Predicting the impact of ongoing anthropogenic CO2 emissions on calcifying marine organisms is complex, owing to the synergy between direct changes (acidification) and indirect changes through climate change (e.g., warming, changes in ocean circulation, and deoxygenation). Laboratory experiments, particularly on

The present study investigated the effectiveness of electromagnetic fields in preventing calcium carbonate (CaCO₃) fouling in cooling water. Four different frequencies and two different voltages were adopted to induce electromagnetic fields directly in water with constant water temperature and constant
