  1. We measured temperature twice daily. We measured salinity, and collected water sampled for total alkalinity (AT) and pH once for the control treatment (i.e. between the two trial blocks), and twice for the reduced pH treatment (i.e. between and after the two trial blocks). We derived pCO2, DIC, and ΩAr from measured values of AT, salinity and pH using CO2SYS. ‡NBS scale.
