Oceans & CO2

Ocean acidification, sometimes also called “the evil twin of climate change” is the increase of carbon dioxide (CO2) in the oceans, which results in chemical changes that impact marine life.

The first physical evidence of these changes reported by Bednaršek in 2012 has provoked both excitement and worry in the scientific community. Bednaršek’s study recorded changes in the beautiful Limacina helicina antarctica species, a tiny planktonic sea snail including their severe shell dissolution.

Further research demonstrated that while acidification might impair the strength of some species, other marine organisms may benefit.

The effect of CO2 on the sea is that it is becoming more acidic. Various organisms use different forms of calcium carbonate for their shells and thus react differently to these changes. Therefore, while, for example, shells of oysters and scallops grow weaker, other organisms, such as lobsters, and shrimps become more resistant to predators.

So what are the chemical changes of ocean acidification (OA)?

When the seawater absorbs carbon dioxide, the pH and carbonate concentration decreases. These changes will determine the future oceans and the life within.

 

Nowadays, the ocean acidification is monitored to determine its forthcoming impact on oceans and the life within them.
