The study of dynamic biogeochemical processes in the ocean, especially in the deep ocean or near hydrothermal vents, is a daunting challenge and requires the ability to monitor a variety of chemical species in-situ in real time under extreme conditions. Understanding these dynamic processes is critical for our ability to predict and/or mitigate the long term effects of natural and human impacts on the oceans. The propose to develop and demonstrate a prototype ion selective electrode (ISE) sensor array capable of providing simultaneous in-situ real-time measurements of a variety of ionic chemical species at extreme depths and near vent temperatures in the ocean. The proposed sensor array will be based on the ISE sensor array that was designed, built, tested, and successfully used on the surface of Mars as part of the 2007 Phoenix Mars Mission, to analyze for ionic species in an aqueous solution containing a soil sampleThe longer term objective of this initial effort is to enable follow-on research that, with improved detection limits and selectivity, will provide the ocean sciences community with a new tool for in-situ real-time mapping of a broad range of chemical species in seawater. The resulting sensor array device will also be of use to researchers in a variety of related disciplines for studies or monitoring of other bodies of water such as lakes, estuaries, ground water, drinking water, and rivers.Broader Impacts: The development of an innovative research tool to enable in-situ temporal and spatial monitoring of the chemical properties of oceanic waters represents an enormous contribution to the fields of environmental and analytical chemistry. Clearly, this project if successful will enable a charting of ocean circulation, measurements of carbon dioxide levels in the ocean, and studies of the impacts of these on climate change research. The outreach program will engage teachers and students in summer field studies to monitor waters at the mouth of the Charles River in Boston Bay and/or the Delaware Estuary, and the anoxic Delaware Inland Bays. These will provide enormous intangible, yet demonstrable outcomes and impacts of the research. Three graduate students are involved in this project. In addition, the project will provide opportunities for undergraduate student from a broad range of disciplines to participate in the design and development of in situ instrumentation. High-school students will also be involved, through the participation of classrooms to field tests and to a summer field trip, involving the graduate students supported by the project. Public outreach is also mentioned, through the realization of videos by classrooms.

对海洋中的动态生物地球化学过程的研究，尤其是在深海或水热通风孔附近，是一个艰巨的挑战，需要在极端条件下实时监测各种化学物种的能力。了解这些动态过程对于我们预测和/或减轻自然和人类对海洋的长期影响的能力至关重要。提议开发和演示一个原型离子选择性电极（ISE）传感器阵列，能够在极端和海洋中的通风孔中同时提供各种离子化学物种的实时实时测量。拟议的传感器阵列将基于ISE传感器阵列，该阵列是在火星表面设计，建造，测试和成功使用的，作为2007年凤凰MARS任务的一部分，可以分析包含该最初努力的较长努力的水溶液中的离子溶液中的离子物种，并启用了一项新工具，并将其提供一定的新工具，并将其选择开发，并选择了一定的选择。海水中广泛的化学物种的实时映射。所得的传感器阵列设备也将用于研究或监测其他水域（例如湖泊，河口，地下水，饮用水和河流）的各种相关学科的研究人员。BOADER的影响：开发创新的研究工具，以启用对环境的临时和空间监测，以启用了环境的贡献，并贡献了对海洋化学的贡献的代表。显然，如果成功，该项目将能够绘制海洋循环图表，测量海洋中的二氧化碳水平以及对这些对气候变化研究的影响的研究。外展计划将与夏季野外研究的老师和学生与教师和学生互动，以监视波士顿湾查尔斯河口和/或特拉华州河口的水域，以及缺氧的特拉华州内陆海湾。这些将为研究提供巨大的无形但可证明的结果和影响。三名研究生参与了该项目。此外，该项目将为来自广泛学科的本科生提供机会，以参与原位仪器的设计和开发。高中生还将通过教室参与现场测试和夏季实地考察，涉及该项目支持的研究生。通过教室对视频的实现也提到了公共宣传。
