Answer
An increase in pressure on the surface of water increases the solubility of a gas in water.
For example: the solubility of carbon dioxide in water under normal atmospheric pressure is rather low, but when the water surface is subjected to higher pressure, a lot more carbon dioxide gas dissolves in it, as is seen in the case of soda water. On opening the soda water bottle, the dissolved gas rapidly bubbles out since pressure on the surface of the water suddenly decreases.
