Ocean Acidification
A precise tool.
What is the Ocean Acidification & How does it work?
Ocean acidification occurs when excess carbon dioxide (CO₂) from the atmosphere dissolves into seawater, forming carbonic acid and lowering pH. This shift alters the carbonate chemistry that marine organisms rely on for shell and skeleton formation. The fundamental reaction can be expressed as: Because the ocean buffers CO₂ through the carbonate system, changes in atmospheric CO₂, temperature, alkalinity, and dissolved inorganic carbon (DIC) collectively determine the magnitude of pH decline, impacting ecosystems from coral reefs to plankton.
pH = -\log_{10}[H^{+}]
[H^{+}] = hydrogen ion concentration (mol/L)

Frequently Asked Questions
What is ocean acidification?
Ocean acidification occurs when excess CO₂ from the atmosphere dissolves in seawater, lowering its pH and affecting marine organisms’ ability to form shells and skeletons.
How does temperature affect ocean acidification?
Higher temperatures can increase the rate of ocean acidification by reducing the amount of dissolved oxygen and altering the carbonate chemistry of the water.
What is the fundamental reaction in ocean acidification?
The fundamental reaction is pH = -log[H⁺], where [H⁺] represents the hydrogen ion concentration in moles per liter.
How does alkalinity buffer CO₂ in the ocean?
Alkalinity helps to neutralize excess CO₂ by providing bicarbonate and carbonate ions that react with hydrogen ions, thus reducing their concentration and mitigating acidification.
What are the impacts of ocean acidification on marine life?
Ocean acidification can lead to weakened shells and skeletons in calcifying organisms like corals, mollusks, and plankton, affecting entire ecosystems and biodiversity.
How does this calculator work?
This calculator uses inputs such as atmospheric CO₂ levels, temperature, alkalinity, and dissolved inorganic carbon to estimate the potential impact of ocean acidification on marine environments.
What are some ways to mitigate ocean acidification?
Reducing global CO₂ emissions, restoring coastal ecosystems like mangroves and seagrasses, and implementing sustainable fishing practices can help mitigate ocean acidification.
