Since the beginning of the industrial revolution the ocean has become more acidic due to uptake of anthropogenic CO2, a process that is projected to continue under current scenarios. Understanding spatial and temporal variability in carbonate chemistry is essential in order to identify ocean acidification hotspots and begin to predict its effects on marine ecosystems. Traditional ship-based observations cannot offer the spatial or the temporal coverage required to understand global and local variability in the marine CO2 system. Autonomous technology, however, has the potential for large scale high resolution real-time observing (see for example the Argo project www.argo.net) and could accelerate our understanding of how the ocean CO2 cycle is changing. The Ocean Technology and Engineering group at NOC is a world leader in developing ocean sensor technology. Novel sensors for in situ measurements of pH, Total Alkalinity (TA) and Dissolved Inorganic Carbon (DIC) have reached technology readiness for integration and deployment on autonomous platforms enabling, for the first time, direct in situ characterization of the marine CO2 system. The purpose of this project is to optimize and validate these new technologies through new science applications, using the unprecedented resolution of synoptic observations to understand drivers of the marine CO2 system.

自从工业革命开始以来，由于吸收人为CO2，海洋变得更加酸性，该过程预计将在当前情况下继续进行。了解碳酸盐化学的空间和时间变异性对于确定海洋酸化热点至关重要，并开始预测其对海洋生态系统的影响。传统的基于船舶的观察结果不能提供了解海洋二氧化碳系统中全球和局部变异所需的空间或时间覆盖率。但是，自主技术具有大规模高分辨率实时观察的潜力（例如，请参见Argo Project www.argo.net），并且可以加速我们对海洋CO2周期如何变化的理解。 NOC的海洋技术和工程组是开发海洋传感器技术的世界领导者。用于原位测量pH值，总碱度（TA）和溶解的无机碳（DIC）的新型传感器已达到技术准备，以便在自主平台上进行集成和部署，这是首次实现海洋二氧化碳系统的原位表征。该项目的目的是使用新科学应用来优化和验证这些新技术，使用前所未有的概要观测分辨率来了解海洋二氧化碳系统的驱动因素。
