CO2 Sensor System for Long-Term Ocean Monitoring

海洋吸收人为二氧化碳的数量能力存在很大的不确定性。更全面地了解海洋和大气化学之间的关系将扩大科学预测全球变暖的幅度和速度的能力，以便能够制定和实施适当的对策。需要一种分析仪器来连续测量海洋表面上方和下方的二氧化碳浓度。对于所需的大规模研究，该仪器必须在无人值守的情况下运行，允许放置在水面浮标或船只上，并能够将数据传输到中央数据采集站。它将被开发成能够承受海上经常遇到的极端环境条件，并利用一种新的固态传感器技术，该技术具有适合远程监测浅海和深海水域二氧化碳水平的潜在性能和成本特征。拟议的系统将包括数据采集和遥测电子设备，用于在偏远地点进行自动监测。

A large uncertainty exists concerning the quantitative ability of the oceans to take up anthropogenic CO2. A more complete understanding of the relationship between ocean and atmospheric chemistries would broaden the ability of science to predict the magnitude and rate of global warming so that appropriate countermeasures could be developed and implemented. An analytical instrument is needed to make continuous measurements of the CO2 concentration above and below the oceanic surfaces. For the large scale studies needed, the instrument will have to function unattended, allowing placement on surface buoys or ships, and be able to transmit data to a central data collection station. It will be developed to withstand the extreme environmental conditions routinely encountered at sea and utilize a new solid state sensor technology that has the potential performance and cost features suitable for remote monitoring of the CO2 levels in both shallow and deep ocean waters. The proposed system will include the data acquisition and telemetry electronics for automated monitoring at remote locations.
