GW : Can Oceans also get warmed by global warming??

There can be some much markable effects of the global warming on the oceans . Lets us first know some important figures before going ahead :

In the period from 1961 to 2003, the temperature of the ocean on the earth from it's surface to a depth of 700m has increased by 0.10 deg. celcius. However, There was some cooling of the ocean water from from 2003 to 2007. Warming in fact reduces the ability of ocean water to absorb the CO2.


Let us see some predicted dangers of warming of ocean :

Anything on warming or heating expands as we all know. So obviously there can be an expansion in the ocean water also. Also additional water from the locked up Ice in the glaciers also will get mixed up with the ocean water to increase its volume. It is predicted that by 2050, the glaciers on the earth will be just 40% of today. As a result the increased volume of water of oceans can result in the engulfing at least the coastal areas of some countries. And the more disastrous results we all know of the global warming.
