Ocean acidification | Definition, Causes, Effects, Chemistry,
WebApr 14, 2024 · Ocean acidification, the worldwide reduction in the pH of seawater as a consequence of the absorption of large amounts of carbon dioxide by the oceans. It is largely the result of loading Earth’s atmosphere with large quantities of carbon dioxide, produced by vehicles and industrial and agricultural processes.
What is Ocean Acidification? - NOAA's National Ocean Service
WebOcean acidification refers to a reduction in the pH of the ocean over an extended period time, caused primarily by uptake of carbon dioxide (CO2) from the atmosphere. An official website of the United States government.

WebOcean acidification is sometimes called “climate change’s equally evil twin,” and for good reason: it's a significant and harmful consequence of excess carbon dioxide in the atmosphere that we don't see or feel because its effects are happening underwater.
Ocean acidification - Wikipedia
WebOcean acidification means that the average ocean pH value is dropping over time. Ocean acidification is the ongoing decrease in the pH of the Earth's ocean. Between 1950 and 2020, the average pH of the ocean surface fell from approximately 8.15 to 8.05.

Ocean Acidification | National Oceanic and Atmospheric Administration
WebOcean Acidification. The ocean's role in the global carbon cycle. The ocean has become more acidic over the past century because of an increase in the amount of carbon dioxide it is absorbing from the atmosphere, leading to a lower pH and greater acidity. This is causing a fundamental change in the chemistry of the ocean from pole to pole.
