I am sure all of you have heard the old ice in a glass of water thing. Right? How ice doesnt displace less water than water so if the glaciers all melt the ocean level will not rise as much as other people claim. I have no idea if that is right or not. But, I wonder if anyone has done any research on how much the amount of water frozen in the glaciers expaned when it froze. I am curious how much more space the glaciers take up because of the expansion of the water when it froze. Its probably relatively small but when talking about that much water I imagine it is a lot of space.
