Flow injection TA analyzer

To collect these measurements systems are required to perform climate-quality, highly accurate analysis of the concentration of carbon dioxide in seawater. The system must be able to be deployed on oceanographic and laboratory-based platforms, allowing for remote, autonomous, high-resolution measurements of seawater total alkalinity to be made of flowing seawater every 3–10 minutes.

Additionally, the system must be capable of interfacing with the underway CO2 analytical systems used by the PMEL Carbon Group to work in conjunction with the system, allowing for measurements to be recorded alongside surface seawater CO2 measurements. The measurements these systems will be ready to make are of critical importance in our effort to constrain the rates of ocean acidification (i.e., increasing CO2 and acidity) in coastal ecosystems of the Pacific Coast of North America.
