Initially, many scientists focused on the benefits of the ocean removing this greenhouse gas from the atmosphere. However, decades of ocean observations now show that there is also a downside — the CO 2 absorbed by the ocean is changing the chemistry of the seawater, a process called ocean acidification. This change in the ocean’s chemistry ...
Ocean acidification means that the average seawater pH value is dropping over time. [1]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. [2]
Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming. These impact marine ecosystems and food webs and may result in consequences as yet unrecognised for the biodiversity and continuation of marine life forms. [3]
Changes in the balance between terrestrial weathering and sedimentation of carbonate minerals (for example, as a function of ocean acidification) are the primary long-term drivers of alkalinity in the ocean. [19] Over human timescales, mean ocean alkalinity is relatively stable. [20] Seasonal and annual variability of mean ocean alkalinity is ...
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. [ 21 ] Carbon dioxide emissions from human activities are the primary cause of ocean acidification, with atmospheric carbon dioxide (CO 2 ) levels exceeding 422 ppm (as of ...

Estuarine acidification happens when the pH balance of water in coastal marine ecosystems, specifically those of estuaries, decreases. Water, generally considered neutral on the pH scale , normally perfectly balanced between alkalinity and acidity .
It is believed that this high stress environment will cause ocean acidification factors to have a stronger effect on these organisms. It could also cause these effects to appear in the Arctic before it appears in other parts of the ocean. There is a significant variation in the sensitivity of marine organisms to increased ocean acidification.
