Calcium carbonate dissolution below the lysocline impacts ocean carbon chemistry
Is it true that calcium carbonate dissolution below the lysocline impacts ocean carbon chemistry?
Yes. Calcium carbonate dissolution in the ocean is a foundational component of marine carbon chemistry and the global carbon cycle, helping buffer atmospheric CO2.
Verdict: SUPPORTED · 3 sources for, 0 against · Last checked
The retrieved papers consistently support the premise that calcium carbonate dissolution impacts ocean carbon chemistry, acting as a critical regulator of marine alkalinity and carbon cycles. None of the provided literature refutes this well-established oceanographic mechanism.
