项目摘要

The DuraFET pH sensor is a key component of global observation networks through coordinated efforts such as Biogeochemical Argo and the Global Ocean Acidification Observation Network. These pH sensors have been deployed on hundreds of autonomous profiling floats, underwater gliders, and moorings to study ocean carbon cycling in environments ranging from the intertidal zone, coral reefs, to the open ocean. Additionally, they are commonly utilized in laboratory mesocosms to study impacts of ocean acidification. The key enabling technology for the DuraFET is an Ion Sensitive Field Effect Transistor (ISFET) semiconductor chip, manufactured by Honeywell Co. The Honeywell ISFET has several unique features that give it superior performance relative to its competitors. This in essence results in a sole-source for DuraFET pH sensors, and represents a key vulnerability for ocean carbon monitoring. To address this, this proposal aims to accelerate the development of alternative pH sensors that can be scaled to fit the current needs of global ocean observational networks.Specifically, this project will test and develop two promising pH sensor candidates that are capable of long-term deployments (years) to 2 km depth on autonomous platforms such as profiling floats and gliders, as well as for moored instrumentation and laboratory mesocosm applications. First, the performance of a commercially available optical pH optode sensor (distributed by PyroScience) will be assessed. This is a relatively new sensor for oceanography, thus its performance has not been thoroughly characterized to the satisfaction of chemical oceanographers. Second, a pH sensor that utilizes an ISFET from a different supplier will be developed. Both pH sensors that will be explored are solid state, small, and low-power, making them good candidates for autonomous platforms. The sensors will be thoroughly characterized in the laboratory for pH response, long term drift, salinity, temperature, and pressure effects, response time, and hysteresis. Both sensors will then be deployed on coastal moorings, underwater gliders, and profiling floats to assess in situ performance across a range of conditions over months to years. Results from this development will be rapidly and efficiently shared with the oceanographic community through recurring webinars, publications, and collaboration with industry.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
DuraFET pH传感器是通过生物地球化学Argo和全球海洋酸化观测网络等协调努力建立的全球观测网络的关键组成部分。这些pH传感器已被部署在数百个自主剖面浮标、水下滑翔机和系泊设备上,用于研究从潮间带、珊瑚礁到公海等环境中的海洋碳循环。此外,它们通常用于实验室中围生态系统,以研究海洋酸化的影响。DuraFET的关键使能技术是霍尼韦尔公司制造的离子敏感场效应晶体管(ISFET)半导体芯片。霍尼韦尔ISFET具有几个独特的功能,使其相对于竞争对手具有上级性能。这实质上导致了DuraFET pH传感器的唯一来源,并代表了海洋碳监测的一个关键弱点。为解决这一问题,该项目旨在加速开发可按比例调整以满足全球海洋观测网络当前需求的替代pH传感器,具体而言,该项目将测试和开发两种有前途的pH传感器候选产品,这些传感器能够在剖面浮标和滑翔机等自主平台上长期部署(数年)至2公里深度,以及用于系泊仪器和实验室围隔应用。首先,将评估市售光学pH光电二极管传感器(由PyroScience分销)的性能。这是一个相对较新的海洋学传感器,因此其性能尚未得到充分表征,以满足化学海洋学家的要求。其次,将开发利用来自不同供应商的ISFET的pH传感器。将被探索的两种pH传感器都是固态、小型和低功耗的,使它们成为自主平台的良好候选者。传感器将在实验室中进行pH响应、长期漂移、盐度、温度和压力效应、响应时间和滞后的全面表征。然后,这两种传感器将被部署在沿海系泊设备、水下滑翔机和剖面浮标上,以评估数月至数年内各种条件下的现场性能。这一发展的成果将通过定期的网络研讨会、出版物和与行业的合作与海洋学界快速有效地分享。该奖项反映了NSF的法定使命,并通过使用基金会的知识价值和更广泛的影响审查标准进行评估,被认为值得支持。
