The overall objective of this project is to research, develop and produce and demonstrate a prototype pH sensor, utilising a novel self-calibration system, onboard an AUV to a depth of 250 metres.The absorption of CO2 is causing detrimental changes to ocean chemistry. When CO2 reacts with water, carbonic acid is produced causing 'ocean acidification' which is having adverse effects on marine life, including; fisheries, fish farms, shellfish banks and coral reefs. A vast number of sensors will be required to gather the data necessary to understand ocean acidification and its effects, however this is currently not possible due to expense. AUVs are proposed as the solution to the need for making numerous measurements across the World's oceans. The proposed solution is to provide swarms of low cost, small AUVs that collect data for extended periods of time. As such, AUVs are a rapidly growing platform for ocean and water monitoring/management. However, to fulfil the role of a data collection platform, AUV's need sensors that can be deployed on the small/low cost AUV, which requires low cost, small, calibration free sensors.ANB Sensors Ltd (ANB), a UK micro-SME, have identified and filed patents on a disruptive enabling technology, which allows the measurement of pH in demanding (low-salt and low-buffer capacity) aqueous media, such as drinking and seawater. The technology provides accurate measurements (+/- 0.01 pH units), without the need to re-calibrate the sensor; differentiating it from the state-of-the-art. The calibration free operation of ANB's pHenom sensor and its small size mean that the sensor is ideal for use onboard AUVs. This will unlock their wide spread use as data collection platform for ocean and water monitoring/management.

该项目的总体目标是研究、开发、生产和演示一个pH传感器原型，利用一种新型的自校准系统，安装在水下机器人上，可探测到250米深处。当二氧化碳与水反应时，会产生碳酸，导致“海洋酸化”，对海洋生物产生不利影响，包括渔业，养鱼场，贝类银行和珊瑚礁。需要大量的传感器来收集了解海洋酸化及其影响所需的数据，但由于费用问题，目前还无法做到这一点。AUV被提议作为解决需要在世界海洋上进行大量测量的解决方案。建议的解决方案是提供低成本的小型AUV群，以收集长时间的数据。因此，AUV是一个快速发展的海洋和水监测/管理平台。然而，为了实现数据收集平台的作用，AUV需要可以部署在小型/低成本AUV上的传感器，这需要低成本、小型、免校准的传感器。ANB传感器有限公司（ANB）是一家英国微型中小企业，已经确定并申请了一项颠覆性使能技术的专利，该技术允许在要求苛刻的环境中测量pH值。（低盐和低缓冲能力）水性介质，例如饮用水和海水。该技术可提供精确的测量（+/- 0.01 pH单位），无需重新校准传感器;与最先进的技术不同。ANB的pHenom传感器无需校准操作，尺寸小，这意味着该传感器非常适合在AUV上使用。这将释放其作为海洋和水监测/管理数据收集平台的广泛用途。
