| DIC, TA, calculated pH and carbonate saturation state in the summer bottom water in North Gulf of Mexico from 2006 to 2017 | AS-ALK2 is designed for both laboratory and shipboard use with small sample volume (10 – 25 mL) and high precision (0.1% or better). The titrator is fully automated with standardization and sample analysis. AS-ALK2 provides Gran titration for alkalinity determination of both seawater and brackish waters. Full temperature control is provided on all liquids. Water jackets are used to surround the digital syringes for temperature control. For best data quality, a water bath must be used to supply water with a constant temperature to control the titration temperature. | Semi-automated titrator (AS-ALK2 Apollo Scitech) |

| Monthly cross-shore transects of biogeochemical properties in La Jolla, CA | The open-cell potentiometric acid titration system was developed by the laboratory of A.G. Dickson. Briefly, a known amount of seawater is added to an open cell temperature controlled beaker. Hydrochloric acid (0.1 N) is added using a Methrom Dosimat to a pH of 3.5-4.0. Following equilibration, small increments of hydrochloric acid are then added to the seawater until pH equals ~ 3.0. The titration is monitored by a glass electrode and the total alkalinity of the sample is calculated using a non-linear least-squares method following Dickson et al. (2007). | Open-cell potentiometric acid titrator |
