CAREER: Chemical Sentinel--A Mass Spectrometer Payload for AUV Gliders

PI申请资金用于开发一种超紧凑的质量，用于在AUV滑翔机上进行高耐力操作。质谱仪将针对AUV滑翔机进行优化，并能够识别和量化大气、地质和生物衍生气体（甲烷、氮、氧、二氧化碳、硫化物等）以及许多低至十亿分之一的人为污染物。它将适合在一个滑翔机有效载荷体积和低操作。在多个AUV滑翔机上进行这些质谱仪的现场操作，将能够对瞬态化学现象进行天气性评估，如深水上升流、温室气体循环、赤潮以及地震事件、风暴或人类活动引起的化学物质脉冲释放。作为概念验证，PI将把质谱仪集成到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带附近的水柱化学。这项工作将影响PI？美国正在进行仪器仪表开发、自主机器人和实时环境监测方面的研究。本提案的目标是：1)开发一种具有成本效益的ms滑翔机技术，用于测量与海洋地下水体中氮、氧和碳的生物地球化学循环有关的溶解气体变化；2)通过在新英格兰沿海环境中部署这项技术，然后在大西洋大陆架断裂的远程横断面上部署，从而验证NSF的新观测手段？s OOI和其他海洋观测项目；3)将该研究计划整合到基础广泛的学生课程中，以提高工程和科学素养。更广泛的影响：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经历。如今的学生常常被实际操作的工程项目和分析近实时数据流的机会所激发。这个项目提供了这两种途径，并向学生介绍实地工作和海上探险。PI很好地将他的研究整合到广泛的教育计划中。该项目旨在为八年级、高中、本科和研究生阶段的学生提供广泛的STEM课程和积极的学习经验。就更广泛的影响而言，该提案最引人注目的一个方面是卡米利计划与那些为经济弱势和代表性不足的初高中学生提供服务的学校密切合作。通过支持高中项目的“教老师”方法，PI将扩大他的影响力，将高质量的STEM教育带给更多的学生，而不是他自己。PI还将为本科生和研究生提供教育和培训活动。

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.
