Exposing Antarctica's "ghost mountains"

Very interesting stuff. The jaggedness may tell us about the past geoclimate of the southern hemisphere.

I would change the title "Exposing the lost mountains of Antartica" since it had been buried in ice. But I concur. I can't recall who had this theory, but I read somewhere about an explanation where the Earth's outer crust, along with its tectonic plates may be floating on an underground magma layer. For one reason or another, it's as if the outer crust became off balance. To better explain what I mean, it's as if one would suspend a tire in the air and you would add weight on top. If there's any slight disturbance to the tire, the extra weight would off-balance and will reach to the bottom, c... [More]

I think it is interesting that during the maximum period of the last ice age, ocean levels were down almost 120 meters. And that they say if Antarctica melted today ocean levels would go up 60 some meters. So, the Ice Sheet was probably twice as deep in the past.
