The PIs request funding to develop, groundtruth, and deploy an in-situ sensor for continuous seawater DIC measurements on mobile observing platforms. The system will be capable of continuous, submersible measurements in-situ up to a depth of 3000m in the ocean. It will be designed and built primarily for deployment on AUVs and CTD-Rosette packages where fast response sensors are preferred. Because of the micro-flow characteristic, the sensor will have low power and reagent consumption tailored to the size and power requirements for underwater vehicles. The proposed sensor will be capable of measuring DIC accurately with high-resolution on mobile platforms. With nominal calibrations and testing, the new sensor will also be able to make continuous measurements of seawater pCO2 using a similar method.Broader Impacts: The proposed work will promote teaching through the supervision of one female doctoral student and the training of at least one summer student through an educational program targeted for underrepresented groups in science. The development of a fast-response in-situ DIC sensor is certainly of interest for a broader community, and there is potentially a large enough market for the commercialization of this sensor. This instrumentation has the potential to provide high-resolution total CO2 measurements for several ocean research fields, ranging from ocean acidification to climate change. The sensor is proposed to be deployed in Buzzard Bay, MA in cooperation with the Buzzards Bay Coalition. The technology will be presented through the "Science Made Public" summer series.

PI要求提供资金，用于开发、地面实况和部署现场传感器，用于在移动的观测平台上进行连续的海水DIC测量。该系统将能够在海洋3000米深处进行连续的水下原位测量。它的设计和建造主要是为了部署在AUV和CTD玫瑰包中，其中快速响应传感器是首选。由于微流特性，传感器将具有低功率和试剂消耗，以适应水下航行器的尺寸和功率要求。该传感器将能够在移动的平台上以高分辨率精确测量DIC。通过标称校准和测试，新传感器还将能够使用类似的方法连续测量海水pCO2。 拟议的工作将通过一名女博士生的监督促进教学，并通过一项针对科学领域代表性不足的群体的教育方案培训至少一名暑期学生。快速响应的原位DIC传感器的开发肯定会引起更广泛的社区的兴趣，并且这种传感器的商业化可能有足够大的市场。该仪器有可能为从海洋酸化到气候变化等多个海洋研究领域提供高分辨率的二氧化碳总量测量。该传感器拟与布扎德湾联盟合作部署在马萨诸塞州的布扎德湾。该技术将通过“科学公开”夏季系列展示。
