Example Bjerrum plot: Change in carbonate system of seawater from ocean acidification.. A Bjerrum plot (named after Niels Bjerrum), sometimes also known as a Sillén diagram (after Lars Gunnar Sillén), or a Hägg diagram (after Gunnar Hägg) [1] is a graph of the concentrations of the different species of a polyprotic acid in a solution, as a function of pH, [2] when the solution is at ...
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]
Another example of a species which may be seriously impacted by ocean acidification is Pteropods, which are shelled pelagic molluscs which play an important role in the food-web of various ecosystems. Since they harbour an aragonitic shell, they could be very sensitive to ocean acidification driven by the increase of anthropogenic CO 2 ...
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. [ 63 ] 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 ...
Ocean acidification makes it harder for organisms to reproduce affecting the ecosystem in the Great Barrier Reef. Species of fish can be affected immensely from ocean acidification which disrupts the overall ecosystem. There is a possible solution that can reverse the affects of ocean acidification called alkalization injection.
There are several other factors that influence the atmosphere-ocean CO 2 exchange, and thus local ocean acidification. These include ocean currents and upwelling zones, proximity to large continental rivers, sea ice coverage, and atmospheric exchange with nitrogen and sulfur from fossil fuel burning and agriculture .

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 .
