Microscopic pictures of individual foraminifers ... The green colour is caused by seawater with an indicator showing that the acidity has changed. The actual size of the foraminifer is about ...

Ocean acidification is the lowering of seawater pH over time, as the ocean absorbs carbon dioxide (CO 2) from the atmosphere. The pH scale is used to measure how acidic or basic a water-based solution ...

Ocean water is naturally slightly alkaline, but as it absorbs excess carbon dioxide from the atmosphere, its pH drops, ...

Carbon is key for understanding ocean acidity, especially in the 21st century. As global emissions increase, more and more carbon dioxide leaches into seawater from the atmosphere, making it more ...
