Ocean Acidification - Definition, glossary, details

The oceans absorb certain amount of carbon dioxide from the atmosphere that is released during combustion of fossil fuels. But, over a period of time this has led to acidification of ocean, that is, reduction in pH value of the water. This process is termed as ocean acidification. It is estimated that since the beginning of industrial revolution, the pH of the ocean has reduced by 0.1pH units. The carbon dioxide absorbed by oceans gets dissolved in the water to become carbonic acid which released hydrogen ions into the solution. Acidity is the measure of the hydrogen ions in the water, where an increase in hydrogen leads to increase in acidity and subsequent decrease in pH value.
