Cal Poly Ocean Carbon Lab

 Measurements of carbonate chemistry in seawater are critical to understanding our ocean's (and the Earth's) response to anthropogenic carbon dioxide emissions.

Carbonate chemistry in seawater is typically described by at least two measured variables, chosen from pH, pCO2, total alkalinity, and total dissolved inorganic carbon. The measurement of each of these variables uses unique chemical techniques and instrumentation, each with its own idiosyncrasies, challenges, and advantages! We work to characterize and understand the local seawater chemistry of the Central California Coast, while trying to make these measurements more accurate and reliable for everyone.
