Automated in-situ instrumentation has been developed for sensitive, precise and accurate measurements of a variety of analytes in natural waters. In this work we describe the use of ‘SEAS’ (Spectrophotometric Elemental Analysis System) instrumentation for measurements of solution pH. SEAS-pH incorporates a CCD-based spectrophotometer, an incandescent light source, and dual pumps for mixing natural water samples with a sulfonephthalein indicator. The SEAS-pH optical cell consists of either a liquid core waveguide (LCW, Teflon AF 2400) or custom-made PEEK tubing. Long optical pathlengths allow use of indicators at low concentrations, thereby precluding indicator-induced pH perturbations. Laboratory experiments show that pH measurements obtained using LCW and PEEK optical cells are indistinguishable from measurements obtained using conventional spectrophotometric cells and high-performance spectrophotometers. Deployments in the Equatorial Pacific and the Gulf of Mexico demonstrate that the SEAS-pH instrument is capable of obtaining vertical pH profiles with high spatial resolution. SEAS-pH deployments at a fixed river-site (Hillsborough River, Fla.) demonstrate the capability of SEAS for observations of diel pH cycles with high temporal resolution. The in-situ precision of SEAS-pH is better than 0.002 pH units, and the system's measurement frequency is approximately 0.5 Hz. This work indicates that in-situ instrumentation can be used to provide unique capabilities for observations of carbon-system transformations in the natural environment.
