Ahoy, ocean aficionados! Ever pondered how tangy our vast oceans are turning? You’ve anchored at the right place. Welcome aboard the S.S. Ocean Acidification Calculator. No more shilly-shallying, let’s plunge right in!
The Formula
pH = -log10([H+])
In this formula, pH is the measure of acidity, and [H+] represents the concentration of hydrogen ions in the water.

FAQs
- What is Ocean Acidification? Ocean acidification refers to the process where seawater becomes more acidic due to an uptake in CO2 from the atmosphere.
- What is the current average pH of the ocean? The current average pH of the ocean is approximately 8.1.
- Why is ocean acidification a concern? Ocean acidification can harm marine life, particularly organisms with calcium carbonate shells or skeletons.
- What causes ocean acidification? The main cause of ocean acidification is the increase in CO2 in the atmosphere, much of which is absorbed by the oceans.
- How does ocean acidification affect marine life? It can make it harder for organisms to form and maintain their shells, and it can affect the behavior and survival of some fish species.
- What is the pH scale? The pH scale measures how acidic or basic a substance is, ranging from 0 (most acidic) to 14 (most basic).
- How is ocean pH measured? Ocean pH can be measured using various methods, such as spectrophotometry or electrochemical measurements.
- What can be done to reduce ocean acidification? The most effective way to reduce ocean acidification is to decrease CO2 emissions.
- How does temperature affect pH? Generally, as temperature increases, the pH of water decreases and vice versa.
- Are there alternatives to pH for measuring ocean acidification? Yes, one such alternative is measuring alkalinity, although it’s less accurate.
