What is Ocean Acidification?
Ocean acidification refers to the process by which the pH level of the ocean decreases, becoming more acidic due to the absorption of carbon dioxide (CO2) from the atmosphere. This phenomenon poses a significant threat to marine life, particularly organisms with calcium carbonate shells or skeletons, such as coral reefs, mollusks, and some plankton species.
Key Concepts
pH Levels
The pH scale measures how acidic or basic a substance is, ranging from 0 to 14, with 7 being neutral. Ocean acidification occurs when the pH of seawater drops, making it more acidic. Pre-industrial ocean pH levels were around 8.2, but they have since dropped to about 8.1 and continue to fall.
Carbon Dioxide (CO2) Absorption
Oceans absorb roughly 30% of the CO2 emitted by human activities. While this helps reduce greenhouse gases in the atmosphere, it also leads to increased acidity in ocean waters.
Calcium Carbonate Saturation
Calcium carbonate is crucial for marine organisms to build shells and skeletons. Increased acidity reduces the availability of carbonate ions, making it harder for these organisms to thrive.
How the Ocean Acidification Calculator Works
The Ocean Acidification Calculator is a handy tool designed to help scientists, environmentalists, and curious minds understand the impact of CO2 on ocean acidity. It uses data inputs such as atmospheric CO2 levels, seawater temperature, and salinity to calculate the pH and carbonate saturation state of seawater.
