The dynamic ocean acidification manipulation experimental system: Separating carbonate variables and simulating natural variability in laboratory flow‐through experiments
Abstract Carbonate chemistry variables such as PCO 2 , pH, and mineral saturation state ( Ω ) are commonly thought of as covarying in open‐ocean settings but have decoupled over geologic time‐scales and among modern dynamic coastal margins and estuaries. Predicting responses of vulnerable coastal or...
