if plato’s atlantis was as he discribed it, then its subsidence to the current depth of the atlantic ocean floor will remove 3 million cubic miles of rock from the volume of the ocean basin. Closing in and filling that volume will cause the global see level to drop 150 feet, largely offsetting the rise in sea level caused by the filling of the the ocean basins with glacial melt water at the end of the last ice age.
