Because of human-driven increased levels of carbon dioxide in the atmosphere, there is more CO 2 dissolving into the ocean. The ocean’s average pH is now around , which is basic (or alkaline), but as the ocean continues to absorb more CO 2, the pH decreases and the ocean becomes more acidic.
Ocean acidification timeline and effects
Marine scientists are concerned that the process of ocean acidification constitutes a threat to sea life and to the cultures that depend on the ocean for their food and livelihood.
What causes ocean acidification
What causes ocean acidification? Ocean acidification is mainly caused by carbon dioxide gas in the atmosphere dissolving into the ocean. This leads to a lowering of the water's pH, making the ocean more acidic. Carbon dioxide is being produced faster than nature can remove it, so increasing amounts are being absorbed by the ocean. Ocean acidification is the long-term, global decrease in seawater pH caused primarily by the ocean’s uptake of carbon dioxide (CO₂) from the atmosphere. As CO₂ dissolves into seawater, it alters carbonate chemistry that many marine organisms rely on to build shells and skeletons.
Causes and consequences of ocean acidification
Because of human-driven increased levels of carbon dioxide in the atmosphere, there is more CO 2 dissolving into the ocean. The ocean’s average pH is now around , which is basic (or alkaline), but as the ocean continues to absorb more CO 2, the pH decreases and the ocean becomes more acidic.
The science behind ocean acidification
Explanation of the sources of pollution that cause ocean and coastal acidification, as well as the basic science behind these phenomena.
Step-by-step explanation of ocean acidification process
Ocean acidification is caused by the increase of carbon dioxide in the atmosphere that are dissolved into the oceans. This aqueous carbon dioxide reacts with the water to form carbonic acid. This diagram outlines the process in a step by step guide for easier understanding.
How carbon dioxide affects ocean ph levels
Because of human-driven increased levels of carbon dioxide in the atmosphere, there is more CO 2 dissolving into the ocean. The ocean’s average pH is now around , which is basic (or alkaline), but as the ocean continues to absorb more CO 2, the pH decreases and the ocean becomes more acidic.
