Purpose of Review

We summarize recent progress on autonomous observations of ocean carbonate chemistry and the development of a network of sensors capable of observing carbonate processes at multiple temporal and spatial scales.

Recent Findings

The development of versatile pH sensors suitable for both deployment on autonomous vehicles and in compact, fixed ecosystem observatories has been a major development in the field. The initial large-scale deployment of profiling floats equipped with these new pH sensors in the Southern Ocean has demonstrated the feasibility of a global autonomous open-ocean carbonate observing system.

Summary

Our developing network of autonomous carbonate observations is currently targeted at surface ocean CO2 fluxes and compact ecosystem observatories. New integration of developed sensors on gliders and surface vehicles will increase our coastal and regional observational capability. Most autonomous platforms observe a single carbonate parameter, which leaves us reliant on the use of empirical relationships to constrain the rest of the carbonate system. Sensors now in development promise the ability to observe multiple carbonate system parameters from a range of vehicles in the near future.

观察海洋碳酸盐化学的变化:我们自主的未来。

审查目的

我们总结了海洋碳酸盐化学自主观测的最新进展,以及能够在多个时间和空间尺度上观测碳酸盐过程的传感器网络的发展。

最近的发现

适用于自动驾驶汽车和紧凑型固定生态系统观测站的多功能 pH 传感器的开发一直是该领域的一项重大发展。配备这些新型 pH 传感器的剖面浮标在南大洋的初步大规模部署证明了全球自主公海碳酸盐观测系统的可行性。

概括

我们正在开发的自主碳酸盐观测网络目前针对海洋表层 CO 2通量和紧凑型生态系统观测站。在滑翔机和地面车辆上开发的传感器的新集成将提高我们的沿海和区域观测能力。大多数自主平台观察到单个碳酸盐参数,这使我们依赖于使用经验关系来约束碳酸盐系统的其余部分。目前正在开发的传感器有望在不久的将来从一系列车辆中观察多个碳酸盐系统参数。
