It would be a never-ending, frustrating process. The east coast cannot be gotten rid of so easily. So with that in mind, this is our adjusted proposal for how to directly test the theory of isostasy. What follows is the science behind the whole idea, and why it would be fun, and why you might want to help. The bit where we explain the theory of isostasy might be a bit dry, but it s important that you understand it, and see why attempting to study it directly would be a huge achievement for science and all mankind.
Icebergs are less dense than the saltwater in which they float.
However, only about one fifth to one tenth of the iceberg is above the water line at any one time. Because the densities are close enough to the same such that the mass of the ice displaces a volume of water approximately four fifths to nine tenths the size of the iceberg. The closer the densities are to each other, the closer the floating object will come to being completely submerged. The depth to mantle is simply the height of the column of interest. The average density of the continental crust is determined largely by approximating the densities of materials through seismic geophysical studies of the region of interest.
