育计划将为从中学到研究生院的学生提供令人兴奋的学习体验。如今的学生经常被实际操作的工程项目和分析近乎实时的数据流的机会所吸引。这个项目提供了两种方式，外加向学生介绍野外工作和海上探险的途径。他很适合将他的研究整合到基础广泛的教育项目中。PI打算为从八年级到高中、本科生和研究生的学生提供广泛的STEM课程和积极的学习体验。就更广泛的影响而言，该提案最引人注目的方面之一是卡米利计划与服务于经济困难和代表不足的初中或高中学生的学校密切合作。通过支持高中项目的“教师授课”方法，PI将扩大他的触角，为更多的学生带来比他自己能做的更始终如一的高质量STEM教育。国际和平研究所还将为本科生和研究生提供教育和培训活动。
