It happens quite often that when an aerated drink is poured, we do not consume it all at once. Sip by sip as we devour on a drink and reach half the glass, one finds that the fizz is all gone leaving just sweetened, flavoured water. Don’t we all hate such flat soda? This is because when the drink (liquid) becomes warmer it holds lesser gas as compared to the cold ones. Now, let us consider the ocean water to be that drink and the Indian Ocean, being tropical weather having warmer water paving way to creating of Dead Zones.
