Topic: Large Crack in Antarctic Ice

yes, the thermal expansion of water does look to be a a big player in sea level rise (and fall during colder periods)
when you think about it, the oceans are really not all that deep compared to the size of the planet
i.e think along the lines more like a relatively thin layer of water spread across the surface...expand that thin layer, and it will spread across the (relatively flat compared to size ) surface even more (ie as the volume increases)

  That is true.  I never really thought about the depth in relation to the size of the Earth.  Interesting.....

What about the Earth contracting as the core cools?  The more solid surfaces would shrink towards the core while the liquid would remain relatively the same but cover more of the land mass.

Too many SciFi movies?
