The PIs propose to use the NOPP Topic 4B funding to promote commercialization of their Submersible Autonomous Moored Instrument, SAMI-CO2, a sensor developed for autonomous measurements of the partial pressure of CO2 (pCO2). Field deployments by the PI and others have demonstrated the excellent long-term stability predicted by SAMIs' well-understood theoretical response. The PIs propose to redesign the sensor to improve reliability, make it more user friendly and to implement modern electronic and manufacturing technologies. The new design will allow individual investigators to make pCO2 measurements reliably over long time periods in widespread ocean locations on many different ocean platforms. Broader ImpactsThe proposed work will not only increase the availability of autonomous pCO2 sensors but will also provide the means for quantifying total inorganic carbon through pH-alkalinity or pCO2-alkalinity calculations. The research directly addresses an important need for chemical sensors for implementing ocean observatory systems such as the IOOS with systems to determine impacts of chemical species in the oceans.

PI建议使用NOPP主题4 B资金来促进其潜水自主系泊仪器SAMI-CO2的商业化，SAMI-CO2是一种用于自主测量CO2分压（pCO 2）的传感器。PI和其他人的实地部署已经证明了SAMI良好理解的理论响应所预测的出色的长期稳定性。PI建议重新设计传感器，以提高可靠性，使其更加用户友好，并实施现代电子和制造技术。新的设计将允许个人调查人员在许多不同的海洋平台上的广泛海洋位置长时间可靠地进行pCO 2测量。更广泛的影响拟议的工作不仅将增加自主pCO 2传感器的可用性，而且还将提供通过pH-碱度或pCO 2-碱度计算量化总无机碳的方法。这项研究直接解决了实施海洋观测系统（如IOOS）所需的化学传感器的重要需求，该系统具有确定海洋中化学物种影响的系统。
