Carbon dynamics of Florida Bay: spatiotemporal patterns and biological control

Carbon dynamics of Florida Bay is manifested by wide ranges of pH (7.65–8.61), dissolved inorganic carbon (DIC, 929–3223 ?M) and partial pressure of CO2 (pCO2, 50–1313 ?atm) observed over seven years. Despite the seasonal variation, a decline of ?0.0066 pH per year was observed as a result of ocean acidification and the spatiotemporal patterns were […]
